Recommended: Digestive system question and answer
The digestive system process begins at the mouth and finishes at the anus. This system includes the mouth→ pharynx→ salivary glands→ larynx→ oesophagus→ stomach→ liver→ pancreas→ duodenum→ small intestine→ large intestine→ rectum→ anus. Digestion is the breakdown of food that allows the body to absorb the food into the bloodstream and into the cells for energy. This happens mechanically and chemically, mechanically means by your teeth, tongue and gums so chewing food. Whereas chemically means by the digestive enzymes; amylase, protease and lipase. Each part of the digestive system have an individual role/function; The mouth is where digestion begins and the mechanical breakdown of food takes place. This is because the food is chewed and then …show more content…
The bile that is made in the liver travels to the small intestine by the bile ducts (these are small, tube-like structures where they carry bile from the gall bladder and empty it into the first part of the small intestine, called the duodenum). However, if the small intestine doesn’t need the bile, it will enter the gall bladder where it waits for a signal from the intestines that the food is present. Bile→ This has 2 main purposes, firstly, it helps to absorb any fats in the diet and secondly, it carries any waste that’s from the liver that can’t travel through the kidneys. The pancreas is the chief/main factory for all of the digestive enzymes and they are secreted in the first segment/part of the small intestine. The enzymes break down proteins into protease, fats into lipase and carbohydrates into carbohydrase. Also, the pancreas produces insulin which is responsible for controlling the blood sugar and then it is secreted directly into the bloodstream. Insulin is the main/chief hormone that metabolizes …show more content…
Peristalsis that was mentioned earlier in the oesophagus is also used in the small intestine to help move food through and mix it with digestive secretions from the pancreas and the liver. Its first responsibility is the process to continuously breakdown, then the second and third responsibility is the absorption of nutrients into the bloodstream. As chyme moves through the small intestine, many of the molecules are absorbed in to the bloodstream and the small intestine has a very efficient way to help in this process. The inside of the small intestine has finger-like projections called villi and these raise the surface area of the gut. The contents of the small intestine begin semi-solid and then finish in a liquid form after passing through the organ. Bile enzymes, water and mucus contributes to the change in consistency. Then once the nutrients have been absorbed and any leftover food residue liquid has been passed through the small intestine, it will then move onto the large intestine through the ileocecal
Gallstones form when the liquid stored in the gallbladder hardens into pieces of stone-like material. The liquid, called bile is used to help the body digest fats. Bile is made in the liver, and then stored in the gallbladder until the body needs to digest fat. At that time, the gallbladder contracts and pushes the bile into a tube—called the common bile duct—that carries it to the small intestine, where it help with digestion.
•The forty five year old patient is diagnosed with the progressive cirrhosis inflaming the liver along with the parenchymal cells. The plain symptoms is manifested primarily because of the augmentation of edema internally in the lower abdomen.
The dog’s small intestine is split in to three parts. The first part is called the duodenum, in here chemical degradation of chime starts in here. It is caused by the enzymes which are secreted by the duodenum and the pancreas. Bile; which is produced by the dog’s liver and stored in to the gallbladder; helps to break down the fats and help to neutralise acid which was from the stomach. The second and third part of the small intestine for the dog is the jejunum and ileum. The jejunum and ileum surface area increase due to the plica circulares; this is circular folds; which carry villi. Each one of these villi’s has a capillary and a lymphatic capillary (lacteal), this absorbs the digested food through rich venous and capillary drainage of the gut. Whereas the horse’s small intestine are the major organ in their digestion system. They are 70 feet long and can hold up to 12 gallons. In their small intestine pancreatic enzymes help to digest their food. It will digest starches, digest sugars and carbohydrates. In there is also protease which help to emulsify proteins in to amino acids. The horse does not have a gallbladder like the dog does; this mean the bile constantly flows in to their small intestines. The bile helps to break down fats and to suspend the fats in the water. The food then which has be digested will be absorbed through the walls of the small intestine and carried through the blood stream to
Solubilisation and transport of lipids (in an aqueous environment): acids within the bile are lipid carriers and are able to make lipids more soluble by forming micelles (making a lose structure of particles in this case...
Our chicken sandwich has, by now, been broken down into digestible nutrients. The pancreatic juices have broken down the carbohydrates in the bread into monosaccharides (such as glucose and galactose) which leave the enterocyte by facilitated diffusion and enter the rich network of capillaries. They are transported in the blood stream and cross into the cytoplasm by Na+ cotransporters. Amino acids are moved to the circulation by facilitated diffusion. Lipids from the butter are broken down into fatty acids by lipases and are then absorbed across the cell membrane into the cytosol where they are reassembled into lipoprotein particles called chylomicrons. These are carried through lymphatic channels and into the circulation via the thoracic duct. The bloodstream carries simple sugars, glycerol, amino acids, and a number of salts and vitamins to the liver. The lymphatic system, a network of vessels that carry white blood cells and lymph fluid throughout the body, absorbs fatty acids and
The digestive systems functions are to digest food, absorb any end products that were digested (including vitamins and minerals). The physiological processes of the digestive system are ingestion, propulsion, mechanical breakdown, digestion, absorption and defecation. Mechanical digestion means to use force in order to break down food for example the use of chewing or the contraction of muscles. Chemical digestion is when the food is broken down chemically into smaller particles such as the use of the saliva in the mouth.
