And the process by which we produce these blood cells is known as hematopoasis. So hematopoasis takes place in the red bone marrow of our spongy bone inside the epithesis of our bone. Now let's move on to our metaphosis. Inside the metaphysis, we have a special region known as our Epiphysical plate. Now, the Epiphysical plate is basically the region where in children as well as young adults, that's where our bone grows and elongates and basically increases in length. So this plate is found in our metaphysis section of our long bone.
