Why Food Groups

The esophagus receives food from the mouth after swallowing and then delivers it to the stomach. The stomach holds food which it is being mixed with enzymes which continue the process of breaking down the food into a useable form. When the contents of the stomach are processed they are released into the small intestine. In the small intestine food is broken down by enzymes released from the pancreas and bile from the liver, the food is moved through and mixed with digestive secretions. The small intestine is made up of three segments the duodenum, jejunum and the ileum, the jejunum and the ileum are mainly responsible from the absorption of nutrients in to the bloodstream. These contents start out semi-solid and end in a liquid form after passing through the organ. Water, bile, enzymes and mucous change its consistency, one the nutrients have been absorbed it then moves onto the large intestine. The large intestine connects to the rectum and is specialised in processing water so that emptying the bowels is easy.

Food constitutes the rudimentary needs of humans in order to survive. They provide nutrients such as carbohydrates, proteins, vitamins and minerals that nourish cells, supply energy and rejuvenate tissues in the body which promotes growth and development of a person.

Villi and microvilli separate the food particles, which is a physical process. Enzymes are also dumped from liver, gallbladder, and pancreas to help with digestion. Small intestines are divided into three sections; duodenum, jejunum, and ileum. The duodenum produces intestinal enzymes that help to break down nutrients more efficiently in order to ease their absorption in the jejunum and the ileum. Peristaltic contraction plays a great role in moving chyme to the large intestine from the small intestines. Large intestines is comprised of three segments; the cecum, the colon, and the rectum. Food is received in the cecum from small intestines and proceeds into the colon where water is absorbed, and undigested materials are converted into feces. Peristalsis receives the food from colon and stores them before they are expelled through the

When eating a meal the gallbladder then contracts which sends bile to the small intestine. Then the nutrients gets absorbed into the blood stream, there is leftover liquid that passes into the small intestate. What food that is left over then travels to the large intestine. “The large intestine is a 5-6 foot long muscular tube that connects the cecum which is the first part of the large intestine to the rectum and the last part of the large intestine”. The large intestine is made up of the cecum, which is the ascending right colon, the transverse colon, the descending colon, and the sigmoid colon, that connects to the rectum. Stool, or waste left over from the digestive process, is passed through the colon by means of peristalsis, first in a liquid state and ultimately in solid form as the water is removed from the stool. A stool is stored in the sigmoid colon until there is a movement to release the stool into the rectum twice a day. When the descending colon becomes full it then empties the contents into the rectum. The rectum is an 8 inch chamber that connects the colon to the

In what form are potatoes easiest to digest, raw, cooked, or cooked and cooled? If a potato has been cooked, then it will break down more starch molecules making it easier to digest. The body starts digesting food as soon as it enters the mouth.

The 3 parts of the small intestine are responsible for the transfer to happen. The duodenum breaks down chyme from the stomach with the help of the pancreas and gallbladder. The jejunum has villi that help transfer vitamins & minerals into the bloodstream. The last section is the ileum that transfers the remaining nutrients to the blood via

In order for our bodies to function properly, we need to consume macro- and micronutrients. Carbohydrates are major macronutrients. In order to utilise Carbohydrates, our body needs to digest them. This happens in a sequence of events.

Then we have the esophagus, where there is secretes mucus to help w/ lubrication, allowing food to continue moving down esophagus. The small intestine instead contains brush border, folded mucosal tissue (villi) that enhances absorption. The brush border contains "brush border enzymes" - final stage of chemical digestion in digestive tract. The large intestine Contains intestinal flora bacteria and moves food toward rectum. The digestive enzymes instead are: Pepsin (ogen) enzyme breaks down proteins; pepsinogen becomes pepsin once comes in contact w/ HCl. Pepsin is enzyme that actually breaks down chime. Gastric lipase enzyme, which breaks down fats and the Intrinsic factor that facilities absorption of Vitamin-B12, necessary for cell mitosis. Then we have carbohydrates, which When its consumption is inadequate, protein is broken down to make glucose to maintain a constant blood glucose

