Study Notes
Major Veins
- Superior Vena Cava: Carries deoxygenated blood from the upper body into the heart.
- Inferior Vena Cava: Transports deoxygenated blood from the lower body to the heart.
Major Arteries
- Aorta: Main artery distributing oxygenated blood throughout the body.
- Pulmonary Artery: Channels blood from the right ventricle to the lungs for oxygenation.
Cardiac Chambers
- Right Atrium: Receives deoxygenated blood from the vena cavae; acts as a holding chamber.
- Right Ventricle: Pumps oxygen-poor blood to the lungs for re-oxygenation.
- Left Atrium: Holds oxygenated blood returning from the lungs; initiates blood flow to the left ventricle.
- Left Ventricle: Pumps oxygen-rich blood to the body; the strongest chamber of the heart.
Valves
- Tricuspid Valve: Prevents backflow of blood into the right atrium during ventricular contraction.
- Bicuspid (Mitral) Valve: Regulates blood flow from the left atrium to the left ventricle.
- Aortic Valve: Prevents blood regurgitation from the aorta into the left ventricle; ensures proper blood flow during heart contractions.
- Pulmonary Valve: Opens during ventricular contraction, allowing blood to flow into the pulmonary artery; closes when pressure drops.
Pulmonary Circulation
- Right Pulmonary Veins: Transport oxygenated blood from the lungs to the left atrium.
- Left Pulmonary Veins: Carry oxygenated blood from the lungs back to the left atrium.
General Cardiac Function
- Diastole: Period where the ventricles relax and fill with blood.
- Systole: Phase of heart contraction, pushing blood into circulation.
