It is very important that a person stays hydrated because water makes up more than half of your body weight, and not staying hydrated can result in your body shutting down and possible death. Your body uses water in many ways, all the cells in your body need water to function. All of your body’s tissues need water, and all of your body’s organs need water to function correctly. Some of the ways that your body uses water are ; water is used to regulate your body’s temperature, you sweet to lower your temperature when your body is overheating. Water is also used to carry vitamins and minerals to our body’s cells.
It moves food through and mixing it with digestive secretions from the pancreas and liver. The duodenum is mainly responsible for the continuous breaking-down process, with the jejunum and ileum mainly responsible for absorption of nutrients into the bloodstream.
The monosaccharides are them absorbed into the bloodstream. From blood, the monosaccharides are carried to the liver and converted into glucose and then stored in the liver or sent back out to feed the individual cells. Any fiber continues to the large intestine where some is metabolized by bacteria, but most is excreted. Fat From the mouth, chewing food breaks it down to a degree. The lingual lipase, found in saliva, plays a minor role in breaking down fat.

The digestive system helps break down this food into small pieces, the enzymes within the digestive system breaks the protein into amino acids, fatty acids and carbohydrates into glucose. The sugar, amino acids and fatty acids are able to be used as energy sources in the human by body cells. Energy requirements are ordinarily expressed in terms of calories. The calorie used in nutritional discussions is actually the "large calorie “Calorie. This is really a kilocalorie the amount of heat energy required to raise the temperature of one kilogram (about 1 quart) of water one degree Celsius.
Stops stomach acid from digesting itself 12. Responsible for most food digestion and all food absorption. 13. A. Support the absorption of carbohydrates and proteins B. accept chyme from the stomach and complete digestion C. Absorbs B12,bile salts, fluids and electrolytes and secretes enzyemes that further break down carbohydrates and proteins 14.
P4: Explain the physiology of two named body systems in relation to energy metabolism in the body. Cardiovascular System This system transports materials to the liver and body cells through the bloodstream that is pumped by the heart. Blood Blood is a liquid tissue made up of; plasma, platelets, white and red blood cells and is necessary for every part of the body. The blood contains many different materials and cells and there is fluid called plasma which contains many substances dissolved in it. Plasma carries food from the stomach to cells but carries waste from the cells to the kidneys and intestine.
Water transports nutrients and waste, and is essential for the function of every organ and tissue in the body (Ritz & Berrut, 2005). Water provides cushioning for joints and helps the body regulate temperature (Jequier & Constant, 2010). The human body cannot store the water it needs, so it is important for the consumption
Therefore, they require an energy-dense diet high in protein, fats, and vitamins. Patients also receive additional A, D, E and K vitamins. Poor absorption also hinders patients’ ability to gain weight and to grow normally. However, the most serious impact of Cystic Fibrosis is still breathing. Doctors can recognize Cystic Fibrosis by testing the salt content of the sweat; it is much higher in people with the disease.
SCI/241 THE SCIENCE OF NUTRITION January13,2012 Human Digestion How the does the digestive system works to absorbs nutrients? Digestion starts with the smell of food, it activates the salivary glands. The gland secret saliva that moistens food, it also contains a digestive enzyme called amylase that breaks down some carbohydrates before it leaves the mouth. Then the food is swallowed and goes into the lumen through the esophagus. The esophagus muscles contractions called peristalsis forces the food through the sphincter valve and into the stomach.
