The human body is composed of many types of cells. But none of
them perform their function well on their own because they were
designed to function as part of something much more
complex—you!
An adult has about a hundred trillion cells arranged in four
primary tissues that make up all the organs of the body. The four
tissues are epithelium, connective tissue, muscle, and nerve. An
understanding of these primary tissues greatly aids in
understanding the structure and function of the organs of the
body. Although our skin and kidneys look totally different to
the unaided eye, under the microscope they are seen to be made up
of a unique combination of the same four primary tissues.
A general understanding of gross anatomy is important to the
student of human biology, but most organs reveal little about how
they actually work when viewed in this way. As with most topics in
this series, Dr. Menton and his students again turn to the
microscope to better understand how the various organs and organ
systems work.
