EXPLAINATION:-

• The heart is a muscular organ covered by a double membrane called pericardium.
• Functions of the human heart include pumping blood throughout the body. However, there are various types of circulation within the body. Primarily, two types of circulation exist, namely pulmonary circulation and systemic circulation.
• Types of Circulation

✔Pulmonary circulation is a portion of circulation responsible for carrying deoxygenated blood away from the heart, to the lungs and then brings oxygenated blood back to the heart.

✔Systemic circulation is another portion of circulation where the oxygenated blood is pumped from the heart to every organ and tissue in the body, and then back again to the heart.

✔Coronary circulation is the most essential portion of the circulation, where oxygenated blood is supplied to the heart. This is important as the heart is responsible for supplying blood throughout the body. And organs like the brain need a steady flow of fresh, oxygenated blood to ensure functionality.

• The human heart is about the size of our own fist and is mainly divided into four chambers namely two ventricles and two atria. The ventricles are the chambers that pump blood and atrium are the chambers that receive blood. Among which both right atrium and ventricle make up the “right heart,” and the left atrium and ventricle make up the “left heart.”
• The right and the left region of the heart are separated by a wall of muscle called the septum. The right ventricle pumps the blood to the lungs for re-oxygenation through the pulmonary arteries. The right semilunar valves close and prevent the blood from flowing back into the heart. Then, the oxygenated blood is received by the left atrium from the lungs via the pulmonary veins.

Answer 2

Answer:

The heart is divided into four chambers consisting of two atria and two ventricles; the atria receive blood, while the ventricles pump blood. The right atrium receives blood from the superior and inferior vena cavas and the coronary sinus; blood then moves to the right ventricle where it is pumped to the lungs.
