Anatomy and physiology is an area of study and is a division of biology. Anatomy is the study of the structure of organisms and physiology is the study of the function of those structures and how they interact in health and disease.
Several branches of anatomy exist. There is what is called gross anatomy which is the visual examination of structures with the unaided eye. For example, studying the skeleton to learn the location and names of the bones. There is pathological anatomy which is the study of the structures as they are affected by disease and illness.
Another branch is zoology, which is the study of anatomical structures in animals other than humans.
Human Anatomy and Physiology
I took an Anatomy and Physiology class in college. In lecture, we studied the systems of the body and how they operate together. We also studied malfunctions of body systems and their causes. In lab, we actually had cadavers to illustrate the organs of the body systems and to illustrate malfunctions. For example, I saw plaque in a heart artery of one of the cadavers.
Generally, anatomy is divided into microscopic and gross. Microscopic anatomy is a study of morphology of the human body that can be seen by microscope. Gross anatomy is the study of morphology of the human body with the naked eye. Anatomy can also be learned regionally as well as systematically. Physiology is the study of the functioning of living systems. It is how the organ systems, organs, and cells carry out the chemical or physical function that is in the living system.
