Human Physiology is a course that explores the functions and mechanisms of the human body, focusing on how various systems work individually and together to maintain life. It covers the study of cells, tissues, organs, and organ systems, examining their roles in processes such as metabolism, respiration, circulation, digestion, excretion, and reproduction. The course emphasizes the regulation of body functions through homeostasis, hormonal control, and neural communication.

Students learn about the cardiovascular system, including heart function and blood circulation, as well as the respiratory system’s role in gas exchange. The nervous and endocrine systems are studied to understand how the body processes information and regulates physiological functions. The course also delves into muscle contraction, movement, and the skeletal system’s support functions. Additionally, the digestive system is explored in terms of nutrient absorption and energy metabolism, while the urinary system is examined for waste removal and fluid balance. 

A significant part of the course involves understanding the physiological responses to internal and external changes, such as exercise, stress, and disease. Practical applications often include laboratory experiments, case studies, and clinical correlations that link theoretical knowledge to real-world medical and health sciences. The study of human physiology is foundational for careers in medicine, nursing, physical therapy, and other health-related fields, providing essential knowledge about the body's functioning and adaptation to different conditions.
