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.
