There are three main types of gas exchange that occur in animals:
1. Direct diffusion: In this type of gas exchange, gases such as oxygen and carbon dioxide diffuse directly across the respiratory surface (such as the skin or gills) into and out of the animal's body. This is common in small, simple organisms like flatworms and some aquatic invertebrates.
2. Tracheal system: Insects and some other arthropods have a tracheal system, which consists of a network of tubes that deliver oxygen directly to the cells of the body. Air enters the body through small openings called spiracles and travels through the tracheal tubes to reach the cells.
3. Respiratory system: Most vertebrates have a specialized respiratory system that includes organs such as lungs or gills. In these animals, oxygen is taken in through the respiratory surface (such as the lungs) and transported to the cells via the circulatory system. Carbon dioxide is then removed from the body in a similar manner.

1. Diffusion is the passive movement of gas molecules from an area of high concentration to an area of low concentration. In animals, diffusion occurs across the surface of the body, such as the skin or the lining of the lungs.
2. Bulk flow is the movement of gas molecules in a mass of fluid. In animals, bulk flow occurs in the blood, which transports oxygen and carbon dioxide throughout the body.
3. Facilitation is the movement of gas molecules across a membrane with the help of a protein channel. In animals, facilitation occurs in the lungs, where oxygen and carbon dioxide are transported across the alveolar-capillary membrane.
4. Active transport is the movement of gas molecules across a membrane against a concentration gradient. In animals, active transport occurs in the kidneys, where hydrogen ions are transported out of the blood and into the urine.
