Detailed explanation-1: -Bone marrow is the soft, fatty tissue inside of the bones in your body. Bone marrow contains cells that produce blood cells and platelets and it is responsible for making billions of new blood cells each day.

Detailed explanation-2: -The soft, spongy tissue that has many blood vessels and is found in the center of most bones. There are two types of bone marrow: red and yellow. Red bone marrow contains blood stem cells that can become red blood cells, white blood cells, or platelets.

Detailed explanation-3: -bone marrow, also called myeloid tissue, soft, gelatinous tissue that fills the cavities of the bones. Bone marrow is either red or yellow, depending upon the preponderance of hematopoietic (red) or fatty (yellow) tissue.

Detailed explanation-4: -Bone is made up of compact tissue (the hard, outer layer) and cancellous tissue (the spongy, inner layer that contains red marrow).

Detailed explanation-5: -Stem cells in the red bone marrow are called hemocytoblasts. They give rise to all of the formed elements in blood. If a stem cell commits to becoming a cell called a proerythroblast, it will develop into a new red blood cell. The formation of a red blood cell takes about 2 days.
