Question

1) Explain the chemical process involved in respiratory acid-base regulation (bicarbonate buffering system).  Include CO2, H+, and carbonic acid.

2) Define respiratory acidosis and alkalosis.

3) If you travel from Philadelphia (elevation ~40 feet) to the top of Pikes Peak in Colorado (elevation 14,114 feet), how will the drop in barometric pressure affect O2 and CO2 transport from the alveoli into the blood (external respiration)?

4) When you travel to Pikes Peak, ventilation (tidal volume and breathing frequency) may increase to compensate for a reduction in blood oxygen saturation.  What impact will this increase in ventilation have on acid-base regulation and what condition may arise (respiratory acidosis or alkalosis)?

5) Acute mountain sickness (AMS) may occur in some individuals after ascending to higher elevations without acclimatizing.  Symptoms begin in 6-10 hours and usually subside in 24-48 hours and may include nausea, vomiting, fatigue, and lightheadedness.  What is thought to be the cause of AMS?

Explanation / Answer

Tge lungs are one of the vital organs that maintains the acid base balance. This hapoens through the bicarbonate buffering system.
