Heart Flashcards
Superior Vena Cava
vein that carries deoxygenated blood from the upper half of the body to the heart’s right atrium. It is located in the anterior right superior mediastinum
Inferior Vena Cava
large vein that carries de-oxygenated blood from the lower half of the body into the right atrium of the heart
Right Atrium
the right upper chamber of the heart that receives blood from the venae cavae and coronary sinus
Tricuspid Valve
(trahy-kuhs-pid)
a valve of the heart, composed of three flaps, that keeps blood from flowing backward from the right ventricle into the right atrium.
Right Ventricle
is one of four chambers (two atria and two ventricles) in the human heart. It receives deoxygenated blood from the right atrium via the tricuspid valve, and pumps it into the pulmonary artery via the pulmonary valve and pulmonary trunk.
Pulmonary Valve
a semilunar valve between the right ventricle and the pulmonary artery; prevents blood from flowing from the artery back into the heart
Pulmonary Artery
artery that carries deoxygenated blood from the right ventricle of the heart to the lungs
Pulmonary Vein
vein that carries oxygenated blood from the lungs to the left atrium of the heart
Left Atrium
the left upper chamber of the heart that receives blood from the pulmonary veins
Bicuspid Valve
A valve of the heart, composed of two triangular flaps, that is located between the left atrium and left ventricle and regulates blood flow between these chambers
Left Ventricle
the chamber on the left side of the heart that receives arterial blood from the left atrium and pumps it into the aorta
Aortic Valve
a semilunar valve between the left ventricle and the aorta; prevents blood from flowing from the aorta back into the heart
Aorta
(ay-or-tah)
The main artery of the body, supplying oxygenated blood to the circulatory system
Mediastinum
(mee-dee-a-stahy-nuhm)
the partition separating the right and left thoracic cavities, formed of the two inner pleural walls, and, in humans, comprising all the viscera of the thorax except the lungs.