This pear shaped organ contracts while we eat, then sends bile to the small intestine (WebMD (2).)
...ve eaten, to break down the food into a liquid mixture and to slowly empty that liquid mixture into the small intestine. Once the bolus has entered your stomach it begins to be broken down with the help of the strong muscles and gastric juices which are located in the walls of your stomach. The gastric juices are made up of hydrochloric acid, water, and mucus- and the main enzyme inside of your stomach is what is known as pepsin, which needs to be surrounded in an acidic setting in order to do its job, that is to break down protein. Once the bolus has been inside of your stomach for long enough it begins to form into a liquid called chyme, and what keeps the chyme from flowing back into our esophagus are ring shaped muscles known as sphincters located at the beginnings and ends of the stomach and they have the task of controlling the flow of solids and liquids.
Imagine you are eating a sandwich containing wheat bread, ham, lettuce, and Swiss cheese. Do you ever wonder where the nutrients go from all of the previous listed ingredients? Well, when a bite of this sandwich is taken, the mouth produces a saliva enzyme called amylase. This enzyme immediately goes to work by breaking down the carbohydrates that are in the bread. Once, the bite is completely chewed, the contents then are swallowed and go down the esophagus and begin to head towards the upper esophageal sphincter and the is involuntarily pushed towards the stomach. The next passage for the sandwich is to go through the lower esophageal sphincter; which transports the sandwich into the stomach.
In short, digestion is the process where food is broken down and then absorbed by the body. The digestive system is extremely important as it is the main factor in how much of a foods nutrients are utilized. The process of digestion is essential for the body as it is the body's source for energy.
The digestive system is important for breaking down food and turning it into nutrients. The body uses the nutrients for energy, growth, and cell repair. The food and drinks that a person must be changed into smaller molecules of nutrients before the blood absorbs them and carries them to cells throughout the body. The body breaks down nutrients from food and drink into carbohydrates, protein, fats, and vitamins. Compared to the other systems in the body, the digestive system is one of the most diverse and important. According to Robert Sullivan the digestive system is a set group of organs whose function is based on the process of turning food, absorbing nutrients for energy and getting rid of the bodies waste (Sullivan, 2008, p.33). The organs
As the digestive system breaks down your food, after it's broken down it turns into energy. Your circulatory system takes some the produced energy and transports it around the body, delivering it and other blood, nutrients, oxygen, and more compounds to every cell in your body. The digestive depends on the circulatory as much as it does vice versa because they need the blood, nutrients, and energy (broken down food) that was produced from both systems. Many digestive organs need to use about 30% of cardiac output. Both the digestive and circulatory systems get rid of unwanted or unneeded materials (waste) and feces (poop). The vial substances are absorbed by the small intestine, where it is put into the bloodstream, so it can be circulated around the body. The most important thing is that with no nutrients and circulation, there's no life.
During digestion, the body breaks down food into smaller molecules that could then be used by the body’s cells and tissues in order to perform functions. This starts off in the mouth with the physical movements of chewing and the chemical breakdown by saliva. Enzymes in the stomach break food down further after traveling from the mouth through the esophagus. The food from here then moves into the small intestine, where pancreatic juices and enzymes dissolve proteins, carbohydrates, and fibers, and bile from the liver breaks down fats into these small molecules. Any portion of the fibers or food that were unable to be broken down are passed from the small intestine to the large intestine, which is where the digestive tract transitions into the excretory tract, then the colon and out of the rectum. Any liquids that have been stripped of their nutrients by the body proceed from the stomach to the kidneys. In the kidneys, sodium ions (Na+), uric acid, and urea are exchanged with water, which moves urinary bladder and is excreted through the
Absorption is the way of digesting the food molecules into the small intestine. This process of absorption pass throughout the wall of the small intestine into the bloodstream. The bloodstream carried out all important nutrients to the
The digestive system is a very important system in the human body. It is a group of organs that work together to turn food into energy and nutrients in the entire body. The food that was chewed in a humans’ mouth now passes through a long tube that is inside of the body that is known as the alimentary canal. The alimentary canal is made of the oral cavity, pharynx, esophagus, stomach, small intestines, and large intestines. Those few things are not the only important accessories of the digestive system there is also the teeth, tongue, salivary glands, liver, gallbladder, and pancreas.
