Study Notes
Digestive System
- Lipase is the enzyme responsible for breaking down lipids in the digestive system.
- Chyme is the term used to describe the mixture of partially digested food and digestive juices in the stomach.
- The ileocecal sphincter separates the small intestine from the large intestine.
- The small intestine is responsible for the majority of nutrient absorption in the human digestive system.
- The pyloric sphincter controls the flow of food from the stomach to the small intestine, allowing only partially digested food to enter the small intestine.
Digestive Enzymes
- Amylase breaks down carbohydrates into simple sugars in the digestive system.
Cardiovascular System
- The three layers of the heart wall are:
- Epicardium: the outermost layer, which is a thin layer of connective tissue that protects the heart and anchors it to surrounding tissues.
- Myocardium: the middle layer, which is the thick layer of cardiac muscle responsible for contracting to pump blood.
- Endocardium: the innermost layer, which is a thin layer of epithelial tissue that lines the heart chambers and covers the heart valves.
- A heart attack occurs when the blood flow to the heart is blocked, causing damage to the heart muscle, whereas a stroke occurs when the blood flow to the brain is blocked, causing damage to the brain tissue.
Circulatory System
- The lymphatic system plays a crucial role in the circulatory system by:
- Returning interstitial fluid to the bloodstream, helping to maintain blood pressure and volume.
- Aiding in the removal of waste products from the body.
- Providing immune function by producing and transporting immune cells, such as lymphocytes.
