Study Notes

Cardiovascular Anatomy

Aorta: The main arterial trunk that distributes oxygenated blood from the heart to the body via branch arteries.
Superior Vena Cava: Second largest vein; returns deoxygenated blood from the upper body to the right atrium of the heart.
Inferior Vena Cava: Largest vein in the body; carries deoxygenated blood from lower body regions to the right atrium.

Heart Chambers

Right Atrium: Receives deoxygenated blood from the superior and inferior vena cavae and the coronary sinus.
Left Atrium: Receives oxygenated blood from the pulmonary veins; sends blood into systemic circulation.
Right Ventricle: Pumps deoxygenated blood to the lungs for oxygenation.
Left Ventricle: Delivers oxygenated blood into the aorta for systemic distribution.

Pulmonary Circulation

Left Pulmonary Artery: Transports deoxygenated blood from the right ventricle to the left lung.
Right Pulmonary Artery: Carries deoxygenated blood from the right ventricle to the right lung.
Right Pulmonary Vein: Returns oxygenated blood from the right lung to the left atrium.
Left Pulmonary Vein: Transports oxygenated blood from the left lung back to the left atrium.

Heart Valves

Pulmonary Semilunar Valve: Located between the right ventricle and the pulmonary artery; regulates blood flow to the lungs.
Tricuspid Valve: Prevents backflow of blood from the right ventricle to the right atrium; composed of three membranous flaps.
Bicuspid (Mitral) Valve: Guards the opening between the left atrium and left ventricle; prevents backflow into the atrium.
Aortic Semilunar Valve: Positioned between the left ventricle and the aorta; facilitates blood flow into systemic circulation.

Structural Features

Septum: Muscular wall that divides the heart into right and left chambers, ensuring separation of oxygenated and deoxygenated blood.
Visceral Pericardium: Protective layer covering the heart's surface.
Myocardium: Thick muscular middle layer responsible for heart contractions.
Fossa Ovalis: Remnant of the foramen ovale from the fetal heart, marking a significant feature in adult hearts.
