Water needs to be considered an essential nutrient. Because of easy access we take water for granted and do not realize the importance of proper hydration. According to experts, water is ranked second only to oxygen as essential for life. Your overall body weight is 2/3 water. A person can survive about two months without food, but only a few days without water.
Water is the most abundant ingredient in the human body through all phases of growth and development. Every system in your body depends on water to function.
Water is an important part of your daily bodily functions, so it is important to continually replenish it. Each day, your body loses 2-3 quarts of water through sweat, urination, excretion and breathing. The body loses even more water if you exercise, live in hot or dry climates, consume high fiber diets, and consume caffeine or alcohol. It is recommended to drink 8-10 cups of fluid a day, adding more water if any of the previously stated situations apply.
Signs of illnesses, such as fever, vomiting or diarrhea, cause your body to lose additional fluids. In these cases, you should drink more fluids and may even need oral rehydration solutions like Gatorade or Powerade. Bladder infections and urinary tract stones also require increased water intake. On the other hand, conditions such as heart failure and certain conditions relating to the kidney, liver or adrenal glands may impair excretion of water and may require a limited fluid intake.
Consuming caffeinated beverages may be a concern because caffeine acts as a diuretic and can cause increased urination. Caffeine is found in coffee, teas, and many soft drinks. Try to drink caffeinated beverages in moderation and focus on consuming more water.
To help increase your water consumption, try:
Do not wait until you feel thirsty. It may already mean that you may be slightly dehydrated
Water is essential to the body in that way.
The vital function that oxygen serves in the human body is respiration. Oxygen is needed for the lungs to function and for the proper functioning of other vital organs such as the heart and brain.
The air bags in your body cavity are called your lungs. These are the organs responsible for providing your body with the oxygen needed for survival.
Nutrient? That would be fat. But if you mean substance, that would be water.
Oxygen is needed by every living cell in your body in order to release the energy needed for life through the process of cellular respiration (ie. "burning" the calories found in glucose, or blood sugar). Without oxygen, cells cannot get energy and they will die.
Oxygen plays a massive role in the human body. Oxygen is responsible for delivering nutrients to the cells in the human body.

Oxygen from the air is needed in the body for cellular respiration. Oxygen serves as the final electron receptor in the Electron Transport Chain, which produces ATP for the body to use as energy.
