PPT-2.46 Explain how alveoli are adapted for gas

exchange by diffusion between air in the lungs and blood in capillaries What can you tell me about alveoli Alveoli The tiny air sacs at the end of each bronchiole are specially designed for gas exchange . How adapted to live at sea. They are excellent divers and swimmers.. They use their wings to swim.. Their feathers are waterproof and act like a raincoat.. They can raft on the ocean. . They have a white chest to make it harder for their prey to see them.. We are learning to: appreciate how some organisms live in very unusual conditions.. What I’m looking for:. - You recognise what an . extremophile . is. - You learn about . three. case studies and can explain how they are adapted to their environment.. mammalian lungs made of?. Success Criteria . Describe, with the aid of diagrams and photographs, the distribution of cartilage, ciliated epithelium, goblet cells, smooth muscle and elastic fibres in the trachea, bronchi, bronchioles and alveoli of the mammalian gaseous exchange system; .

The respiratory system . starts. with a pair of . external nostrils . The . nostrils open into . nasal passage . that is situated above the . buccal cavity. “Air Sacs”. Resemble bunches of grapes. Make up bulk of lungs. Respiratory Zone. Includes respiratory bronchioles, alveolar ducts, alveolar sacs, and alveoli. Only places where gas exchange occurs. The Conducting Zone. Nose. Only external visible part of the respiratory system. Air enters the nose by passing through the nostrils. The interior of the nose consists of the nasal cavity which is divided by the nasal septum.
