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.
Answer:
The baby starts breathing
Explanation:
While in the womb, a fetus has its oxygen delivered to it, and the waste products removed (all via the mother's bloodstream), so there is no reason to separate all the chambers of the heart while still in the womb.
