D) decrease the rate of carbon dioxide diffusion from the blood to the alveoli.

Answer 1

1.A person has just received a kidney transplant and is taking cyclosporin A.What does this medication do?

Answer: suppresses helper T cells, thus preventing rejection

Cyclosporin is a Immunosuppressants.

Immunosuppressants inhibit T-lymphocyte synthesis, which preventing an immune response to an organ i.e. kidney transplant.

2.The partial pressure of oxygen in the interstitial space of peripheral tissues is approximately.

Answer: 40 mm Hg

The partial pressure of O2 in tissues is 40 mmHg is a low as compared to partial pressure of oxygen in the blood which is about 100 mm Hg.

3. Increasing the alveolar ventilation rate will

Answer:decrease the partial pressure of carbon dioxide in the alveoli

Alveolar ventilation rate is the exchange of gases between alveoli and the external surrounding.
