Blood pH varies between 735 and 745 with targeted value of 7

Blood pH varies between 7.35 and 7.45, with targeted value of 7.4. If someone\'s blood pH begins to decrease, chemoreceptors detect this change and send the information to the brain. The brain analyzes the input and sends out a command to the respiratory muscles, causing breathing rate to increase, which reduces carbon dioxide levels, and thereby increases the pH of her blood.

Name the body part, value(s), or actions in the specific scenario involving pH.
