Has the total number of cells in your body changed since your birth Explain?

Yes it has. In order to grow in height and weight your body needs to increase the amount of cells. Your bones need to increase in width and length in order to do this you require both more osteocytes and osteoblasts. Muscles on the other hand do not increase in cell number rather as they get larger there are surrounding satellite cells that merge with the preexisting cells. Blood vessels must increases in length which requires more endothelium cells as well as smooth muscle cells. Likewise the digestive tract and urinary tract increases in size which requires an increase in numbers of cells. Organ systems also increase in size and require more cells to do so. Hope that helps
