Problem 3.

  1. Define nutrition and condition its importance

Nutrition is the foundation of minerals and vitamins within food that is necessary by microorganisms to ensure their healthy progress and survival. A variety of nutrients are needed to ensure that the the different parts of the body i. e. , its skin cells, tissues and organs are healthy. If the body is with no sufficient supply of nutrients it'll be unable to carry out any of its metabolic, physical, mental of chemical type functions. The simplest way in which to receive these nutrients is through food.

  1. Identify the types of nutrients and status the nutritional requirements for each and every age group


  • Water

This is the most important nutrient as the body is made up of around 50%-55% drinking water. It is used by your body all day and it manages the heat of your body to releasing high temperature. Water is the medium where nutrients are transported to body's skin cells as well. The daily requirement of normal water varies from individual to individual as you have to consider heir degree of physical activity. For example, somebody who sits at a table all day will not need just as much water as building employee who works in sunlight all day.

  • Carbohydrates

Carbohydrates are the primary way to obtain energy for the body as it powers the mind, muscles, organs and heart. When a person eats about 2, 000 calorie consumption each day, then that person should eat about 250 grams of glucose each day.

  • Protein

Protein is the building blocks for the tissuies of the body as they give it its structure and also bring other essential elements to the blood's cells. Protein requirements are difficult to gage because the number varies with time. Matching to WebMd:

Infants need approximately 10 grams per day.

Adult men need about 56 grams per day.

Adult women need approximately 46 grams per day.

  • Fats

Fats (animal excess fat) and unsaturated excess fat (vegetable excess fat) are the two main kinds of fat. According to the Daily Intake Guide, the research value for fat for the average adult is approximately 70 grams while the research value for saturated fat for an average adult is 24 grams.


Vitamins are needed for the proper performing of the body. Lots of the vitamins essential for our health cannot be made by our bodies. We should thus ensure that we obtain them from a proper diet.


Minerals, which can be within one's diet, are compounds that join along in a variety of ways to produce the structures of the human body.

  1. Identify the organs of the digestive system
  • Mouth

This is the start of the digestive system. The process of chewing takes place here to ensure that the meals is destroyed into tiny pieces for easy digestion. Saliva, created from the salivary glands in the oral cavity, combine with the meals to start the procedure of digestive function.

  • Throat

This is also known as the pharynx and it is from that food techniques to the esophagus.

  • Esophagus

This is a pipe made of muscle that spreads from the pharynx to the stomach. In the action of peristalsis, which is a group of contractions, the esophagus transports the chewed up food to the stomach. Prior to the food reached the belly, is passes through a valve known as the low esophageal sphincter which is a region of ruthless. This valve helps prevent food from going back up in to the esophagus.

  • Stomach

This can be an body organ that is very sac-like with durable muscular wall space. Its houses the meals and grinds and mixes it. The tummy releases acid solution and enzymes that are necessary for breaking down the meals. When this food leaves the tummy it is no longer is small chunks but it now takes on a water or paste steadiness. This liquid of paste then trips to the small intestine.

  • Small Intestine

The small intestine has three parts: the duodenum, jejunum and ileum. It is a pipe long long that gently coils in the stomach. The breakdown of food is continuing in here through enzymes that are secreted from the pancreas and the bile secreted from the liver. Bile is used to digest extra fat and be rid of waste material found in the bloodstream. The action of peristalsis also occurs here to ensure that the food is blended well with the different intestinal secretions. The function of the duodenum is to keep the breakdown of the food while the jejunum and ileum are in charge of absorbing the nutrition from the food into the blood stream of your body.

  • Pancreas

The pancreas release enzymes in to the small intestine to break down fat, health proteins and carbs from the meals we ingest. It is large in size and found inferior and posterior to the belly.

  • Liver

The main function of the liver in conditions of digestive function is release a bile which cleans and purifies the blood containing the utilized nutrients that originates from the tiny intestine.

  • Gallbladder

The function of the gallbladder is for storage area of bile and recycling of extra bile from the tiny intestines. Is fairly small, pear-like in condition and found posterior to the liver.

  • Large intestine

This is an extended and thick tube which functions to soak up water and breakdown the wastes to get small helpings of nutrients using its symbiotic bacteria. Feces are the final end result and it leaves your body though the anal passage.

  1. Explain how healthy uptake in a healthy individual differs from someone who has Crohn's disease

The diet of a person who has Crohn's disease is dependant on avoiding certain cause foods that normally triggers flare ups in the disease. Crohn's disease hampers the absorption of nutrients; it is therefore essential a high calorie and high protein-diet is adopted. A person experiencing the disease must have regular means in addition to two or three snacks every day to acquire sufficient nutrients. Vitamin supplements and nutrient supplements are also recommended to obtain the needed nutrients in the body. Some foods which should be prevented if you have Crohn's disease are alcoholic beverages, milk products and spicy foods. Some foods that are best for the condition are almond milk, eggs and oatmeal.

A deficit disease is induced by having less a certain supplement or mineral is the diet of the organism. Nutritional diseases are because of this of a insufficiency in a person's diet.

  1. Explain the role of the liver organ in the metabolism of nutrients

The role of the liver is in the break down and absorption of nutrition in to the body. It gets the intestinal products by sugar, fatty acids, glycerol and proteins. The breakdown of carbs, proteins and extra fat occur in the liver organ even though there are exact roles completed by the fat depots and the muscle of the skeleton. The finish products of the metabolism are stored in the liver which is utilized if needed down the road. Liver skin cells, called hepatocytes, comprise of many enzymes necessary to complete important metabolic functions. In case a nutrient is by the bucket load or if the level are low in the body determine how the hepatocytes offer with the nutrition. The hepatocytes change their metabolic pathways to suit the circumstance.

  1. What is the role of the Peyer's Areas in the immune system system

Peyer's Patches provide to guard the mucous membranes of the tiny intestine from any kind of infection. These are bundles of lymphatic tissues which are round in form, comprising of unencapsulated lymphatic cells. The entire function of the lymphoid tissues is to release the T cells and B skin cells to the site of an infection so that the Peyer's patches can come into action and protect the inside of the intestine. The Peyer's areas also prevent bad area effects that may damage the inside of the tiny intestine by moderating the immune system response.

  1. Explain the effects of the medications applied to the GI tract.
  • Mesalazine

Mesalazine prevents swelling in the bowel and works mainly in the gut as a bowel-specific aminosalicylate medication.

  • Paracetamol

Paracetamol relieves pain and palliative look after those with bowel pain in their gastrointestinal tract.

  • Azathioprine

Azathioprine snacks prevents bloating in a bowel disease.

  • Prednisolone

  • Calcichew D3 Forte
