Kaylee Angeline Garcia Mr. Balleweg Theory of Knowledge June 2014 Extended Essay Topic: Alternative Uses for Urine Research Question: With the technology we have today, can urine become more than just a waste product? Approach: An essay that examines the use of modern technology for the transformation of urine to water and fuel. Through several experiments and observations it has been calculated that the average man can live up to about three weeks without food, yet can only live up to three days without water. Why is this so? Water is the most essential substance to humans when it comes to survival, for tt is the substance that keeps our body working properly and efficiently, and it has been purifying the human body ever since man was created, serving as a lubricant. Not only that, but water regulates our body temperature, and maintains our body stable and healthy. Essentially, water is so crucial to our survival that about ninety five percent of our brain eighty two percent of our blood, and even ninety percent of our lungs are made up of water and since the human body is about two thirds water, it has been estimated that nearly 1 x 10^27 or 10,000,000,000,000,000,000,000,000,000 water molecules flow through our bodies daily. Thus, it is necessary for the average human to consume a sufficient amount of water. On Earth alone, about seventy five percent of the earth is covered in water, yet a majority of that calculation is known to be saltwater: water we cannot drink or
The body needs to maintain equilibrium to function properly in everyday life. The most important substance it must regulate is water; water is everywhere in our body and its balance is essential for proper body function.
It is also important to know that the body is constantly losing water through perspiration, respiration and urination. Therefore, it is imperative that the body's supply is replenished. Besides basic needs, the more calories that the body burns the more water the body needs. Research suggests that a person needs one tablespoon of water for every calorie burned. Since the average person burns about 2,000 kilocalories a day, eight glasses of water should be consumed daily to maintain a healthy balance.
The human body consists mostly of water, and is a major constituent to the human body and vital organs; of this 90% include blood plasma, lymph, urine, saliva, digestive juices, bile, cerebrospinal fluid and tissue fluid. Water enables substances to be transported throughout the body, red blood cells for example, as wells as supplying the medium required for metabolic reaction to take place (respiration). Without water the progression of these fluids would not be possible. Water is constantly being transported between the fluid compartments of
Water is the most abundant compound in the human body. Water is ESSENTIAL for the process of homeostasis. Water increases the volume of blood which in result affects blood pressure and the heart rate. Also, if there is a drop in blood volume there is also a drop in the blood pressure. This then triggers us to become thirsty, and drinking water increases the volume again stabalizing the body.
Water is essential for life as we know it on earth. It is used by plants
Water is one of the most important elements on Earth and also for our body. We need water to work and function properly and well. Without enough supply of water, our body will grind to a halt and collapse.
Water is just as important as air, it is a basic need for life, ever since the
It’s hard to believe that something without color, taste, or smell could be so important for survival and that resource is water. Water is a resource on planet earth that is needed for humans, plants, and animals for survival, without it nothing would live everything would die. The human body weight is about 60 percent of water. Not only do we need water when the body sends a message that it is thirst it keeps every tissue in the body moist, and aids in the protection of the spinal cords and our joint. It is needed for the digestion and the transporting of waste from the body. Each organ in the body contains a percentage of water the liver 71%, bones 31%, lungs 83%, skin 64%, heart 73%, teeth tissue 10%, kidney 79%. Water is an important
Water is considered as an essential for human existence. We all can survive without food for some day but no one can live without water at least two days. Human body consists of 70% percent of water and our globe is covered by 69.9% percent of water. But unfortunately the useable fresh water is just 2.5% out of it. Water is a social good, water is an economic good, water has ecological value and water has religious, moral and cultural value.
Upon research it was due to the fact that food stays in the body much longer than water. Our bodies can generally store unused food that we eat in fat and protein stores. Unfortunately, we do not have the same ability to store water like we do food for a long period of time. “Water brings life; life needs water.
Water covers about two thirds of the total surface of Earth, but most of that is saltwater. Humans must drink freshwater to live. 97% of the water on Earth is saltwater, while only 3% of Earth's water is freshwater. And 70% of the freshwater is ice in glaciers, ice caps and permanent snow. The small amount of freshwater remaining is distributed for use to the Earth's 6 ¾ billion people for agriculture, industry,
Hydration with water and other water-based liquids is critical for survival and functioning of the body’s organs. Water is 60% of the total human body composition. Water is involved in the
The purpose for the water/food supply is to know how important it is to humans and animals and how we can save our water/food supplies before it is too late. Having an abundant supply of clean water and healthy food are top needs in an emergency. An ordinarily active individual needs to take not less than two quarts which is equivalent to half gallon of water every day. Water consumption on drinking may depend on the environment, level of health and other factors. Similarly, people living in hot environments, nursing moms, children and sick individuals will drink much more. Water is required for various other reasons food cooking and cleaning.
Apart from supporting hydration and preventing dehydration, water has a number of essential roles in our body. Here is a detailed overview.
Water is our main source of our life. We need it to live, drink, bathe,
