What is Physiology?

Physiology is the scientific study of the functions and processes of living organisms. It is a vast field that encompasses a wide range of topics, which includes the study of how cells, tissues, and organs function, how the body responds to various stimuli, and how the body systems work together to maintain balance.

Physiology encompasses many different subfields, including cellular physiology, which focuses on the functions of cells; neurophysiology, which studies the function of the nervous system; cardiovascular physiology, which studies the function of the heart and blood vessels; and respiratory physiology, which studies the function of the respiratory system.

Physiology is an important field of study that helps to understand how the body works and how it is affected by various no of factors, such as disease, injury, and environmental conditions. It is a vital part of many medical and scientific disciplines and is essential for the development of new treatments and therapies.

Physiology is the discipline of biology concerned with the function of organs and organ systems, as well as how they interact within the body to respond to stimuli. It examines life from the single cell, where it intersects with biochemistry and molecular biology, through issues about how individual organs work (e.g., heart, lungs, kidneys), to the whole-organism level, where physiologists investigate hormone implications on behaviour and brain function. As a result, physiology has something to say about everything: our integrated approach makes physiologists excellent contributors to fields ranging from genetics to psychology. Neuroscience is a section of physiology, and this vital subfield is addressed in the Physiology of Organisms course.
