Organic acids, containing carbon, oxygen, wind hydrogen, that are constituents of fats and oils. There are more than 40 fatty acids found in nature, they distinguished from are another by their consistent numbers of carbon and hydrogen atoms, Certain fatty acids cannot be synthesized by body and mush by provided by the diet, these substances, sometimes collectively turned essential fatty acids, are linoleic, linolenic and arachidonic acids, strictly speaking only linoleic acid is truly essential, because the body can make the other two from linoleic acid obtained from food…..
A general term describing the accumulation of fat within the cells of tissues damaged by disease,
A condition in which fat accumulated within the liver cells, The most common cause of fatal liver is excessive consumption of alcohol which, if continued eventually leads to a cirrhosis. However, if the drinking of alcohol stops, the fat clears from the liver, Fatal liver can also occur in association with obesity, diabetes mellitus, starvation and in some cases of chronic ill-health.
Feverish or related to fever, Febrile convulsions, for example, occur mainly in young children with high main temperatures.
A self-regulating mechanism that controls certain body processes, such as hormone and enzyme production, if for example, levels of a hormone are too high, output of any substance that stimulates the hormone’s release is inhibited.
YOUR BODY: FEEDBACK MECHANISM
Feedback mechanisms regulate hormone secretion in order maintain correct levels of substances in the blood, for example, a drop in the calcium level in the bloodstream stimulates an increase in the secretion of parathyroid hormone (PTH) which acts on various parts of the body to raise calcium levels. When calcium reaches the normal level. PTH secretion decreases.
hormone production ( negative feedback) The reverse process restores the balance if the levels of a hormone become too low, (See box above and also the endocrine system,
The administration of nutrients other than by mouth usually by way of a tube passed through the nose into the stomach or small intestine. If long-term artificial feeding is anticipated a tube is inserted directly into the stomach or upper small intestine during endoscopic surgery. This is called enteral feeding. If the gastrointestinal tract is not functioning, nutrients must be introduced directly into the bloodstream. This type of feeding known as parenteral nutrition
Tube feeding may be necessary for people who have difficulty swallowing, or gastrointestinal disorders, for example, conditions resulting in malabsorption, or disorder affecting the nervous system or kidneys. Premature babies often require tube feeding if their sucking reflexes are undeveloped, as do critically ill patients due to their increased nutritional requirements. Food mixtures, or preparations of nutrients, are given through a tube that passed through the patient’s nostril and down to the stomach or duodenum, There are two methods of feeding, continuous drip feeding, and bolus feeding (in which set amounts of nutrients are given at regular intervals throughout the day). In both methods, the rate of delivery of the food can be controlled by a pump.
