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.. How do oxygen and carbon dioxide move into and out of the lungs and blood?. Starter: . Sulking!

Transpulmonary. pressure. is the . difference in pressure between alveolar pressure and pleural pressure.. and Disorders. Gas Exchange. Gas exchange occurs in the alveoli due to the difference in the partial pressures of oxygen and carbon dioxide in the capillary blood and the alveoli.. Since the concentration of oxygen is greater in the alveoli, it diffuses into the capillary blood.. Presented by Toni Davis and Niamh McDonald. Function of the Respiratory System. What Does The Respiratory System Do?. The respiratory system takes in oxygen to circulate around the body for many uses such as creating ATP, supplying systems with oxygen for smelling and speaking.. - CATION, TEACHING MINOR (DAPE) ______________________________________ Developmental Adapted Physical Education, College of Allied Health & Nursing Department of Human Performance 1400 Highland Cente Do Now activity:.
