haudekudoksen

Haudekudoksen, also known as bone marrow, is a spongy tissue found inside bones. It is a vital component of the body's circulatory and immune systems. There are two main types of bone marrow: red bone marrow and yellow bone marrow.

Red bone marrow is responsible for the production of blood cells, a process called hematopoiesis. It generates red blood cells, which carry oxygen throughout the body, as well as white blood cells, which fight infection, and platelets, which help in blood clotting. In infants, all bone marrow is red. As a person ages, much of the red bone marrow is replaced by yellow bone marrow.

Yellow bone marrow primarily consists of fat cells. While it does not produce blood cells, it can be converted back into red bone marrow if the body requires more blood cell production, such as during significant blood loss. Yellow bone marrow also serves as a storage site for fat, which can be used as an energy reserve.

The health of bone marrow is crucial for overall well-being. Conditions like leukemia and lymphoma directly affect bone marrow, impairing its ability to produce healthy blood cells. Bone marrow transplants are a medical procedure used to treat certain diseases by replacing diseased bone marrow with healthy marrow from a donor. This procedure can be life-saving for individuals with severe blood disorders.
