1. In a healthy person, the air reaching the alveoli with each breath contains about ml of fresh air diluted by about ml of stale air. O 200; 100 O s00: 200 500; 2000 O 2000;500 C) 5000; 200 s. All of the following statements about lung ventilation are correct except: Lung inflation requires sufficient force to overcome the elasticity of lung tissue and the surface tension in the alveoli. When stretched, certain cells within the alveoli release surfactant. Surfactant decreases the surface tension of a liquid. Surface tension results from the attractive forces of water molecules pulling from the sides and from below the surface of a liquid. ⑨ Premature babies suffer from respiratory distress syndrome because cells in their alveoli produce too much surfactant, which dogs the lungs. 6. ThePoz in lung capillaries allows hemoglobin to carry o2 molecules, but when the blood returns to the lungs, hemoglobin usually high; four; no low; four; no high; four; three low; two; no high; three; four
