What is the relationship between blood circulation and internal organs?

There is a close and complex relationship between blood circulation and internal organs. As an important substance for human life activities, blood circulation not only relies on the driving of the heart, but is also closely related to the physiological functions of the lungs, liver, spleen and other organs.

The heart is the power source of blood circulation. Through continuous contraction and relaxation, the heart promotes blood circulation in the blood vessels throughout the body, providing nutrients and oxygen to various organs and tissues, while taking away metabolic waste.

The lungs play an important role in blood circulation. The lungs inhale oxygen and expel carbon dioxide through breathing movements to achieve gas exchange. This process is essential for the oxygenation of the blood, ensuring that oxygen-rich blood is delivered throughout the body.

The liver has the function of storing blood and regulating blood volume. When the body needs it, the liver can release stored blood to maintain the stability of the circulatory system. In addition, the liver can also synthesize a variety of important plasma proteins, which play a key role in maintaining the normal composition and function of the blood.

The spleen is mainly responsible for filtering and storing blood in blood circulation. The spleen can remove harmful substances and aged red blood cells from the blood, while storing a portion of the blood for emergency use.

To sum up, there is a close connection between blood circulation and internal organs. The two complement each other and jointly maintain the life activities of the human body.
