Question

The most important chemical regulator of respiration is question 2 options: carbon dioxide. sodium ions. potassium ions. oxygen. nitrogen.

Answer 1

The most important chemical regulator of respiration is carbon dioxide.
Breath control is accomplished chemically, mainly using Carbon dioxide and oxygen chemoreceptors. The most important chemical regulator of respiration is either carbon dioxide or oxygen, since the chemical regulation of breathing is different in healthy and sick individuals.

Answer 2

CARBON DIOXIDE is the most important chemical regulator of respiration. Respiration primarily is the process of gas (carbon dioxide and oxygen) exchange between the air and the person's blood. There is a signal to increase ventilation when: there is to much carbon dioxide in the blood and if there is a decrease in the pH levels of the blood.

Another important chemical regulator is oxygen. There is a signal to increase ventilation when there is a drop of oxygen levels in the body.
