Document Summary
The cardiovascular system- lecture #1 and lecture #2. Anatomy and physiology review for the adult patient: the flow of blood from systemic system into the heart then back to systemic system. Pulmonary circulation start: right atrium tricuspid valve right ventricle pulmonary. Valve pulmonary trunk pulmonary arteries (x2 l/r) lungs pulmonary veins (l/r) left atrium. During this part, blood starts as deoxygenated, and then enters lungs and becomes oxygenated by mixing in with the capillaries. Systemic ciruclation start: left atrium mitral valve left ventricle aortic valve aorta goes to body superior/inferior vena cava right atrium. Oxygenated blood gets delivered to body systems via the aorta. Becomes deoxygenated and returns to the right atrium. Relies on left ventricle as pump: coronary circulation. Coronary vessels come off the aorta (first branches). The coronary veins drain directly into the right atrium (deoxygenated) Bronchial arteries bring oxygenated blood to the lungs.
