Question
Inhaled food or foreign objects are most likely to lodge in which part of the respiratory system? a. Pharynx b. Right bronchus c. Left bronchus d. Bronchioles What is the purpose of surfactant? a. Facilitate in the diffusion of oxygen across the respiratory membrane b. Transport oxygen to the alveoli c. Purify the air entering the respiratory tract d. Keep alveoli from collapsing What is one of the purposes of the fluid in the pleural cavity? a. Lubricate the pleural surfaces to allow them to glide painlessly during lung expansion and contraction b. Warm and moisten lung tissueExplanation / Answer
4) b. Inheld food or foreign objects are most likely to lodge in right bronchus of the respiratory system. The right bronchus is wider than the left and these differences affect the right lung to aspirational problems. If food, liquids, or foreign bodies are aspirated, they will tend to lodge in the right bronchus.
5) d.The purpose of surfactant is keep alveoli from collapsing.Surfactant reduces the surface tension of fluid in the lungs and helps make the small air sacs in the alveoli more stable. This keeps them from collapsing when an individual exhales.
6) The pleural cavity contains pleural fluid, which acts as a lubricant and allows the pleurae to slide effortlessly against each other during respiratory movements.
