Health sciences encompass a broad spectrum of disciplines aimed at understanding and promoting human health. This interdisciplinary field integrates knowledge from biology, physiology, environmental health, and health informatics to address various aspects of healthcare, disease prevention, and public health.

Biology serves as the foundation, providing insights into the structure, function, and processes of living organisms, including humans. Physiology delves deeper into how the body works, focusing on the functions of organs and systems, and how they respond to stimuli and maintain homeostasis. Environmental health examines the impact of environmental factors on human health, ranging from air and water quality to workplace safety and community sanitation. Health informatics utilizes technology and data analysis to improve healthcare delivery, patient outcomes, and health management systems.
