A. 1. Labels of digestive organs
A. 2. The function of digestive organs

The mouth is the beginning of the digestive process. As food enters the mouth, the teeth begin breaking down the food and mixing with the saliva. The mouth functions in the beginning of the digestive process. The teeth begins to breakdown the food particles and mixes with the saliva. From the mixture of food and saliva travels to the stomach. The stomach begins to secrete gastric enzymes that combine with the food. As the food continues through the duodenum

The stomach receives the food particles and begin to mix with the gastric juices to further breakdown the food.

The liver

The gallbladder

Duodenum

Jejenum

Ascending Colon

A. 3. Summarization of mechanical and chemical digestion
Mechanical Digestion - Food is crushed and liquefied by the teeth, tongue, and peristaltic contractions (waves of involuntary muscle contraction) of the stomach and small intestine. This creates a greater surface area for the digestive enzymes to work upon.
Chemical Digestion - Many glandular structures, dispersed throughout the body, are involved in breaking food into simple molecules that can be absorbed. In the mouth, the salivary glands produce saliva, which both lubricates food and begins the process of starch digestion. Saliva contains salivary amylase (ptyalin), an enzyme that digests starch to maltose (a disaccharide). As food leaves the mouth, the esophagus conducts it to the stomach via the cardiac sphincter by means of peristaltic waves of smooth muscle contraction.

A. 4. Examples of enzymes that digest carbohydrates, proteins, and lipids

Amylase break down carbohydrates. Sucrase break down carbohydrates. Mycozyme break down carbohydrates. Protease break down proteins. Pepsin break down proteins. Trypsin proteins. Duodenal enterokinase…...

...She turned around to run out of the dark room he’d pushed her into, and just like that, there was a knife in her occipital. She wasn’t dead yet, just suffering. Her integumentary could still feel every cut being made on her anatomy. She was finally relieved when her nervous system shut down and her life slipped away. The Villain could see the relief in her orbitals . . . so he carved them out and put them in his pocket. Alexander Morgan woke up sweating profusely from his axillaries, along with the entire posterior of his body. His deltoids were sore and his cranial ached. When he tried to sit up, a chord attached to his pectoral held him back and he realized that there was a searing pain in that same spot. He put his dorsum to the side of his mental and realized there were tiny cuts. He looked down and saw a sagittal slit down his thoracic cavity. “Dr. Morgan, you’ve been in a coma for three days now, you were attacked.” explained the doctor. “Attacked? By who?” “The police believe it was the work of The Villain.” Suddenly, it all became clear to him. The Villain was real, and wasn’t just someone Alexander Morgan dreamed about. It seemed like déjà vu. The real Alexander Morgan was not a detective, in fact he had a doctorate degree in physiology. He decided that was why his dream was so technical. Everything was coming together . . . his profession, the actual existence of The Villain. It was all so clear. “Dr. Morgan, we’re afraid that the positive feedback......

Anatomy and Physiology of Respiratory System

...Anatomy and Physiology of Respiratory System Overview Cells in the body require oxygen to survive. Vital functions of the body are carried out as the body is continuously supplied with oxygen. Without the respiratory system exchange of gases in the alveoli will not be made possible and systemic distribution of oxygen will not be made possible. Thetransportation of oxygen in the different parts of the body is accomplished by the blood of the cardiovascular system. However, it is the respiratory system that carries in oxygen to the body and transports oxygen from the tissue cells to the blood. Thus, cardiovascular system and respiratory system works hand in hand with each other. A problem in the cardiovascular system would affect the other and vice versa. Functional Anatomy of the Respiratory System Nose The nose is the only external part of the respiratory system and is the part where the air passes through. During inhalation and exhalation, air enters the nose by passing through the external nares or nostrils. Nasal cavity is found inside the nose and is divided by a nasal septum. The receptors for the sense of smell, olfactory receptors are found in the mucosa of the slit-like superior part of the nasal cavity which is located beneath the ethmoid bone. Respiratory mucosa lines the rest of the nasal cavity and rests on a rich network of thin-walled veins that warms the air passing by. Important information about nose is the presence of the sticky mucus that is......

