The visceral pleura lines the outside of the lungs, the parietal pleura lines the thoracic cavity, and the intrapleural space seals the two layers together
The parietal pleura lines the outside of the lungs, the visceral pleura lines the thoracic cavity, and the intrapleural space seals the two layers together
The thoracic cavity and lungs are only connected by the visceral pleura
The thoracic cavity and lungs are only connected by the parietal pleura
What is the role of the alveolar macrophages and what happens if
they do not function properly?
They are type of phagocyte. If not functioning properly, the patient is at
increased risk for pulmonary infection.
They are type of eosinophil. If not functioning properly, the patient is at
increased risk for an allergic reaction..
They are type of monocyte. If not functioning properly, the patient is at
increased risk for tissue necrosis.
They are type of monocyte. If not functioning properly, the patient is at
increased risk for pulmonary infection.

- What are some factors that make the respiratory system prone (more likely) to infections? What natural safeguards are there to prevent lower respiratory tract infections?arrow_forwardDon Paladio had been a pharmacist in New York City. He retired to Florida and spent the better part of everyday swimming in the Gulf. He was healthy and strong. Gradually, however, his years of smoking began to compromise his lung's capacity. Soon, he could not swim at all. He enjoyed the beach from under his umbrella. Eventually, the trips to the beach were not possible. The diagnosis was pulmonary emphysema and COPD. Oxygen was needed, and his activities were diminished to cooking dinner for his wife and himself. Don was embarrassed about the oxygen tank and would no longer go out in public. He died when he was 85. 1.Discuss the impact of both diseases in Don's life 2.What, if anything, could have been done to make his suffering less difficult? 3.Identify characteristics of such long-term chronic illnesses that are particularly difficult. ***INCLUDE CITATIONS IN MLA 9TH EDITION PERDUE OWL***arrow_forwardWhy does the respiratory system need tonsils and macrophages?arrow_forward
