HUMAN NUTRITION

Detailed explanation-1: -On each side of the wall, there is a small collecting chamber called an ‘atrium’, which leads into a large pumping chamber called a ‘ventricle’. There are four chambers: the left atrium and right atrium (upper chambers), and the left ventricle and right ventricle (lower chambers).

Detailed explanation-2: -Your heart has four separate chambers that pump blood. The chambers are called the right atrium, right ventricle, left atrium, and left ventricle. The right and left sides of the heart are separated by a muscular wall that prevents blood without oxygen from mixing with blood that has oxygen.

Detailed explanation-3: -The four-chambered heart provides an efficient solution by keeping oxygenated and non-oxygenated blood separate. The supply of oxygen to the body can also be improved by increasing how often the heart contracts.
