Physiology is the study of the functions of living organisms and how their body systems work. It focuses on studying the processes in humans, plants, animals, and cells. Understanding these processes is vital for a career as a Physiologist.
Physiologists use scientific knowledge to study how the body functions in normal and abnormal conditions. Their work contributes to clinical, academic, research and public health sectors.
This guide will explore the different careers of a physiologist, various types, the necessary skills, career opportunities, salary expectations and the roadmap on how to become a physiologist in India.
Who is a Physiologist?
A physiologist is a scientist who studies the functions of living organisms and their body systems. They study the normal function of organs, tissues, cells and biological systems and how they are affected by ageing, disease, physical activity or environmental factors.
Unlike doctors or physicians, physiologists do not diagnose or treat patients. They are also different from physiotherapists, who help recover movement and physical function in patients.
The primary focus of a Physiologist is to perform research, lab experiments, clinical evaluation or specialized diagnostic procedures to learn how the body works. Their research adds to the progress of medicine, rehabilitation, sports performance, pharmaceuticals and preventive health care.
What Does a Physiologist do?
A day in the life of a physiologist varies depending on their area of specialization and workplace. They may conduct experiments, analyze data, collaborate with healthcare teams or perform other functions. Below are some common duties of a Physiologist:
- Study how humans, animals, plants or cells work.
- Design and perform laboratory or field investigations.
- Collect, analyze and interpret scientific data.
- Work with doctors, researchers and health care teams on research projects.
- Support clinical studies, evaluate new treatments and medical technologies.
- Apply digital and AI-based methods for analysis of physiological data.
- Evaluate physical performance in sports, exercise, or rehabilitation settings.
- Write reports and publish research findings.
- Educate or supervise students at universities and laboratories.
