Does Blood Undergo Metabolism?

Blood is part of the human circulatory system, often associated with metabolism. Metabolism refers to the conversion process of substances and energy within organisms, encompassing material metabolism and energy metabolism. As a component of the circulatory system, blood primarily functions to transport oxygen, nutrients, and metabolites, sustaining the normal physiological functions of various organs and tissues in the human body. During this process, blood itself undergoes metabolism.

Metabolites in blood include carbon dioxide, lactic acid, urea, etc. These metabolites are waste products generated during human metabolism and need to be transported by blood to organs such as the liver and kidneys for excretion. The metabolic cycle of blood cells is relatively long, usually requiring approximately three months to complete a full cycle. This implies that if the body is exposed to toxic and harmful substances, it will take at least three months to renew the metabolites in the blood, thereby reducing damage to the body.

In daily life, we need to avoid exposure to toxic and harmful substances. If we must come into contact with these substances, we should take protective measures to minimize harm to our bodies.
