QUESTION 23 Imagine a disease that causes the bronchioles to constrict and limit air flow. What affect would this have on the body? A. hemoglobin O2 saturation would increase in the alveolar capillaries B. hemoglobin O2 saturation would decrease in the avleolar capillaries C. oxygen delivery to peripheral tissues would improve D. respiration efficiency would increase E. carbon dioxide concentration would drop in the blood plasma QUESTION 24 Which of the following best represents the path of air from the environment into human lung tissue? I. nasal passage II. trachea (windpipe) III. alveoli IV. bronchi V. bronchioles A. I II IV. V. III B. I IV. III. II. V C. I II III. IV. V D. V III IV I E. II. III. IV. V I

The sequence of structures in the respiratory system that a molecule of inspired oxygen would travel through from its point of entry into the body to the point at which it reaches the bloodstream into which it will be absorbed is correctly detailed by which of the pathways listed below? A) nasal passages → glottis → larynx → pharynx → trachea → bronchi → bronchioles → alveoli B) nasal passages → larynx → glottis → pharynx → trachea → bronchioles → bronchi → alveoli C) nasal passages → glottis → pharynx → larynx → trachea → bronchi → bronchioles → alveoli D) nasal passages → pharynx → glottis → larynx → trachea → bronchi → bronchioles → alveoli

Hemoglobin (Hb) transports oxygen in the blood: $$\mathrm{HbH}^{+}(a q)+\mathrm{O}_{2}(a q)+\mathrm{H}_{2} \mathrm{O}(l) \longrightarrow \mathrm{HbO}_{2}(a q)+\mathrm{H}_{3} \mathrm{O}^{+}(a q)$$ In blood, $\left[\mathrm{H}_{3} \mathrm{O}^{+}\right]$ is held nearly constant at $4 \times 10^{-8} M.$ (a) How does the equilibrium position change in the lungs? (b) How does it change in $\mathrm{O}_{2}$ -deficient cells? (c) Excessive vomiting may lead to metabolic alkalosis, in which $\left[\mathrm{H}_{3} \mathrm{O}^{+}\right]$ in blood decreases. How does this condition affect the ability of $\mathrm{Hb}$ to transport $\mathrm{O}_{2} ?$ (d) Diabetes mellitus may lead to metabolic acidosis, in which $\left[\mathrm{H}_{3} \mathrm{O}^{+}\right]$ in blood increases. How does this condition affect the ability of $\mathrm{Hb}$ to transport $\mathrm{O}_{2} ?$
