What are the primary sources that supply the body's need for water?

The primary sources that supply the body's need for water include exogenous water, fruits, vegetables, and meat. Exogenous water, which comes from drinking fluids and consuming beverages, is essential as it directly provides hydration. Fruits and vegetables contain high water content, contributing significantly to daily water intake. For example, watermelon and cucumbers have more than 90% water by weight, making them excellent sources for hydrating the body. Additionally, certain meats also contain water, aiding in hydration when consumed. Overall, these combined sources ensure that the body receives adequate hydration necessary for optimal physiological functions, including temperature regulation, nutrient transport, and waste elimination.