...Anatomy and Physiology 2, SCI 136 Research Project Number 40904000. There are many different types of Arthritis. Some of these types are caused by infections, some by injury, some by aging, and some by entirely unknown causes. Infectious arthritis may follow influenza, typhoid fever, tuberculosis, syphilis or gonorrhea. Arthritis of an unknown cause is common and Rheumatoid arthritis is the worst form. Chronic arthritis is common. It has three main forms: osteoarthritis, rheumatoid arthritis, and gout. Osteoarthritis is an inflammatory condition of one or more joints the main symptoms of arthritis are joint pain and stiffness, which typically worsen with age. This is the most common form of arthritis. This disease is known as a degenerative joint disease. It affects about 80% of all Americans. The pain is caused by the degeneration of the joint. The damage to the cartilage occurs as the disease progresses and degenerates and may form some bony spurs at the end of the bones. The bones may grind against each other. Cartilage normally serves as a shock-absorbing cushion between the bones. When it breaks down it results in bones rubbing directly against one another during movement. This friction between the bones causes the bone to thicken, and spurs develop .As time goes on; these abrasions can cause permanent joint damage. Osteoarthritis is most common in the knees, hips, hands and spine. Rheumatoid arthritis is the worst form arthritis. It is a chronic......

...Throughout this assignment the anatomy and physiology of the central nervous will be examined in relation to the affects a stroke may cause. The causes and symptoms will also be identified along with the various affects a stroke may have on an individual such as physical, emotional, and social impact. Finally, the care and treatments provided will be highlighted and will be referenced throughout according to relevant literature and guidelines such as Infection control, Health and Safety, and various government policies. According to the National Stroke Strategy 2007, a stroke is a condition in which the brain cells suddenly die due to a lack of oxygen. A stroke is often caused by an obstruction in the blood flow, or the rupture of an artery that feeds the brain (reference). The two main types of stroke which will be referred to throughout the text are hemorrhagic and Ischemic. National Stroke Strategy (2007) states that ‘an Ischemic stroke accounts for around 87% of all strokes and occurs when a blood clot (thrombus) forms that blocks the blood flow to a certain part of the brain’. When a blood clot forms somewhere in the body and breaks off to become free-floating, it is called an embolus (reference). This wandering clot may then be carried through the bloodstream and to the brain where it can then cause an ischemic stroke. A hemorrhagic stroke occurs when a blood vessel on the brain's surface ruptures and then fills the space between the brain and skull with blood or when...

Reflection on Intro to Physiology/Anatomy

...We started with the introduction to anatomy by defining it as the scientific discipline that investigates the structure of the body. I have discovered that there are two basic approaches to the study of anatomy are systematic (by system) and regional (by area), the latter which is more commonly used in most medical schools. And of course studying the structure is not enough, this is where physiology comes in which is the scientific discipline that deals with the processes or functions of living things. I have known homeostasis as the maintenance of the relatively constant environment in the body but it is only now that I have learned about positive and negative feedback mechanisms which maintain homeostasis and that positive homeostasis can be detrimental at times. I’ve also learned more on the anatomical terms that will be used throughout our course and maybe even in med school. In the study of cells, I was able to recall the things we have discussed in our biological science course in the previous year. I remember the three types of solution namely hypotonic, isotonic, and hypertonic. I also come to know more about the different movements across the cell membrane. However I was new to the transcription and translation that happens in the gene expression of a cell. I was able to associate codons of the mRNA strand with the anticodon of the tRNA. Similar to cytology, I was also able to look back on our discussions about tissues last year. I have refreshed myself on......

...epithelium consists of several layers of cells; cells in the apical layer are column-shaped (Table 4.1H). It is found in a portion of the male urethra and large excretory ducts of some glands. It functions in protection and secretion. Transitional epithelium consists of several layers of cells whose appearance varies with the degree of stretching (Table 4.1I). It lines the urinary bladder. A gland is a single cell or a group of epithelial cells adapted for secretion. Endocrine glands secrete hormones into interstitial fluid and then the blood (Table 4.2A). Exocrine glands (mucous, sweat, oil, and digestive glands) secrete into ducts or directly onto a free surface (Table 4.2B). ❑ ❑ © 2013 John Wiley & Sons, Inc. All rights reserved.

