Schematic Diagram Of Pulmonary Circulation In Human Heart

By | June 17, 2022



The heart drives the entire circulatory system; it is responsible for the intake and output of oxygen. To understand how it works, it is important to understand the schematic diagram of pulmonary circulation in humans.

The human heart consists of four chambers – two atria, and two ventricles. The left and right atria are responsible for bringing oxygenated blood from the lungs and pumping it into the ventricles for circulation around the body. The right ventricle then pumps oxygen-depleted blood back to the lungs.

This process is known as pulmonary circulation. The right side of the heart takes oxygen-depleted or deoxygenated blood from the body and pumps it to the lungs, where it receives oxygen through the alveoli, tiny air sacs in the lungs. Once the blood is oxygenated, it is pumped back to the left side of the heart, which sends it around the body.

As oxygen-rich blood flows out of the left ventricle, it first passes through the aortic valve, then moves to the aorta, which is the largest artery in the body. From the aorta, the blood splits off into two branches: the pulmonary circulation and systemic circulation.

The pulmonary circulation pathway is what carries the oxygen-rich blood from the left side of the heart to the lungs, where the oxygen is then released into the alveoli. Once oxygen is released, the deoxygenated blood then follows the same route back to the heart.

Finally, the systemic circulation pathway brings oxygen-rich blood from the left side of the heart to every area of the body, including the arms, chest, legs, and internal organs. It provides oxygen to cells so they can function normally, and carries carbon dioxide away from the body's cells.

By understanding the schematic diagram of pulmonary circulation in humans, we gain a better understanding of how our heart works. This process keeps us alive and healthy, by ensuring our tissues and organs get the oxygen they need to function properly.
