Study Notes
Heart Function
- The heart pumps blood throughout the body, ensuring oxygen and nutrients reach all tissues.
Heart Chambers and Blood Separation
- The interatrial septum divides the left and right atria.
- The interventricular septum separates the left and right ventricles.
Blood Oxygenation
- The left side of the heart contains oxygenated blood.
- The right side of the heart contains deoxygenated blood.
Major Blood Vessels
- Superior vena cavae and inferior vena cavae bring deoxygenated blood to the right atrium.
- The pulmonary trunk transports deoxygenated blood from the right ventricle to the lungs.
- Pulmonary veins carry oxygenated blood from the lungs to the left atrium.
- The aorta distributes oxygenated blood from the left ventricle to the body.
Function of Each Chamber
- The right atrium receives blood from the vena cavae.
- The left atrium receives blood from the pulmonary veins.
- The right ventricle pumps blood to the pulmonary trunk.
- The left ventricle pumps blood to the aorta.
Blood Oxygen Levels
- The right atrium contains low-oxygen (deoxygenated) blood.
- The right ventricle also contains deoxygenated blood.
- The left atrium holds high-oxygen (oxygenated) blood.
- The left ventricle likewise contains oxygenated blood.
Blood Return Functions
- Superior and inferior vena cavae return deoxygenated blood from systemic circulation to the right atrium.
- Left and right pulmonary veins return oxygenated blood from the lungs to the left atrium.
Pulmonary Circuit Functions
- The pulmonary trunk takes deoxygenated blood to the pulmonary arteries, leading to the lungs.
- Left and right pulmonary arteries transport deoxygenated blood to the lungs.
Systemic Circuit Function
- The aorta carries oxygenated blood from the left ventricle to systemic circulation.
Valves and Their Functions
- The tricuspid valve prevents backflow of blood into the right atrium.
- The bicuspid valve (mitral valve) prevents backflow of blood into the left atrium.
- The pulmonary semilunar valve prevents backflow of deoxygenated blood into the right ventricle.
- The aortic semilunar valve prevents backflow of oxygenated blood into the left ventricle.
