Explanation

Bone marrow is the flexible tissue found in the interior of bones. In humans, marrow in large bones produces new blood cells. It constitutes 4% of the total body mass of humans, i.e. , approximately 2.6 kg (5.7 lbs.) in adults weighing 65 kg or 143 lbs. Bone marrow also prevents the backflow of lymph, working as a vital part of the lymphatic system.
