Ventricle (heart)
Ventricle (heart)
The ventricle (pronounced: ven-tri-kul) is one of the two main chambers of the heart that pump blood out of the heart to the body. The heart has two ventricles - the left ventricle and the right ventricle.
Etymology
The term 'ventricle' is derived from the Latin word 'ventriculus', which means 'little belly'. This is due to the rounded shape of the ventricles.
Function
The right ventricle receives deoxygenated blood from the right atrium and pumps it to the lungs through the pulmonary artery. The left ventricle, on the other hand, receives oxygenated blood from the left atrium and pumps it to the rest of the body through the aorta.
