If a patient has a collapsed lung what changes to blood pH are likely to occur? Explain why this might happen.

How could the body compensate for these changes?

Expert Solution

A collapse of the lung occurs when the air that normally circulates within the lung leaks into the space between lung and chest wall. A buildup of air increases the pressure on lung, causing it to collapse. The blood pH is likely to decrease, when a patient has a collapsed lung. The patient has more CO₂ in blood.

CO₂ + H₂O ----->H₂CO₃

H₂CO₃ ----> H⁺ + to HCO₃^-

When blood pH is low and the blood becomes acidic. Normal blood pH of our body is set at 7.4.The presence of too many H⁺ ions make it acidic.

Bicarbonate Buffer System can help to compensate for these changes. They soak up extra H⁺ ions

PH = PKa + log [HCO₃^- ]/ [H₂CO₃]

HCO₃^- is a base and soaks up hydrogen ions.

If pH is too high, carbonic acid will donate H⁺ and pH will drop.

If pH is too low, bicarbonate will bond with H⁺ and pH will rise.

You are studying how changes in blood pH might be controlled by homeostasis. In a trial, you let a mouse run on a treadmill for a fixed period of time, and then you measure its blood pH. Intriguingly, you observe the blood pH drops (more acidic) as carbon dioxide is released into the bloodstream. Which component of the homeostatic feedback system is responsible for producing the correct response if the blood pH is far enough from normal that a response...
