Study Notes
Cardiovascular System
- Smooth muscles are found in the walls of blood vessels in the cardiovascular system
- The heart's function in the cardiovascular system is to pump blood throughout the body
- The lymphatic system contains lymph in the cardiovascular system
- Capillaries exchange nutrients, dissolved gases, and wastes with tissues in the cardiovascular system
- There are two circuits in the blood vascular system: pulmonary and systemic
- The pulmonary circuit oxygenates the blood in the cardiovascular system
Heart Structure
- The right atrium receives deoxygenated blood from the superior vena cava, inferior vena cava, and coronary sinus
- The function of the myocardium is to contract and pump blood throughout the body
- The epicardium is the outermost layer of the heart wall, composed of simple squamous epithelium
- Arteries and veins have different physiological structures due to differences in blood pressure
- The purpose of the pericardial fluid is to reduce friction between the heart and surrounding tissues
Blood Vessels
- Arteries transport blood away from the heart in the cardiovascular system
- The exchange network of capillaries allows for the exchange of nutrients, dissolved gases, and wastes with tissues
- Lymphatics in the cardiovascular system provide a one-way drainage system that reunites with the blood vascular system
- The pulmonary and systemic circuits work in series in the cardiovascular system
- Major arteries are situated according to their function to avoid damage
- Capillaries surround blood capillaries and drain excess fluid in the cardiovascular system
Heart Function
- The heart functions as a pump in the cardiovascular system
- The left ventricle has thicker walls compared to the right ventricle due to the higher pressure required to pump blood to the entire body
- The fibrous pericardium is the outermost layer of the pericardium, providing protection and support to the heart
- The cardiovascular system is made up of connective tissues and cells such as epithelial and muscle cells
- Epithelial cells form barriers between blood and the walls of the vascular system to prevent coagulating and clotting of blood inside blood vessels
