Bone Marrow

Bone marrow is a soft, spongy tissue found in the cavities of bones. It is a crucial part of the body's hematopoietic system, responsible for the production of blood cells. There are two types of bone marrow: red and yellow. Red bone marrow is primarily involved in the production of blood cells, while yellow bone marrow is mainly composed of fat cells.

Functions of Bone Marrow

The main functions of bone marrow include:

• Production of red blood cells (erythropoiesis)
• Production of white blood cells (leukopoiesis)
• Production of platelets (thrombopoiesis)

Types of Bone Marrow

There are two main types of bone marrow:

1. Red Bone Marrow: Found in the cavities of spongy bone and is involved in the production of blood cells.
2. Yellow Bone Marrow: Found in the central cavities of long bones and consists mainly of fat cells.

Composition of Bone Marrow

Bone marrow is composed of various types of cells, including:

• Hematopoietic stem cells
• Red blood cells
• White blood cells
• Platelets
• Fat cells
