Verified step by step guidance

Understand the term '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 hematopoietic tissue in adults: In adults, hematopoietic tissue is primarily found in red bone marrow, which is located in specific regions of long bones and other bones.
Differentiate between red and yellow bone marrow: Red bone marrow is involved in blood cell production, while yellow bone marrow primarily stores fat and is found in the diaphysis (shaft) of long bones.
Locate red bone marrow in long bones: In adult long bones, red bone marrow is primarily located in the epiphyses (the ends of the bone), within the spongy bone tissue. This is where hematopoiesis occurs.
Exclude incorrect options: The periosteum is a fibrous membrane covering the bone and does not contain hematopoietic tissue. Articular cartilage at the bone ends provides smooth surfaces for joint movement but is not involved in hematopoiesis. Yellow bone marrow in the diaphysis is not hematopoietic tissue.
