Let us learn about Human Physiology and how we humans function
Physiology is the study of the parts of living organisms.
Introduction:
Physiology is the study of the functions of living organisms. It is divided into many branches. We are concerned with Human Physiology. In Physiology, understanding the mechanisms that regulate bodily functions is essential.
Physiology is derived from a Greek word with a Latin equivalent, Physiologia, meaning “natural knowledge”. Physiology is the branch of science that deals with the functions of the body and how these functions occur and are controlled. It also describes which organs initiate and maintain these functions.
A living organism comprises different organs. Body organs function so that mild variations in the external environment do not alter the body’s internal environment, which is kept constant within the normal range.
In Physiology, we study the functions of the living organism. The word Physiology was introduced by Jean Fernel (1497-1558), a French physician. Understanding the mechanisms that regulate bodily functions is essential in physiology.
Physiology is derived from a Greek word meaning “natural knowledge.” The ancient Greek phrase nature origin” and its study indicate an innate scientific understanding of a living body’s station, functions, and mechanisms.
Physiology is the branch of biological science that deals with the body’s functions. It also describes the organs that initiate and control these functions.
Divisions of Physiology:
It comprises many branches.
1. Human Physiology
2. Animal Physiology
3. Plant Physiology
4. Cell Physiology
We are concerned with Human Physiology.
A living organism is composed of many organs that respond to changes in its internal and external environments.
Body organs function so that mild variations in the external environment do not alter the body’s internal environment, which is kept constant within the normal range.
Physiological condition is the condition of normal function, while pathological condition refers to altered physiology-abnormal conditions.
Physiological function depends on
1. Biophysical processes
2. Biochemical processes
3. Homeostatic control
4. Rapid and precise communication between cells occurs in various ways, for example, through chemical and electrical methods.
Animal experiments have provided knowledge of human physiology. Anatomy and physiology are intrinsically related. Physiology is included in medical study globally, and many universities offer bachelor’s, master’s, and Ph.D. degrees in physiology.
Any change in physiology will impact an individual’s physical and mental functions. The study of physiology focuses on the level of organs and systems within the body, and the biological basis of thebody’s operations.
By studying human physiology, we understand how the body maintains normal health and responds to and adapts to challenges in both internal and external environments.
Physiology is a fascinating and dynamic subject that underpins translational and clinical medicine and the interface between the physical and life sciences.
Developments:
Documents reveal that the study of medical or human physiology began in Greece in the late 5th century BC, with Hippocrates. Around the same time, it also started in India and some other countries.
Later, many scientists, philosophers, and thinkers contributed to the development of physiology. Some of them are Galen, Aristotle, Claude Bernard, Walter B. Cannon, and many others.
Scopes in physiology
Anatomy and physiology are intrinsically related. Physiology is included in medical study globally, and many universities offer bachelor’s, master’s, and Ph.D. degrees in physiology.
Physiology is an essential subject in medical education for M.B.B.S. degrees. It is crucial in other systems, such as B.Sc. M.Sc. physiology.
A physiologist may be posted in medical colleges as a tutor, assistant professor, associate Professor, or Professor.
Exercise physiology is the study of physical activity. The word exercise comes from the Latin word drive forth’’
Exercise has been considered important to human health for thousands of years in ancient cultures. The Greek physician Hippocrates supported exercise and recommended moderate activity to maintain health and improve it.
Many careers in exercise physiology are available, and job opportunities are expected to increase as the population ages and obesity rates continue to rise. An exercise physiologist may pursue research work.
Physiologists can work in various clinical or non-clinical settings,
including fitness centers, community organizations, and corporate fitness.
Sports physiologists may work in private fitness clinics. They may start their own clinic.
Clinical physiologists may be employed by hospitals, community facilities, industries, and nursing homes.
