Human biology is an academic field of biology which focuses on humans; it is closely related to medicine, primate biology, and a number of other fields. A human being is a multicellular eukaryote consisting of an estimated 100 trillion cells. As a species, humans are primates and can be distinguished from other primates by their more highly evolved brains. Even though humans are multicellular animals, many of the basic life processes of human cells are basically the same as in simple unicellular eukaryotes such as yeast and even prokaryotes.
