the body. 2. Give three reasons why water is necessary for the body to function.

Water is essential for the body to function properly. Here are three reasons why water is necessary:<br /><br />1. Regulating body temperature: Water helps regulate body temperature through sweating and respiration. When the body overheats, sweat glands produce sweat, which evaporates and cools the skin. This process helps maintain a stable internal temperature.<br /><br />2. Lubricating joints: Water acts as a lubricant for the joints, reducing friction and allowing for smooth movement. It also helps cushion and protect the joints from impact and wear and tear.<br /><br />3. Removing waste: Water plays a crucial role in the body's waste removal system. It helps dissolve waste products and carry them through the bloodstream to the kidneys, where they are filtered out and excreted in the urine. Without adequate water intake, the body may struggle to remove waste efficiently, leading to potential health issues.