The Anatomy and Physiology of the Respiratory System

...the baby is usually stimulated so that it begins to cry. As soon as the baby cries for the very first time, and gasps for its first breath of air, this will actually cause the bronchiole tree to inflate. And once it inflates, subsequent breaths will continue the inflation until the baby is able to breathe on his or her own. When we age, elastic tissue will deteriorate causing lower lung compliance. Chest movements are restricted by arthritis. And some changes of emphysema naturally occurs with age. And of course smoking can increase the risk of emphysema, but emphysema is defined as a chronic, progressive condition, characterized by shortness of breath, and inability to tolerate physical exertion.

...Anatomy and Physiology Task 1 1. Discuss your dissection of the sheep heart and the cardiovascular system of the fetal pig by doing the following: a. Describe the similarities and differences between the fetal pig heart and the sheep heart. Differences: 1. Size 2. The left ventricular wall is thicker in the sheep than the fetal pig. Similarities: They both have 2 atria and 2 ventricles. b. Describe the four valves of the heart, including their name, location, and function. The four valves of the heart are the tricuspid valve, the pulmonic valve, the mitral valve, and the aortic valve. The tricuspid valve: It is located between the right atria and the right ventricle. It is comprised of three “flap-like cusps” which when in its closed position, prevents the deoxygenated blood entering the heart from the body, from backing up in the right atrium from the right ventricle (regurgitation). http://www.healthline.com/human-body-maps/tricuspid-valve The Pulmonic Valve: This valve is found between the right ventricle and the lungs. As the deoxygenated blood continues on its journey through the heart from the right ventricle, it makes its exit by way of the pulmonic valve. This structure is a one-way valve with prevents the flow of blood back into the right ventricle once it leaves the heart. http://www.healthline.com/human-body-maps/pulmonary-valve The mitral valve: This valve is located between the left atrium and the left ventricle. As the now oxygenated blood......

In  this assignment I will be explaining the physiology  of two named body systems in relation to energy metabolism in the body. Firstly,  I  will  start off by giving a definition of energy metabolism in the body. Metabolism in the body   is  a  collection  of  chemical  reactions  that  takes  place   in  the  body’s  cells.  Metabolism converts  the  nutrients  in  the food  that we eat in  to essential energy which is needed to power all  that  we  do,  from  something  as  little  as  thinking  to  growing  physically  or  carrying  out  a physical  activity.  In  our  body’s,  there  are  specific  proteins  which   controls  the  chemical reactions of metabolism. http://kidshealth.org/teen/your_body/body_basics/metabolism.html Secondly,  the  two  body  systems that  I  will write  about  in  relation  to  energy  metabolism  are: the cardiovascular system and the digestive system. The cardiovascular system. The  heart  is  the  vital  muscle  that  pumps  blood  around  the  body  through arteries,  capilleries and  veins.  One of the functions of the heart  is to carry around blood which contains dissolved oxygen  to  the  body cells and then banishes  any wastage of respiration. The blood in  our body also......

Anatomy and Physiology

...Summary Week 1 Discussion This discussion we looked at two examples of the heart and its functions. Atrial septal defect (ASD) is fairly common. This was a terrific example to relate structure and function. When the structure of anatomy is disrupted we can see as in this example how normal function is altered. This congenital defect allows blood to flow between atria instead of the normal flow through the ventricles and to the body and the disrupted and limited blood flow can lead to heart failure, stroke and pulmonary hypertension. The larger the hole the more quickly surgery is needed to correct it. Smaller holes may provide enough blood flow to avoid these complications and may heal over on its own. Ventricular septal defect (VSD) is less common. A hole between the ventricles allows mixing of oxygenated blood from the lungs with de-oxygenated blood returning from the body. Heart failure and infections occur rapidly due to the lack of oxygenated blood reaching the body and the baby often presents with a bluish discoloration to the skin as a result of lack of oxygen. Artificial hearts being developed run on batteries to pump the blood and include porting valves to ensure blood flow goes in the correct direction. Essential characteristics of an artificial heart that would make them ideal would be to mimic the real heart in structure and function and resist rejection in the recipient.
