In the red bone marrow.
Only the red bone marrow of the - pelvis, - vertebrae, - ribs, skull, - sternum, - sacrum, and the - proximal ends of femurs produce new blood cells in adults.
New red blood cells are formed by the red bone marrow located in the spongy bone in a process called hemopoesis. I hope that helps :-)
Skin cells White blood cells Red blood cells New cell (formed from existing cells)
it travels through your bones by bone marrow, a jellylike substance, where new blood cells are constantly being produced
Because blood is produed in your bone marrow (middle of bone)
Red blood cells are formed in the red bone marrow of bones. Stem cells in the red bone marrow called hemocytoblasts give rise to all of the formed elements in blood. If a hemocytoblast commits to becoming a cell called a proerythroblast, it will develop into a new red blood cell.The formation of a red blood cell from hemocytoblast takes about 2 days. The body makes about two million red blood cells every second.

Blood is produced in the bone marrow - the innermost part of the bone.
marrow bone cells
Everything in your body is alive, including your bones. They are made of millions of cells that carry out activities such as cell division for repair and growth. The stuff in the middle is called bone marrow. It is the spot where new blood cells such as erythrocytes (red blood cells) and leukocytes (white blood cells) are made.
That's where new blood cells are made.
Bones are light because they are hollow inside and filled primarily with marrow, a spongy substance which produces new red blood cells in large bones.
