Ventilation refers to the process of bre

Question 11

Which of the following would you expect to happen to cellular respiration during exercise?

Accepted Answer

A) Increased cellular respiration occurs during exercise, causing a rise in plasma PCO2, which is detected by central chemoreceptors in the brain and perhaps peripheral chemoreceptors in the carotid sinus and aorta to cause an increase in respiration rate. 
B) Decreased cellular respiration occurs during exercise, causing a rise in plasma PCO2, which is detected by central chemoreceptors in the brain and perhaps peripheral chemoreceptors in the carotid sinus and aorta to cause a decrease in respiration rate. 
C) Exercise causes a decrease in cellular respiration by shifting peripheral chemoreceptors in the heart to cause retention of oxygen. 
D) Increased cellular respiration occurs during exercise, causing a decrease in plasma PCO2, which is detected by central chemoreceptors in the brain and perhaps peripheral chemoreceptors in the carotid sinus and aorta to cause a decrease in respiration rate.

Question 13

The pneumotaxic center operates mainly to prevent overinflation of lung tissue.

Accepted Answer

A) True 
 B)False

Question 14

The contraction of the abdominal muscles and the sternocleidomastoid allow much more air to leave the lungs than does the simple recoil of the lungs.

Accepted Answer
