The heart is a muscular organ that pumps blood to different parts of the body. The blood follows a specific pathway as it moves through the heart. Here are the steps the blood takes as it passes through the heart:

1. Right Atrium: The blood first enters the heart through the two large veins called the inferior and superior vena cava. These veins bring the deoxygenated blood from the body to the right atrium of the heart.

2. Right Ventricle: The blood then moves down to the right ventricle of the heart. The right ventricle is responsible for pumping the blood into the lungs to get oxygenated.

3. Lungs: The oxygenated blood from the lungs returns to the heart through the pulmonary veins and enters the left atrium of the heart.

4. Left Ventricle: The blood then passes from the left atrium down to the left ventricle. The left ventricle is responsible for pumping the oxygen-rich blood to the rest of the body.

5. Aorta: The oxygen-rich blood is pumped out of the heart through the aorta, which carries the blood to different parts of the body, including the brain, muscles, and organs.

This repeating cycle continues throughout a person’s lifespan, with the heart pumping an average of 2,000 gallons of blood per day.
