Water is the most abundant chemical substance in the body, making up about 60% to 80% of body weight. It is essential for various physiological processes such as transportation of nutrients and waste products, maintaining body temperature, and lubricating joints. Oxygen is also important for respiration, but it is not as abundant in the body as water.
