The function of the human spleen

The spleen is one of the mid-term immune organs and the largest lymphatic organ in the human body. The spleen has very important value and role in our body. When the spleen is damaged, everyone's body will have spleen and stomach dysfunction, and may even be affected by some other organs and tissues, so at this time they will face a decline in immunity.

The spleen is one of the central immune organs and the largest lymphoid organ in the human body. It grows in the upper left side of the abdominal cavity. Although it is protected by the 9th to 11th ribs in front, it is relatively brittle and easily injured.

The spleen is a hematopoietic organ in the fetus. After birth, its hematopoietic function is replaced by red bone marrow, but the spleen can still produce lymphocytes and other immunity-related cells and substances. It also filters the blood. Bacteria, viruses and other foreign matter that enter the human body are processed here and then eliminated by antibodies produced by T lymphocytes and B lymphocytes; aging red blood cells and platelets

Here it is destroyed and cleared. The spleen also performs necessary "repairs" on newly formed red blood cells and stores a large number of platelets. The spleen is like a sponge soaked in blood, storing a lot of blood. When the human body is in urgent need, the spleen contracts and squeezes out blood, so the spleen is also a small emergency blood bank.

Since the spleen is involved in the regulation of bone marrow hematopoiesis and the destruction and clearance of red blood cells and platelets, when a person has an enlarged spleen or hypersplenism due to illness, anemia and thrombocytopenic purpura will occur, and even massive bleeding may endanger the person's life.

The function of the adult spleen can be largely replaced by other tissues and organs. Therefore, when an enlarged spleen threatens human health, it can be removed, which will improve the condition. However, if the spleen is removed during infancy, it is often easy to cause a decrease in resistance.
