Distinction between Physiology and Physiological Processes

What is the difference between physiology and physiological processes?

Physiology and physiological processes are closely related but distinct concepts in the field of science.

Physiology refers to the study of how living organisms function and how their various systems and structures work together to maintain life. It is a branch of biology that focuses on the physical and chemical processes that occur within living beings. Physiology encompasses the study of all the functions and activities carried out by living organisms, from the molecular level to the organism level

On the other hand, physiological processes specifically refer to the specific activities and functions that occur within an organism at the cellular, tissue, and organ level. These processes are the building blocks that contribute to the overall functioning of an organism. Physiological processes include activities such as respiration, digestion, circulation, metabolism, excretion, growth, and reproduction

In simpler terms, physiology is the broader field that encompasses the study of all living organisms and their functions, whereas physiological processes narrow down to the specific activities and functions that occur within an organism

To illustrate the difference, let’s consider the example of digestion. Physiology would involve studying the different organs and systems involved in the process of digestion, such as the mouth, stomach, intestines, and associated muscles, nerves, and blood vessels. It would also explore the chemical and molecular processes that occur during digestion, such as the breakdown of food and absorption of nutrients

On the other hand, physiological processes would specifically focus on the step-by-step activities that occur during digestion, such as the mechanical breakdown of food in the mouth, the secretion of digestive enzymes in the stomach, the absorption of nutrients in the intestines, and the elimination of waste materials through the excretory system

In summary, physiology is the overarching study of how living organisms function, while physiological processes concentrate on the specific activities and functions that occur within an organism
