It enables information gained by molecular biology, genetics, pharmacology, biophysics, and biochemistry to be described in an integrated manner which can then be applied for improving quality of life. Physiology forms the bridge between all of the other biomedical sciences. It describes the chemistry and physics behind body functions, from signal transduction in cells to how organ system works together. Physiology is the study of how the human body functions. Physiology (Greek physis = “nature/origin and logia = “study of”)įather of modern experimental physiology: Claude Bernard Macroscopic anatomy deals with structures that can be viewed by the naked eye, while microscopic anatomy involves the cellular level study of internal organs and structures. It has many sub-disciplines, the major being gross or macroscopic anatomy and microscopic anatomy.

Anatomy (Greek anatomē = ‘dissection’)Īnatomy focuses on the study of physical structures and organs of living beings. This includes the branches that focus on specific biological processes, such as organismal interaction either between different organisms or, within the same organism. Let’s take a look at some of the important branches of biology.
