Question

1. the pharynx is an enlargement at the top of the trachea that houses the vocal cords. true false 19) an ad suggests their vitamin supplement gives the body energy, but it may be misleading since cells primarily use what for energy? a) minerals b) proteins c) amino acids d) carbohydrates 20) name the volume of air that is moved in (or out) during a single quiet respiratory cycle. a) vital capacity b) tidal volume c) expiratory reserve volume d) inspiratory reserve volume 21) which of the following respiratory volumes is the largest? a) inspiratory reserve volume b) residual volume c) expiratory reserve volume d) tidal volume 22) which of the following is not a function of the mucus-lined nasal passages at or below normal body temperature? a) moistening inspired air b) cooling exhaled air c) trapping small particles d) warming inspired air 23) describe the process of ventilation. a) delivery of carbon dioxide to cells b) delivery of oxygen to cells c) forcible movement of oxygen molecules into the bloodstream d) movement of air into and out of lungs 24) what respiratory volumes, when added together, equal the vital capacity (vc)? a) vc = tv + irv b) vc = ic + frc c) vc = erv + rv d) vc = tv + irv + erv 25) adh signaling leads to the formation of water channels in cell membranes within the kidneys. what forms the water channels? a) cytopores b) pyrogens c) aquaporins d) podocytes 26) another word for breathing is ventilation. true false 27) aldosterone from the adrenal cortex causes sodium ions to be______ and potassium ions to be______. a) excreted; excreted b) excreted; conserved c) conserved; excreted d) conserved; conserved

Explanation:

1. The larynx, not the pharynx, houses the vocal cords.
2. Carbohydrates are the body's primary energy source.
3. Tidal volume is the air moved in/out during a quiet respiratory cycle.
4. Inspiratory reserve volume is the largest respiratory volume.
5. Cooling exhaled air is not a function of the nasal passages.
6. Ventilation is the movement of air into and out of lungs.
7. Vital capacity \( VC = TV+IRV + ERV \).
8. Aquaporins form water channels in kidney cell membranes.
9. Ventilation is another word for breathing.
10. Aldosterone causes sodium ions to be conserved and potassium ions to be excreted.

5. B. Cooling exhaled air
6. D. Movement of air into and out of lungs
7. D. \( VC = TV+IRV + ERV \)
8. C. Aquaporins
9. True
