Study Notes
- Cardiovascular system: major functions (except): supplying oxygen-rich blood, eliminating carbon dioxide, transporting nutrients, and exchanging oxygen and carbon dioxide
- Heart: consists of four chambers - atria (upper) and ventricles (lower), separated by a septum
- Right side of the heart: involved in pulmonary circulation
- Left side of the heart: involved in systemic circulation
- Heart tissue layers: epicardium (outer), myocardium (middle with muscle tissue), endocardium (inner with endothelial cells), pericardium (sac-like structure with serous fluid)
- Heart valves: ensure one-way blood flow within the heart, prevent regurgitation
- Atrioventricular (AV) valves: separate atria from ventricles, cusped and leaflike
- Tricuspid valve: between right atrium and right ventricle
- Bicuspid valve (mitral): between left atrium and left ventricle
- Chordae tendineae and papillary muscles: support and control AV valve movement
- Semilunar valves: pulmonic and aortic valves, prevent blood from flowing back into ventricles
- Pulmonary circulation: oxygen-depleted blood from the body enters the right atrium, moves to the right ventricle, is pumped into the pulmonary artery, and reaches the lungs for oxygenation
- Systemic circulation: oxygen-rich blood from the left ventricle is pumped into the aorta and reaches all body cells and tissues
- Cardiac tissue layers and heart valves work together to maintain circulation.
