Final answer:
Water helps regulate body temperature and remove wastes by acting as a coolant and aiding in waste elimination.
Step-by-step explanation:
Water helps regulate body temperature and remove wastes by acting as a coolant and aiding in waste elimination. When the body is too warm, sweat glands release sweat which evaporates from the skin, removing thermal energy and cooling the body. Adequate fluid intake is essential to balance the loss of water during the sweat response. Additionally, water helps in waste elimination through the production of urine, which carries waste products out of the body.
