Document Summary

Histamines contract smooth muscle to reduce diameter of airway even more. Cingulair, the drug, would actually stop this mucus production in order to allow more air to flow into our alveolar ducts and into lungs. Lumen of alveolus: within respiratory membrane are capillaries. The little dots represent the nuclei of simple squamous cells. Simple squamous makes up the wall of the alveolus. Oxygen will attach to the fe on the hemoglobin on the erythrocytes. Each simple squamous cell is called an alveolar type i cell: makes up wall (gaseous exchange cell), these are the cells that are scattered throughout the walls of the alveoli. Alveolar type ii cells (like simple cuboidal cells) When you exhale forcibly, opposite sides of the alveolus collapse! Without surfactant, we can"t open these alveoli. Surfactant: helps keep alveolar wall moist, so opposing walls/membranes won"t stick together. Live in lumen of alveoli and in walls of alveoli to intercept any foreign material that get that far!
