Answer: (B)

Verified step by step guidance

1. Understand the location and composition of red bone marrow: Red bone marrow is found in the cavities of certain bones, such as the pelvis, ribs, and sternum. It is composed of hematopoietic tissue, which is responsible for the production of blood cells.
2. Identify the types of blood cells produced: Red bone marrow is responsible for producing red blood cells (erythrocytes), white blood cells (leukocytes), and platelets (thrombocytes). These cells are essential for carrying oxygen, fighting infections, and clotting blood, respectively.
3. Recognize the process of hematopoiesis: Hematopoiesis is the process by which blood cells are formed in the red bone marrow. This involves the differentiation of hematopoietic stem cells into various types of blood cells.
4. Distinguish between red and yellow bone marrow: While red bone marrow is involved in blood cell production, yellow bone marrow primarily stores fat. As individuals age, some red bone marrow is converted to yellow bone marrow.
5. Connect the function of red bone marrow to overall health: The production of blood cells in red bone marrow is crucial for maintaining healthy oxygen levels, immune function, and blood clotting, highlighting its primary role in the body.
