In order to have a complete understanding of physiological processes, it is often necessary to know gross anatomy as well as microscopic anatomy (i.e., histology). Often, it is important to know the number of a given structure under consideration. For example, a student of physiology should know the number of kidneys, nephrons, adrenal glands, cranial nerves, lungs, alveoli, etc. in the human body.
