WebHow are leaves adapted for gas exchange? Leaves have a large surface area, which means more space to allow CO2 to enter. They are thin so there is less for gases to travel. Leaves contain Stomata; these are small holes found distributed throughout the leaf which open and close, allowing gas exchange. Cells are organised in layers within the leaf. WebHow does air diffuse from the alveoli into our blood? 1. Blood arriving at the lungs has just returned from the body and contains a high concentration of CO2 and low concentration of O2. 2.

WebThe Respiratory System: The lungs are major organs of the respiratory system. Structures within the lungs play an important role in the process of gas exchange. Gas exchange allows oxygen to move from the respiratory system into the bloodstream and moves carbon dioxide from the blood into the lungs.

WebThe lungs contain lots of alveoli, and each one is microscopic. The alveoli are the sites of gas exchange. Oxygen in the air diffuses into the blood stream and carbon dioxide diffuses into the air. The alveoli are adapted to make the rate of gas exchange as fast as possible. The millions of alveoli mean that the lungs have a huge surface area.
