Parts of human heart and its role and functions are explained below in details.
Explanation:
The heart is a muscular organ about the dimension of a hand, positioned just back and slightly left of the breastbone. The heart elevates blood through the system of veins and arteries called the cardiovascular arrangement.
The heart has four chambers:
- The right atrium receives serum from the veins and elevates it to the right ventricle.
- The left side atrium carries oxygenated blood from the lungs and elevates it to the left ventricle.
- The right ventricle takes blood from the right atrium and elevates it to the lungs, where oxygen is filled.
- The left ventricle elevates oxygen-rich serum to the remainder of the body. The left ventricle strong contractions produce our blood pressure.
