Articular cartilage
D
Periosteum
Verified step by step guidance
1
Understand the function of hematopoietic tissue: Hematopoietic tissue is responsible for the production of blood cells, including red blood cells, white blood cells, and platelets. This process is called hematopoiesis.
Identify the location of red bone marrow: In adults, red bone marrow, which contains hematopoietic tissue, is primarily found in the epiphysis (the ends of long bones) and in flat bones such as the sternum and pelvis.
Differentiate between red and yellow bone marrow: Yellow bone marrow, found in the diaphysis (shaft of long bones), primarily stores fat and does not play a significant role in hematopoiesis.
Eliminate incorrect options: Articular cartilage and periosteum are not involved in hematopoiesis. Articular cartilage covers the ends of bones at joints, and the periosteum is a fibrous membrane covering the outer surface of bones.
Conclude that the correct answer is red bone marrow in the epiphysis, as this is where hematopoietic tissue is primarily located in adult long bones.
