Bone Marrow Facts Functions and Transplants Biology Diagrams The anatomy of bone marrow is organized into two types: red marrow and yellow marrow, each serving distinct purposes. Below is a detailed description of the structure and organization of bone marrow. Types of Bone Marrow. There are two main types of bone marrow, each with different cellular compositions and functions: Bone Marrow Structure . Bone marrow is separated into a vascular section and non-vascular sections. The vascular section contains blood vessels that supply the bone with nutrients and transport blood stem cells and mature blood cells away from the bone and into circulation. The non-vascular sections of the bone marrow are where hematopoiesis or
Bone marrow is a semi-solid tissue found within the spongy (also known as cancellous) portions of bones. [2] In birds and mammals, bone marrow is the primary site of new blood cell production (or haematopoiesis). [3] It is composed of hematopoietic cells, marrow adipose tissue, and supportive stromal cells.In adult humans, bone marrow is primarily located in the ribs, vertebrae, sternum, and
Bone Marrow Biology Diagrams
Learn about the anatomy and physiology of bone marrow, the soft tissue in the bone cavities that produces blood cells. Find out how bone marrow can be affected by disease, infection, or radiation, and how bone marrow transplant can help.
Hematopoietic cords (histological slide) Red marrow is most abundant in all skeletal structures from intrauterine life up until around the 5th year of life. As time progresses, red marrow is restricted to the central flat bones (i.e. cranial bones, clavicle, sternum, ribs, scapula, vertebrae, and pelvis) and the proximal ends of the proximal long bones of the upper and lower limbs.
Structural organization of the bone marrow and its role in ... Biology Diagrams
Anatomy . Bone marrow is considered the fourth largest organ in the body by weight, accounting for 4% to 5% of a person's total body weight. It is a spongy, jelly-like tissue located in the center of certain large bones, including those in the hips and spine.
