PHYSIOLOGY IS THE BRANCH OF MEDICINE THAT FOCUSES ON THE STUDY OF THE FUNCTIONS AND MECHANISMS OF THE HUMAN BODY. IT EXPLAINS HOW THE BODY’S SYSTEMS—SUCH AS THE CARDIOVASCULAR, RESPIRATORY, NERVOUS, MUSCULOSKELETAL AND DIGESTIVE SYSTEMS WORK TO MAINTAIN HOMEOSTASIS AND SUPPORT LIFE. PHYSIOLOGY IS FUNDAMENTAL FOR UNDERSTANDING HOW THE BODY REACTS TO NORMAL ACTIVITIES AND HOW IT RESPONDS TO DISEASE OR INJURY.

Key Topics Covered: Physiology includes the study of cellular physiology, neurophysiology, endocrinology, cardiovascular physiology, respiratory physiology, renal physiology, and muscle function. Students learn about electrophysiological properties, nervous system signaling, hormonal regulation, blood circulation, and digestion/absorption mechanisms. It also covers exercise physiology, stress responses, and metabolism.

Importance: Physiology provides critical insights into how the human body operates under normal and stressed conditions. It enables future healthcare professionals to understand how diseases disrupt body functions, aiding in diagnosis, treatment planning, and prevention strategies. Physiology is a key area in understanding pharmacology and therapeutics, as it forms the basis for how drugs and interventions affect body systems.

Learning Methods: Physiology is taught through lectures, laboratory experiments, demonstrations, and clinical sessions. Students engage in practical exercises, such as measuring blood pressure, respiratory volumes, and electrical activity in muscles. Case studies and clinical correlations are integrated to show how physiological principles apply to real-world medical conditions.
