The organ that is adapted for gaseous
WebbLarge surface area: Lungs provide a large surface area in the form of alveoli inside for the exchange of gases by diffusion. This helps in the absorption of oxygen. b. Thin walls: The air sacs/alveoli are thin which allows the quick diffusion of the gases through it. WebbDescribe how gaseous exchange takes place in terrestrial plants. 8. State two ways in which floating leaves of aquatic plants are adapted to gaseous exchange. 9. State four ways in which respiratory surfaces are suited to their function. 10.

To elimate the carbon dioxide in the lungs the floor of the mouth moves down, drawing the air out of the lungs and into the mouth. Finally the nostrils are opened and the floor of the mouth moved up pushing the air out of the nostrils.
WebbRespiration ensures that cells, tissues, and major organs of the body receive an adequate supply of oxygen and that the carbon dioxide, a waste product, is efficiently removed; the exchange of oxygen and carbon dioxide occurs via diffusion across cell membranes.
