Four functions of the spleen: 1, hematopoietic function; 2, blood storage function; 3, blood filtration function; 4, immune function.
The spleen is one of the traditional Chinese medicine organs of the human body, which plays a very important role in the body. How much do you know about the four functions of the spleen? Now let’s give you a detailed introduction.
Hematopoietic function: the spleen contains a small amount of hematopoietic stem cells. When the body goes in and out of the state of severe ischemia, the spleen can restore hematopoietic function and produce red blood cells, granulocytes and platelets.
Blood storage function: The blood storage capacity of the human spleen is small, about 40 ml of blood can be stored, mainly in the blood sinus. When the spleen is enlarged, its blood storage also increases. When the body needs blood, the contraction of the spleen smooth muscle can drain the stored blood into the blood circulation, and the spleen will shrink immediately.
Blood filtering function: The spleen is also an effective blood filtering organ. When bacteria, foreign bodies, antigen antibody complexes and aged blood cells in the blood flow through the spleen, they are swallowed and digested by a large number of macrophages.
Immune function: pathogens invading blood, such as bacteria, Plasmodium and schistosome, can cause the spleen’s immune response, and its volume and partial structure can also change.
The spleen is the largest peripheral lymphatic organ in the human body. The function of the spleen is to absorb and absorb the essence in the stomach, and it is the capacitive filter of human.
