Unidirectional blood flow is essential and the primary function of heart valves. Malformation and dysfunction of these complex structures result in potentially fatal pathologies. In this chapter, the formation, anatomy, and histology of the four cardiac valves will be described. These four cardiac ...
Heart valves separate atria from ventricles, and ventricles from great vessels. The valves incorporate two or three leaflets (cusps) around the atrioventricular orifices and the roots of great vessels. The cusps are pushed open to allow blood flow in one direction, and then closed to seal the...
the inner layer of the heart, and has three strong cusps or flaps, hence its name. This valve is one of the two atrioventricular valves in the heart, the other being themitral valve, also known as thebicuspid valve. These
There is a one-way flow of blood through the heart, which is maintained by a set of four valves (tricuspid, bicuspid, pulmonary, and aortic). The tissues of the heart are supplied with nourishment and oxygen by a separate vascular supply committed only to the heart; the arterial supply ...
The flow of blood through the heart is partially regulated by unidirectional valves that exist between the atria and ventricles. The valves between each atrium and ventricle are referred to as atrioventricular valves (right and left). The two valves that regulate the flow of blood from the ...
When blood leaves each chamber of the heart, it passes through a valve that is designed to prevent the backflow of blood. There are four valves within the heart: Mitral valve between the left atrium and left ventricle The tricuspid valve between the right atrium and right ventricle The aortic...
Chambers and Valves The heart is divided into a right and a left heart, each subdivided into two chambers: an upper chamber called an atrium (or auricle) and a lower chamber called a ventricle. The two atria act as receiving chambers for blood entering the heart, while the more muscular ...
Learn about the anatomy of the heart and how its chambers, valves, and vessels work together to maintain effective blood circulation throughout the body to sustain life.

Heart Valves Blood flows through the heart in one direction: from the atria to the ventricles and out the great arteries leaving the superior aspect of the heart. Four valves enforce the one-way traffic. They open and close in response to differences in blood pressure. ...
