A ventricle is defined as a normal hollow chamber of the heart or the brain. The ventricles of the heart, which are separated by the interventricular septum, are the pumping chambers. 词汇:atria 心房(复数) atrium心房(单数) interatrial septum 房间隔 ventricles 心室(复数) ventricle 心室(单数)...
The interdependence of the right and left ventricles is clearly seen. The resetting of regional diastolic lengths may affect systolic and diastolic functions. Thus the structural and hemodynamic differences of these two pumping chambers determine the perfusion pressure-flow function integrity of the ...

The Human Heart The heart is a muscular organ that forms part of the cardiovascular system. The heart is located in the thoracic cavity, in the region called the mediastinum. The pumping action of the heart caused by depolarization ...
The atria, the receiving chambers of the heart, have relatively thin walls compared to the ventricles, the pumping chambers. The left ventricle has the thickest walls—nearly half an inch thick in an adult—because it must work the hardest to propel blood to the farthest reaches of the body...

On the inside, the heart is a four-chambered, hollow organ. It is divided into the left and right side by a wall called the septum. The right and left sides of the heart are further divided into two top chambers called the atria, which receive blood from the veins, and two bottom ch...
Regular check-ups with a doctor can also help detect any potential heart problems early on, which can improve the chances of successful treatment. In conclusion, the heart is a remarkable organ that is responsible for pumping blood throughout the body. It has four chambers, an electrical ...
2. Themyocardium, also known as myocardial muscle, is the middle and thickest of the heart’s three layers and consists of specialized cardiac muscle tissue. The constant contraction and relaxation of this muscle creates the pumping movement that maintains the flow of blood throughout the body. ...
The structure of the heart has four chambers: Atria: Upper two chambers of the heart. Ventricles: Lower two chambers of the heart. Heart Wall The structure of theheart wallconsists of three layers: Epicardium: The outer layer of the wall of the heart. ...
