WebRespiration refers to a process in which the energy is released from the glucose so that the life processes can continue. There are two types of respiration: Aerobic respiration: It needs oxygen. Anaerobic respiration: It does not need oxygen. Our respiratory system is adapted to carry the exchange of gases efficiently. WebThe human respiratory system. is adapted to allow air to pass in and out of the body, and for efficient gas exchange to happen. The lungs are enclosed in the thorax, surrounded … WebAlveoli are highly adapted for gas exchange by diffusion between air in the lungs, and blood in the capillaries. They are folded in order to maximise the surface area to volume ratio. This allows more gas exchange to take place.
