Study Notes
Heart Structure
- Blood enters the heart through two atria: left atrium (oxygenated blood from lungs) and right atrium (deoxygenated blood from body).
- Blood is pumped out of the heart by two ventricles: left ventricle (to body) and right ventricle (to lungs).
- The septum is the wall that separates the left and right sides of the heart.
Blood Flow Dynamics
- Left side processes oxygenated blood, received from the lungs after oxygenation, and pumps it to the body.
- Right side processes deoxygenated blood, received from the body, and pumps it to the lungs for reoxygenation.
- Pulmonary arteries carry deoxygenated blood from the right ventricle to the lungs.
- Pulmonary veins return oxygenated blood from the lungs to the left atrium.
Major Blood Vessels
- Aorta: transports oxygenated blood from the left ventricle to the entire body.
- Superior vena cava: brings deoxygenated blood from the head and upper body to the right atrium.
- Inferior vena cava: carries deoxygenated blood from the lower body to the right atrium.
- Blood becomes deoxygenated in body capillaries where oxygen is delivered to tissues.
Oxygenation and Deoxygenation Process
- Lung capillaries convert deoxygenated blood from the body into oxygenated blood through respiration.
- Body capillaries convert oxygenated blood from the lungs into deoxygenated blood as oxygen is utilized by tissues.
Heart Valve Function
- Properly functioning heart valves ensure one-way blood flow; malfunction can lead to backward flow, affecting circulation efficiency.
Circulation Types
- Pulmonary circulation: the movement of blood between the heart and lungs for oxygenation.
- Systemic circulation: the movement of oxygenated blood from the heart to rest of the body and back.
