In the lungs, the respiratory membrane separates tiny sacs of air (pressure 1.00x105Pa) from the blood in the capillaries. These sacs are called alveoli. The average radius of the alveoli is 0.012 cm, and the air inside contains 20% oxygen. Assuming that the air behaves as an ideal gas at 300K, find the number of oxygen molecules in one of these sacs. Boltzmann constant =1.38 ×10−23 J K

1. Alveoli are air sacs in the lungs where gas exchange occurs with the blood. The tissue that makes up alveoli is simple squamous epithelium, which is different than the respiratory tract which is mostly pseudostratified columnar ciliated epithelium. Explain why there is a difference in tissue types. 2. Do you think the skin is a tissue or an organ? Explain why. 3. If you had to choose one type of epithelial tissue that is more important than the others,...
