Physiology

Physiology is the study of the physiology of vital organs and systems, including how organ systems, cells, and biomolecules perform chemical and physical processes in living organisms, and is considered a sub-discipline of biology.

According to the classes of organisms, the domain can be divided into:

• medical physiology
• animal physiology
• plant physiology
• Cell Physiology
• Comparative physiology

There are many ways to categorize the subdisciplines of physiology:

• based on the taxa studied: human physiology, animal physiology, plant physiology, microbial physiology, viral physiology
• based on the level of organization: cell physiology, molecular physiology, systems physiology, organismal physiology, ecological physiology, integrative physiology
• based on the process that causes physiological variation: developmental physiology, environmental physiology, evolutionary physiology
• based on the ultimate goals of the research: applied physiology, non-applied
