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.
