Question

What stimulates increased respiration at the beginning of exercise?

Answer 1

Answer:

d. sensory input from receptors in joints, neural input from the motor cortex, and other factors is the correct answer

Explanation:

• sensory input from receptors in joints, neural input from the motor cortex, and other factors stimulates increased respiration at the beginning of exercise.  

• As we do exercise our muscles gets active, it produces lactic acid that enters the blood and hydrogen ions are a release that reduces the pH due to a decrease in the pH stimulates the sensory receptors to carry nerve impulses to respiratory muscles and this increase respiration at the beginning of the exercise.

• In medual the respiratory center is stimulated by increasing the carbon dioxide concentration.
