Question

The upper trace in the graph to the right shows total blood CO_2 concentration as a function of CO_2 partial pressure for fully oxygenated blood. If the blood were suddenly deoxygenated, how would the curve change? shift up shift down no change Oxygen and carbon dioxide are exchanged in the lungs by active transport mechanism diffusion osmosis both a) and b) What is the best definition of "anatomical dead space?" The portion of the cranial vault not occupied by the brain Dart of your body that is not comDosed of living cells Mouth, trachea Mouth. Trachea, bronchi, bronchioles Mouth, trachea, bronchi, bronchioles, alveoli In the gill countercurrent gas exchange system (illustrated here), extracted from water mostly by the blood gills mostly by the blood the equally by the blood throughout the gills by active transport across the gill lamellae by the gradient between colloidal osmotic hydrostatic pressures As body mass increases. which of the following is true: mass-specific metabolic rate increases, and gas-exchange surface area increase mass-specific metabolic rate increases, and gas-exchange surface area decrease mass-specific metabolic rate decreases, and gas-exchange surface area increase mass-specific metabolic rate decreases, and gas-exchange surface area decrease mass-specific metabolic rate increases, and gas-exchange surface area

Explanation / Answer

42 : diffusion is the correct answer

43 D suits best as it comprises the region of anatomical dead space
