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.

It should be noted that there is no consensus on the actual number of cells in the human body; estimates vary widely.

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..
