Study Notes
Heart Anatomy and Function
- The heart consists of two sides, each with a ventricle and atrium.
- The left side of the heart is responsible for pumping deoxygenated blood to the lungs for oxygenation.
- The tricuspid valve separates the left atrium from the left ventricle.
- Semilunar valves play a crucial role in preventing the backflow of blood into the heart.
Blood Flow and Vessels
- The vena cava carries deoxygenated blood returning from the body to the heart.
- The pulmonary artery transports oxygenated blood from the right ventricle to the lungs.
- Oxygenated blood is then delivered to the body through the aorta.
- The main vein responsible for returning blood to the heart is the vena cava.
Circulatory System Overview
- The heart functions as a single pump, maintaining circulation throughout the body.
- Deoxygenated blood from the body enters the heart via the pulmonary vein, completing the blood flow cycle.