The six different nutrients are protein, carbohydrates, fats, vitamins, minerals, and water. Protein have the building of the body, and not just for the muscle. Every cell, from bone to skin and hair, contains protein. Carbohydrates are necessary for a healthy body. Carbs fuel your body, especially your central nervous system and brain, and protect against disease, according to the Mayo Clinic. Fats often get a bad rap, but recent research has shown

The gastrointestinal system allows for an intake of substance and extracts the nutrients from the food. The substance that is not absorbed by the body is then expelled as waste (Wallace 2013). The Gastrointestinal System starts at the mouth primarily with mechanical digestion. It then follows a hollow tube called the esophagus, which serves as a connecter into the stomach. The stomach continues to mechanically churn the bolus, but also takes part in the chemical breakdown of proteins (Bolus 2016). From the stomach the chyme enters into the small intestine. The small intestine is comprised of three sections: the duodenum, jejunum, and ileum. The small intestine is important for breaking down carbohydrates and fats, but also begins to absorb the nutrients for the body (Gastrointestinal tract 2013). Whatever is not absorbed by the small intestine then moves to the large intestine, where vitamins and water are absorbed. The large intestine is made up of the cecum, colon, and rectum to finally be passed out through the anus (SEER 2016). All wastes are then expelled out of the body.

The pharynx acts as a passageway for food, fluids, and air. The esophagus is a muscular tube that carries food to the stomach. The stomach is a temporary “storage tank” where chemical breakdown of proteins begins by using pepsin and HCl. Absorption is also taken place in the stomach because the stomach can absorb a few fat-soluble substances such as aspirin, alcohol and some drugs. The small intestine is the body’s major digestive organ and within its passageways, digestion is completed and virtually all absorption of carbohydrates, proteins, lipids and nucleic acids (also vitamins, electrolytes, and water are absorbed). The large intestine digests remaining food residues by using enteric bacteria. The large intestine also absorbs most of the remaining water electrolytes (mostly NaCl) and vitamins produced by bacteria, propels feces toward rectum by haustral churning and mass movements and defecates. The mouth is the beginning of the digestive tract (ingestion) as food is voluntarily placed into oral cavity. Salivary amylase in saliva produced by salivary glands begins chemical breakdown of starch. Lipase begins chemical breakdown of lipids. The bolus then goes to the pharynx which is also known as the throat where deglutition(swallowing) occurs. During deglutition in the pharynx there is a flexible flap of elastic cartilage that’s function is to keep food out of

The electron micrograph image above shows epithelial tissue within the intestines. The role of the intestines is to absorb nutrients from the food and drink we ingest and to absorb water from food. The lining of the small intestines is covered with microvilli. Microvilli are microscopic hair-like structures which produce a larger surface area for the absorption of nutrients. Each microvilli contains a small blood capillary. When nutrients are absorbed into the hair-like structures, they enter its blood capillary. As there are so many microvilli structures on the lining of the small intestines, it creates a brush border. This helps the absorption of nutrients. This is how the nutrients are transferred from food into the bloodstream. Goblet cells

The small intestine absorbs most digested food molecules, as well as water and minerals, and passes them on to other parts of the body for storage or further chemical change. Hormone and nerve regulators control the digestive process.

When food is put in the mouth, the teeth grind it up into a paste and the amylase in the saliva begins to break down the carbohydrates. Swallowing takes the food into the oesophagus and by peristalsis moves it into the stomach. In the stomach, strong hydrochloric acid breaks down complex proteins over a period of a few hours. The resulting mixture then moves into the small intestine, the start of which is called the duodenum. Here, bile from the liver and enzymes from the pancreas mix into the food. As the mixture moves down the small intestine, the enzymes

Abortion of nutrients and fluids occur in the small intestine most all of the time but also a little bit in the large intestine. The structures needed for absorption are obviously the small intestine and also the large intestine. It requires the lumen and also pancreatic enzymes for the small intestine and mucosal enzymes for the large intestine. Proteins, vitamins, carbohydrates, lipids, starches are just a few example of nutrients that are absorbed into the blood. The nutrients that are most often absorbed in the lymph are those called fats.
