Animal Breathing Mechanisms

The video tutorial explains how different animals breathe. Humans and mammals use lungs for breathing, where oxygen is exchanged with carbon dioxide in the blood. Aquatic animals like fish use gills to extract oxygen from water. Amphibians such as frogs use lungs on land and skin in water. Insects breathe through spiracles connected to air tubes. Some animals, like earthworms, breathe through their moist skin. The video highlights the diversity of respiratory systems across animal species.
