Human physiology studies the functions and mechanisms of the human body, including digestion, respiration, circulation, excretion, nervous and endocrine regulation, reproduction, and immunity. It explains how organs and systems work individually and together to maintain homeostasis, support growth, respond to stimuli, and ensure survival and overall health.
Breathing and gas exchange involve inhalation and exhalation, allowing oxygen intake for respiration and carbon dioxide removal from the body.
Body fluids and their elimination involve balancing water, salts, and metabolic wastes, removing them through urine, sweat, and excretory processes.
Excretory products and their elimination remove metabolic wastes like urea, carbon dioxide, and excess salts from the body.
Locomotion and movement involve muscles and skeleton working together, enabling animals to move, maintain posture, and interact with their environment.
Neural control and coordination involve the nervous system detecting stimuli, transmitting signals, and regulating body responses for proper functioning.
Chemical coordination and integration use hormones to regulate body functions, growth, reproduction, and maintain physiological balance.
