The organ that is adapted for gaseous
WebbTheir cells are kept moist and gases diffuse quickly via direct diffusion. Flatworms are small, literally flat worms, which ‘breathe’ through diffusion across the outer membrane ( Figure 11.11). The flat shape of these organisms increases the surface area for diffusion, ensuring that each cell within the body is close to the outer membrane surface and has … WebbThe spiracles are openings of small tubes running into the insect's body, the larger ones being called tracheae and the smaller ones being called tracheoles. The ends of these tubes, which are in contact with individual cells, contain a small amount of fluid in which the gases are dissolved.

Webbinto the lungs by contraction of the floor of the mouth. 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. http://www.renataiguchi.com.br/tresaderm-for/how-are-fish-gills-adapted-for-gas-exchange
WebbThe human respiratory system is adapted to allow air to pass in and out of the body and also for efficient gas exchange to occur. The respiratory system includes air passages, pulmonary vessels, the lungs, and breathing muscles. Most of the organs of the respiratory system help to distribute air, but only the tiny alveoli and the alveolar ducts ...
