Blood是从哪里来的

Blood in the human body originates from hematopoietic stem cells in the bone marrow, which can give rise to various blood cells such as plasma, platelets, and white blood cells. If abnormal blood findings are detected during examination, it is recommended to follow medical advice and receive timely treatment. The details are as follows:

The bone marrow is a soft, sponge-like substance typically located in the central part of human skeletal tissue. Hematopoietic stem cells in the bone marrow produce most of the body's blood cells, although other organs involved in blood formation include the spleen and liver. In adults, the majority of bone marrow is found in the pelvic bones, chest, spine, and other skeletal areas such as the hip bones, ribs, and vertebrae. Human blood cells develop from hematopoietic stem cells in the bone marrow through stages of proliferation and differentiation, eventually maturing into red blood cells, white blood cells, platelets, and other types of blood cells.

In daily life, maintaining a balanced diet and consuming appropriate amounts of vitamin- and protein-rich foods such as citrus fruits and eggs can contribute to overall health.
