Detailed explanation-1: -The lungs and respiratory system allow us to breathe. They bring oxygen into our bodies (called inspiration, or inhalation) and send carbon dioxide out (called expiration, or exhalation). This exchange of oxygen and carbon dioxide is called respiration.
Detailed explanation-2: -The pH receptors in the brain are not involved in the regulation of the process of breathing in humans. The breathing in humans is mainly controlled by the diaphragm, intercostal muscles, and the nervous system.
Detailed explanation-3: -Evaporation is the transfer of heat by the evaporation of water. Because it takes a great deal of energy for a water molecule to change from a liquid to a gas, evaporating water (in the form of sweat) takes with it a great deal of energy from the skin.
