Detailed explanation-1: -Your heart is divided into two separate pumping systems, the right side and the left side. The right side of your heart receives oxygen-poor blood from your veins and pumps it to your lungs, where the blood picks up oxygen and gets rid of carbon dioxide.

Detailed explanation-2: -It has two sides that match. The heart is symmetrical because there is symmetry in its design. This heart can be divided in half vertically where one half matches the other half. This line that divides the heart into matching parts is called the line of symmetry.

Detailed explanation-3: -There are four chambers that make up the heart – two on the left side and two on the right. The two small upper chambers are the atria. The two larger lower chambers are the ventricles. These left and right sides of the heart are separated by a wall of muscle called the septum.

Detailed explanation-4: -The heart doesn’t have corners it isn’t square. The human heart does have four chambers.

Detailed explanation-5: -The human heart can appear as a variety of shapes including elliptical, conical, round, valentine and trapezoidal (1). Within the thoracic cavity, the human heart exhibits greater left-side orientation, the apex is more tilted towards the left side of the body, compared to those of most quadruped mammals (3).
