1.
Collagenous structures that connect AV valve leaflets to ventricular muscles
2.
Atrioventricular valve with two leaflets, best heard at the cardiac apex, also called the bicuspid valve
3.
Elastic artery that gives rise to the brachiocephalic trunk, left common carotid, and left subclavian arteries
4.
Chamber that receives oxygenated blood from the pulmonary veins prior to ventricular filling
5.
Chamber that generates pressure sufficient for pulmonary circulation but has thinner myocardium than its left-sided counterpart
6.
Valve auscultated best at the 5th intercostal space, left sternal border, separating right atrium and ventricle
7.
Ventricular muscles that contract to maintain tension on AV valve leaflets during systole
8.
Muscular structure separating the right and left cardiac chambers, containing bundle branches allowing for ventricular electrical conduction
9.
Chamber that receives systemic venous return via the superior and inferior vena cava
10.
Thin endothelial lining continuous with vascular endothelium covering chambers and valves
11.
Semilunar valve located between the right ventricular outflow tract and pulmonary trunk
12.
Vessel system formed by superior and inferior components draining into the right atrium
13.
Thick cardiac muscular layer responsible for systolic contraction, supplied primarily by the coronary arteries
14.
Chamber with the thickest myocardium, responsible for maintaining systemic arterial pressure
15.
Valve whose closure contributes to S2 together with the pulmonary valve
