Exhale means to breathe out, and its antonym is to breathe in, which is called inhale. Inhale means the act of breathing in or taking in air, gases, or other substances into the lungs or respiratory system. When exhaling, the lungs push air out through the nose or mouth, while when inhaling, air is drawn in through the nostrils or mouth. Inhaling is a vital process as it provides the body with oxygen, which is necessary for proper functioning. Conversely, exhaling removes carbon dioxide from the body, which is essential for maintaining a healthy pH balance in the blood.
