    Study Notes

    Heart Structure and Function

    • The left anterior descending artery (anterior interventricular) supplies blood to the anterior wall of the left ventricle.
    • The aortic arch is the curved segment of the aorta from which the major arteries branch.
    • The aortic semilunar valve prevents backflow from the aorta into the left ventricle during diastole.
    • The apex is the tip of the heart, located at the bottom of the left ventricle.
    • The ascending aorta carries oxygenated blood away from the heart to the body.
    • The atrioventricular node (AV node) is responsible for relaying electrical impulses from the atria to the ventricles.
    • The base of the heart is the upper part where the great vessels emerge.
    • The brachiocephalic artery is the first branch of the aortic arch, supplying blood to the right arm and head.
    • Chordae tendineae are fibrous strings that connect the heart valves to the papillary muscles, ensuring valve closure.
    • The circumflex artery supplies blood to the left atrium and the lateral and posterior walls of the left ventricle.
    • The descending aorta is the continuation of the aorta as it travels downward through the thoracic and abdominal cavities.
    • The endocardium is the inner lining of the heart chambers and valves.
    • The visceral pericardium is the inner layer of the pericardium, covering the heart surface.
    • The fossa ovalis is a remnant of the fetal foramen ovale, allowing blood to bypass the non-functioning lungs in the fetus.
    • The great cardiac vein drains blood from the heart muscle and returns it to the right atrium via the coronary sinus.
    • The inferior vena cava carries deoxygenated blood from the lower body to the right atrium.
    • The interventricular septum separates the left and right ventricles, preventing mixing of oxygenated and deoxygenated blood.
    • The left atrioventricular (bicuspid) valve prevents backflow from the left ventricle to the left atrium.
    • The left atrium receives oxygenated blood from the lungs via the pulmonary veins.
    • The left auricle is a small pouch attached to the left atrium, increasing its volume.
    • The left bundle branches conduct electrical impulses to the left ventricle.
    • The left common carotid artery supplies blood to the left side of the head and neck.
    • The left coronary artery branches into the left anterior descending and circumflex arteries.
    • The left pulmonary artery carries deoxygenated blood from the right ventricle to the left lung.
    • The left pulmonary veins return oxygenated blood from the left lung to the left atrium.
    • The left subclavian artery supplies blood to the left arm.
    • The left ventricle pumps oxygenated blood to the body through the aorta.
    • The ligamentum arteriosum is the remnant of the ductus arteriosus, connecting the pulmonary trunk and aorta in the fetus.
    • The myocardium is the thick middle muscle layer of the heart, responsible for contraction.
    • Papillary muscles anchor the chordae tendineae and assist in valve function.
    • The posterior descending artery (interventricular) supplies the inferior wall of the heart.
    • The pulmonary semilunar valve prevents backflow into the right ventricle during diastole.
    • The pulmonary trunk carries deoxygenated blood from the right ventricle to the lungs.
    • Purkinje fibers conduct impulses throughout the ventricles, coordinating contraction.
    • The right atrioventricular (tricuspid) valve prevents backflow into the right atrium.
    • The right atrium receives deoxygenated blood from the body through the superior and inferior vena cavae.
    • The right auricle increases the volume of the right atrium.
    • The right bundle branches conduct electrical impulses to the right ventricle.
    • The right common carotid artery supplies blood to the right side of the head and neck.
    • The right coronary artery supplies blood to the right atrium and right ventricle.
    • The marginal artery supplies blood to the colon, branching from the mesenteric arteries.
    • The right subclavian artery supplies blood to the right arm.
    • The right ventricle pumps deoxygenated blood to the lungs through the pulmonary trunk.
    • The sinoatrial node (SA node) is the heart's natural pacemaker, initiating electrical impulses for heartbeats.
    • The superior vena cava returns deoxygenated blood from the upper body to the right atrium.
    • The right and left brachiocephalic veins drain blood from the head and arms into the superior vena cava.
    • The esophagus is a muscular tube connecting the throat and stomach, located posterior to the heart.
    • The trachea is the windpipe, conducting air to and from the lungs, situated anterior to the esophagus.
    • The coronary sinus collects deoxygenated blood from the heart muscle and drains into the right atrium.
    • The middle cardiac vein drains blood from the posterior part of the heart directly into the coronary sinus.
