Fish physiology refers to the study of the internal functions and structures of fish, including their respiratory, circulatory, digestive, and reproductive systems.
Think of a fish's physiology as its own personal "engine room." Just like an engine powers a car, a fish's physiology powers its ability to swim, breathe, eat, and reproduce.
Osmoregulation: The process by which fish regulate the balance of water and salts in their bodies.
Swim bladder: An internal gas-filled organ that helps fish control their buoyancy in water.
Gills: Respiratory organs in fish that extract oxygen from water.
