Right ventricle
Right Ventricle
The Right Ventricle (/ˈraɪt ˈvɛntrɪkəl/; from Latin ventriculus, meaning 'little belly') is one of the four chambers of the heart. It receives deoxygenated blood from the right atrium and pumps it under low pressure into the pulmonary artery, which carries it to the lungs for oxygenation.
Structure
The right ventricle is triangular in shape and extends from the tricuspid valve in the right atrium to the apex of the heart. Its anterior surface is sternocostal (toward the sternum and ribs), while its inferior surface is diaphragmatic (toward the diaphragm). Its posterior surface is formed by the septum, which it shares with the left ventricle.
Function
The primary function of the right ventricle is to pump deoxygenated blood to the lungs via the pulmonary artery. This process, known as pulmonary circulation, is crucial for oxygenating the blood.
Clinical Significance
Diseases of the right ventricle can lead to a variety of health problems. For example, pulmonary hypertension can cause right ventricular hypertrophy (enlargement of the heart muscle), which can in turn lead to heart failure. Other conditions that can affect the right ventricle include congenital heart disease, myocardial infarction (heart attack), and cardiomyopathy (disease of the heart muscle).
