Document Summary
Nutrients- components of food that we require for maintenance of life and for growth. Atoms other than carbon, hydrogen, and oxygen that must be obtained from a plant"s environment for photosynthesis to occur. Macronutrients-required in large amounts in our diet and include water, carbohydrates, proteins, and fats. Survival without water is limited to just a few days. Water helps disperse nutrients, dissolve and eliminate waste products of digestion, helps maintain blood pressure and is involved in virtually all cellular activities. Dehydration- decrease below the body"s required water level. Can lead to muscle cramps, fatigue, headaches, dizziness, nausea, confusion, increased heart rate. Severe dehydration can result in hallucinations, heat stroke, and death. Sweating helps maintain body temperature, when water is low, sweating decreases, the temperature can rise to harmful level. A 3% loss in water can cause a 10% reduction in your strength and an 8% reduction in speed.
