Document Summary
Intro to nutrition: chapter 9 nutrients involved in fluid balance. Liquid substance in which other substances dissolve: 50-70% of the human body is water. Medium for chemical reactions of human metabolism. Temperature regulation: water temperature changes slowly because of its ability to hold heat, overheating: dangerous water is secreted in form of perspiration which evaporates through skin pores and cools the boy at the same time. Integumentary system: for every one quart or two pounds loss of perspiration, approximately 600 calories of energy have been lost through the skin and other tissues. Hydration is a huge issue for athletes and those in warm climates. If you are unable to perspirate, death is likely to occur. Water moistens, lubricates, and cushions: secretions made in the digestive tract, respiratory tract, urogenital tract, eyes, and skin. Mucus mouth to lubricate food to pass through esophagus, coats stomach from acid.
