Study Notes
Heart Anatomy Key Terms
-
Superior Vena Cava: Major vein delivering deoxygenated blood from the upper body to the right atrium.
-
Pulmonary Semilunar Valve: Cardiac valve that allows blood to flow from the right ventricle into the pulmonary artery, preventing backflow.
-
Right Atrium: Upper heart chamber that receives deoxygenated blood from the body via the superior and inferior vena cavae.
-
Right Ventricle: Lower heart chamber responsible for pumping deoxygenated blood to the lungs through the pulmonary artery.
-
Tricuspid Valve: One-way valve situated between the right atrium and right ventricle, controlling blood flow direction.
-
Fossa Ovalis: Oval depression in the right atrium, a remnant of the foramen ovale which allows fetal blood circulation.
-
Aortic Semilunar Valve: Valve that controls blood flow from the left ventricle into the aorta, preventing backflow into the ventricle.
-
Left Atrium: Chamber that receives oxygenated blood from the lungs via pulmonary veins.
-
Chordae Tendinae: Fibrous cords connecting heart valves to papillary muscles, preventing valve inversion during contraction.
-
Left Pulmonary Artery: Vessel that carries deoxygenated blood from the heart to the left lung for oxygenation.
-
Aorta: Largest artery in the body, distributing oxygenated blood from the left ventricle to all body parts.
-
Bicuspid (Mitral) Valve: Valve between the left atrium and left ventricle, regulating blood flow and preventing backflow.
-
Left Ventricle: Chamber that pumps oxygenated blood to the body through the aorta, generating the highest pressure.
-
Papillary Muscle: Muscle tissue in the ventricles that anchor the chordae tendinae, aiding in valve function.
-
Interventricular Septum: Thick muscular wall separating the left and right ventricles, maintaining pressure differences.
-
Apex: The pointed lower tip of the heart, located where the left ventricle meets the diaphragm.
-
Pectinate Muscles: Muscle ridges found in the auricles and along the wall of the right atrium, contributing to the heart's contraction efficiency.
