Question

The path of air during inhalation takes which path? A) trachea, bronchioles, alveoli, bronchi B) trachea, bronchioles, bronchi, alveoli C) trachea, bronchi, bronchioles, alveoli The partial pressure of CO_2 in the atmosphere at sea level is 0.29 mm Hg. If an individual has a partial pressure of CO_2 in their arteries of 40mm Hg, the likely homeostatic response would be: A) to decrease metabolic rate, and thereby reduce CO_2 production. B) to decrease rate of ventilation. C) to acidify the blood so that less CO_2 can be carried. D) to increase the rate of breathing. E) Three of the above are correct responses. In a mammalian heart/circulation we would expect to find. A) oxygenated blood in the right atrium B) oxygenated blood leaving via the pulmonary artery C) oxygenated blood in the right ventricle D) deoxygenated blood in the right ventricle E) deoxygenated blood returning via the aorta In comparisons, external fertilization often yields more offspring than does internal fertilization. However, internal fertilization offers the advantage that A) it is the only way to ensure the survival of the species. B) it requires less time and energy to be devoted to reproduction C) the smaller number of offspring produced often receive a greater amount of parental investment and therefore survive better. D) it permits the most rapid population increase. E) it requires expression of fewer genes and maximizes genetic stability. Which statement about human male production or semen or ejaculate is false? A) The bulbourethral glands make the vast majority of the volume of the ejaculate. B) Sperm are produced in seminiferous vesicles. C) The seminal vesicles make a high pH solution which also contains fructose. D) The epididymis stores sperm. E) The prostate secretes milky solution into the urethra.

Explanation / Answer

8. The path of air during inhalation takes which path?

C) Trachea, bronchi, bronchioles, alveoli.

The air from the atmosphere is inhaled by the nostrils which is passed to the nasopharynx pathway. The air then reaches the oral pharynx and passes to the trachea through the glotis. The trachea is divided into right and left bronchi which is branched into bronchioles. At the end of each bronchioles alveoli is present.
