PBS heart study

QuestionAnswer
Aorta the main artery of the body, supplying oxygenated blood to the circulatory system.
Left Ventricle one of the four chambers of the heart,the left ventricle pumps blood full of oxygen out to the body.
Right Ventricle one of the four chambers of the heart,he right ventricle pumps blood low in oxygen to the lungs. In the lungs, the blood then gets a "refill" of oxygen.
Left Atrium one of the four chambers of the heart. The left atrium receives blood full of oxygen from the lungs and then empties the blood into the left ventricle.
Right Atrium one of the four chambers of the heart. The right atrium receives blood low in oxygen from the body and then empties the blood into the right ventricle.
Coronary Artery Coronary arteries supply blood to the heart muscle. Like all other tissues in the body, the heart muscle needs oxygen-rich blood to function.
Apex The apex of the heart is at the tip of the left and right ventricles. It sits on the opposite side of this organ from the base of the heart.
Superior Vena Cava a large vein carrying deoxygenated blood into the heart. There are two in humans, the inferior vena cava (carrying blood from the lower body) and the superior vena cava (carrying blood from the head, arms, and upper body).
Inferior Vena Cava a large vein carrying deoxygenated blood into the heart. There are two in humans, the inferior vena cava (carrying blood from the lower body) and the superior vena cava (carrying blood from the head, arms, and upper body).
Pulmonary Artery the artery carrying blood from the right ventricle of the heart to the lungs for oxygenation.
Pulmonary Veins a vein carrying oxygenated blood from the lungs to the left atrium of the heart.
Cordae Tendinea any of the delicate tendinous cords that are attached to the edges of the atrioventricular valves of the heart and to the papillary muscles and serve to prevent the valves from being pushed into the atrium during the ventricular contraction.
Papillary Muscles he papillary muscles of the heart are pillar-like muscles seen within the cavity of the ventricles, attached to their walls. They have an integral role in proper cardiac valvular function.
Septum a partition separating two chambers, such as that between the nostrils or the chambers of the heart.
Tricuspid Valve The tricuspid valve sits between the heart's two right chambers. The tricuspid valve consists of three thin flaps of tissue (called cusps, or leaflets).
Bicuspid/Mitral Valve The mitral valve is also known as the bicuspid valve. This is one of the heart's four valves that help prevent blood from flowing backward as it moves through the heart.
Aortic Semilunar Valve A semilunar valve is the heart valve at the base of the aorta and the pulmonary artery, and consisting of cusps or flaps that prevent the backflow of the blood during systole.
Pulmonary Semilunar Valve A semilunar valve is the heart valve at the base of the aorta and the pulmonary artery, and consisting of cusps or flaps that prevent the backflow of the blood during systole.
Brachiocephalic Artery The brachiocephalic artery, brachiocephalic trunk, or more commonly referred to clinically as the innominate artery, is one of the three great vessels of the aortic arch that supplies blood to the head, neck and upper extremities.
