During post embryonic growth, and also in the adult, all the body cells are not capable of undergoing division. This is because they have become differentiated. But at some locations, undifferentiated cells are present which divide mitotically and replace the worn out ..

The human circulatory system is a closed circulatory system. The blood flows in closed vessels without coming in direct contact with the cells of the body..
