where do you find red and yellow marrow
Bone marrow The composition of marrow is dynamic, as the mixture of cellular and non-cellular components (connective tissue) shifts with age and in response to systemic factors. In humans, marrow is colloquially characterized as "red" or "yellow" marrow (Latin: medulla ossium rubra, Latin: medulla ossium flava, respectively) depending on the prevalence of hematopoetic cells vs fat cells. While the precise mechanisms underlying marrow regulation are not understood,[6] compositional changes occur according to stereotypical patterns.[9] For example, a newborn baby's bones exclusively contain hematopoietically active "red" marrow, and there is a progressive conversion towards "yellow" marrow with age. In adults, red marrow is found mainly in the central skeleton, such as the pelvis, sternum, cranium, ribs, vertebrae and scapulae, and variably found in the proximal epiphyseal ends of long bones such as the femur and humerus. In circumstances of chronic hypoxia, the body can convert yellow marrow back to red marrow to increase blood cell production.[10]
