Chapter 16&17 Heart function and Anatomy – Flashcards

Semilunar valve located between the left ventricle and aorta.

Cuspid valves located between the atria and ventricles; include the tricuspid and bicuspid (mitral) valves.

Upper chamber of the heart that receives blood from veins.

The atrioventricular valve between the left atrium and left ventricle; also called the mitral valve.

The study of the heart

Tough fibrous bands of connective tissue that attach the cusps of the AV valves to the walls of the ventricles of the heart.

Right and left coronary arteries deliver oxygenated blood to the heart muscles.

Inner lining of the heart wall.

Outer layer of the heart; forms part of the pericardium.

bicuspid valve.

Heart muscle.

Slinglike serous membrane that partially encloses the heart; supports the weight of the heart.

Area of the anterior chest that overlies the heart.

are networks of fibers that receive conductive signals originating at the atrioventricular node (AVN), and simultaneously activate the left and right ventricles by directly stimulating the ventricular myocardium

each of a pair of valves in the heart, at the bases of the aorta and the pulmonary artery, consisting of three cusps or flaps that prevent the flow of blood back into the heart

valve that is situated at the opening of the right atrium of the heart into the right ventricle and that resembles the mitral valve in structure but consists of three triangular membranous flaps—called also right atrioventricular valve

a hollow part or cavity in an organ, in particular. •each of the two main chambers of the heart, left and right. •each of the four connected fluid-filled cavities in the center of the brain.
