Gaseous exchange surfaces inside the body of terrestrial animals help to protect the delicate respiratory membranes from drying out and damage. This internal arrangement also helps to regulate gas exchange and maintain proper moisture levels, especially in dry environments. Additionally, it provides a more controlled and efficient system for exchanging gases such as oxygen and carbon dioxide with the bloodstream.

Gaseous exchange is a natural process, ventilation is a forced process.
In lower plants such as mosses and liverworts, gaseous exchange occurs through simple diffusion across the cell membranes. These plants lack specialized structures like stomata found in higher plants, so gases enter and exit the plant cells directly through their surfaces. This process is limited by the surface area available for exchange, making lower plants reliant on moist environments for efficient gaseous exchange.
Plants and animals affect their environment directly. This is what forms the biodiversity as plants will provide food for the animals and they both need each other for the gaseous exchange.
The site for gaseous exchange is the lungs. Carbon dioxide is exhaled and is substituted for oxygen which is inhaled.

alveoli is the site for gaseous exchange. They are the air filled sacs where carbon dioxide and oxygen is exchanged
