These openings are periodically shut and open by the heart valves, depending on the phase of the heart cycle. Although there are a lot of structures in the heart diagrams, you shall not worry, we’ve got them all covered for you in these articles and video tutorials. Be sure to check...
The wall of the heart consists of three layers of tissue:Epicardium — protective layer mostly made of connective tissue.Myocardium — the muscles of the heart.Endocardium — lines the inside of the heart and protects the valves and chambers....
aortic and pulmonary valvescoronary sinusright and left coronary arteriesventricleThe heart starts as a single tube. In the course of the first three months of intra-uterine life, it develops into the two atria and ventricles, connected to the appropriate veins and arteries. The partitions (septa...
This review will discuss the heart's anatomy, focusing on the chambers, great vessels, and valves. The human heart is located in the mediastinum, a cavity between the right and left lungs. It is positioned slightly to the left of the center of the chest
The heartbeat period lasts about 2 s. Large anterior- and posterior-going arteries, which branch extensively to supply various body organs, issue from the heart. Semilunar valves, located at the juncture of each artery with the heart, prevent backflow of blood into the heart when it relaxes....
The heart valves are uniquely designed gates that promote the unidirectional flow of blood through the heart. They are attached to special muscular appendages that help to keep them stable. This article aims to explore the embryology and gross anatomy of the heart valves. Additional discussion ...
Blood flows through the heart in 1 direction, moving from the right side of the heart, through the lungs , and then returning to the left side of the heart, where it is pumped out to the rest of the body. As blood moves through the heart, 4 important valves prevent backflow. The ...

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. ...
