One person is stabbed in the chest, and their lung collapses. (B) In that tissue, would hemoglobin's affinity for O2 increase or decrease? (A) List three factors that would potentially alter the affinity of hemoglobin for O2 in the ECF of metabolically active tissue. This fluid, in turn, pulls on the lungs, causing them to increase in volume. By contracting it, the volume of the thoracic cavity increases, thereby decreasing the pressure on the pleural fluid. Predict: (A) Will the patient's tidal volume be affected by the disease, and if so, in what manner? (B) Will the patient's physiological dead space change, and if so, in what manner? Assume you are healthy: When you inhale, the sheet of muscle responsible for most of this inspiration is called the diaphragm. SOLVED: What structures are NOT considered part of the anatomical dead space in the airways/lungs? Which part(s) are involved in the exchange between air and blood? Emphysema is characterized by the dilation of alveolar spaces, destruction of alveolar walls, increased compliance, and loss of elastance.
