Question

3. An increase in skeletal muscle activity results in localized increases in the partial pressure of carbon dioxide which in turn reduces the local blood pH. Which of the following effects best explains this statement? A. Bohr effect B. Haldane effect C. Charles effect D. Graham's effect 54. Mr. Philips suffered from a rare neurological disorder that affected the phrenic nerve. As a result, he was experiencing respiratory issues (shallow inspirations and expirations) despite having healthy lung tissue. Which of the following explains Mr. Phillips' most basic problem? A.

A. low pressure; high volume B. high pressure; low volume C. pulmonary arteries deliver venous blood to lungs for oxygenation pulmonary veins carry oxygenated blood from respiratory zones to the heart

Explanation / Answer

53.Bohr effect.

Increase in CO2 Levels result in decreased pH

54.Boyles law

phrenic nerve supplies the diaphragm.if the nerve gets damaged then paralysis of diaphragm will result in decrease in extent of respiration.

Less change in volume, less development of gradient in pressure ,less inspiration and expiration.

55.high pressure ,low volume
