Study Notes

Heart Anatomy and Function

Left Ventricle: Essential for pumping oxygen-rich blood through the aorta to supply the entire body.
Right Atrium: Receives deoxygenated blood coming back from the body, acting as the heart's entry chamber for used blood.
Right Ventricle: Responsible for pumping deoxygenated blood into the lungs for oxygenation, crucial for the respiratory circulation.
Aorta: The body's largest artery that ensures the distribution of oxygenated blood from the left ventricle to the various organs and tissues.
Left Atrium: Functions as the receiving chamber for incoming oxygenated blood from the lungs via pulmonary veins.

Major Blood Vessels and Circulatory Pathways

Superior Vena Cava: Carries deoxygenated blood from the upper part of the body to the right atrium, facilitating blood return to the heart.
Inferior Vena Cava: Similar to the superior counterpart, but specifically transports blood from the lower regions of the body to the right atrium.
Pulmonary Artery: Unique for carrying deoxygenated blood from the right ventricle to the lungs, involved in the pulmonary circuit for gas exchange.
Pulmonary Vein: Responsible for transporting oxygenated blood from the lungs back to the left atrium, completing the oxygenation cycle.

Heart Valves

Mitral Valve: Positioned between the left atrium and left ventricle, ensures one-way blood flow and prevents backflow during ventricular contraction.
Aortic Valve: Located at the exit of the left ventricle, allowing blood flow into the aorta while preventing backflow into the ventricle.
Pulmonary Valve: Found between the right ventricle and pulmonary arteries, it regulates blood flow to the lungs and prevents backflow into the ventricle.
Tricuspid Valve: This valve resides between the right atrium and right ventricle, ensuring blood moves in one direction and prevents backflow during contraction.
