Yellow bone marrow contains a large percentage of fat cells.
No. It is composed of fatty tissue and it one place where extra stores of food are kept.
The percentage goes up. (Hematocrit is the percentage of red blood cells in a sample of whole blood, so if an elevated number of red blood cells is produced by your bone marrow, your hematocrit level should rise).
YesYes, from inside. But from outside it is composed of compact bone. Clavicle being an exception in that is has no cancellous bone.
In bone, there are osteoblasts (cells which build bone) and osteoclasts (cells which break down bone). In the bone marrow and spongy bone, there are hematopoietic cells (cells which make blood). Bone is a type of connective tissue that is made of specialized cells that all work together for a common function. Their cellular and extracellular matrix is what makes bone cells so unique.

Cellular metabolism takes place in bone cells in the same way that it takes place in any other cells. The outer layer of the bone, composed of calcium phosphate, is a secretion, not composed of living cells, but living cells are in the interior section or marrow of the bone.
Cells account for only 2% of the weight of a typical bone cell.
fat cells that create red blood cells
Yellow bone marrow contains a large percentage of fat cells.
No. It is composed of fatty tissue and it one place where extra stores of food are kept.
red cells, white cells, platelets, and plasma
The percentage goes up. (Hematocrit is the percentage of red blood cells in a sample of whole blood, so if an elevated number of red blood cells is produced by your bone marrow, your hematocrit level should rise).
