Names: Tyson Tang, Thomas Trayans, Jack Symes-Peschel PCG: 8GO2 Year 8 Biology A Model Intestine Introduction: Appropriate Background Information 1. What happens in the small intestine? The small intestine is mainly involved in the digestion. To help the intestine digest, it requires the use of chemical digestion for it to occur. After digestion occurs, some of the nutrients would be absorbed into the blood stream. 2. What is chemical digestion? Chemical digestion is the process of digestions which
Regulation of bile into the small intestine During the digestive period, intestinal phase signals stimulate the release of bile into the small intestine. This release is regulated by 3 main regulatory factors, secretin, cholecystokinin and gastrin. The liver makes bile continuously. When there is no food in the small intestine, the hepatopancreatic sphincter (the entrance of the common bile duct and pancreatic duct into the small intestine) is closed and the bile backs up into the gallbladder. When
complex, but simple to understand. It involves several steps that include from being chewed inside the mouth, to landing in the stomach for more breakdown, traveling through the intestines, and finally exiting the body. It starts with a process called mechanical digestion. It is when food is chewed in the mouth and turned into small pieces, then is swallowed. The tongue is a muscle that helps push back food toward the back of the throat. Salvia aids with the smooth ride the food takes going down to the
Large intestine is responsible for the process of waste this can emptying the bowels. Large intestine also are made up with the cecum. Rectum is a chamber that contain around 8 inch of tube, the rectum are connected to the large intestine and anus. Rectum have a function of release the unnecessary product. Ingestion is a process of consuming any product alimentary into
food. The main pancreatic duct runs the length of the pancreas and drains the fluid into the duodenum which starts the first part of the small bowel. The small intestines is where the most absorption begins. It modifies digestion and absorption. The small intestines mechanically breaks down and propulsion. The Segmentation by the smooth muscle of small intestines continues to mix contents with digestive juices. When absorption begins it breaks down
In anatomy, sphincter is the name given to an annular muscle located in the orifice of a body cavity, and whose function is to open and close, preventing or allowing the passage of a substances (such as secretion) outside or into the cavity. This way, the sphincter may close to retain substances within the body or a specific body organ, or may open allowing these substances to pass from one organ to another, or to be expelled from the body. According to several specialized publications, there are
A good portion of the microbes in the large intestine helps the process along with the digestion process. The large intestine is called the cecum. The cecum, which connects to the colon, is divided into four pieces. The ascending colon, the transverse colon, descending colon and the sigmoid colon all four colons form an inverted u-shape
bread and peanut butter enter the stomach, salivary amylase is then inhibited by HCL. The food then moves to the small intestine (duodenum), where pancreatic amylase furthers the process of digestion. Brush border enzymes then digest the disaccharides, trisaccharides, and alpha dextrins in the small intestine. The major site of absorption of carbohydrates occurs in the small intestine along microvilli (brush border). Located along the brush border are monosaccharide transporters. Carbohydrates are
carbohydrates that are indigestible to digestive enzymes in the gastrointestinal tract (GIT) of mammals. The simplest definition of dietary fiber is that it is composed of plant derived polysaccharides that are not degraded by digestive enzymes in the small intestine of monogastric animals (Urriola, 2016; Hunag et al., 2016). The variation of ingredients in overall dietary fiber including crude fiber, neutral detergent fiber, acid detergent fiber, and the total dietary fiber content are what create the physiological
Imagine, being born with your intestines hanging out of your belly. Sounds painful and uncomfortable right? "About 2,000 babies are born with gastroschisis each year in the United States" (Gastroschisis. (n.d.). Retrieved May 9, 2014, from http://www.cardinalglennon.com/fetalcareinstitute/conditions/AbdomenIntestines/Pages/Gastroschisis.aspx). Thats about 1 in every 5,000 babies born, not rare, but fairly uncommon for it to be seen in children. Most are born prematurely, but are often delivered
exiting the small intestines, the remaining contents enter the large intestine which is responsible for the absorption of water from the food/waste product by the use of Vitamin K and B while not extracting so much as to create a problem with excretion, this being constipation when too much water is extracted making exertion harder or diarrhoea which is caused when not enough water is removed leaving a large amount of liquid in the waste faecal matter. At the entrance to the large intestine there is
The Detail Digestion Process & Body Absorbs of Nutrients Digestion is the chemical breakdown of complex biological molecules into their component parts, i.e. lipids into fatty acids, proteins to individual amino acids, and carbohydrates into simple sugars. The functional objective is to produce various chemicals to break down the food, filter out harmful substances when possible, and get rid of solid wastes. The mechanical way the digestion works in order to change the physical form of the food is
cellulose of the undigested particles. It continues on to the descending colon. There I start to manufacture vitamin K and other B-complex vitamins. Those are then absorbed into my large intestine. The waste of my "ham" sandwich keeps going. The haustra removes any excess water that was not absorbed in my small intestine. It doesn’t have to do much work, because there is hardly any area for absorption. The waste then travels down my sigmoid colon to my rectum. There the waste, now called fecal matter
release stored sugars back into the bloodstream. Pancreas produce enzymes which is protein such as amylase, protease and lipases. It used to speed up the biochemical reactions and helps to digest macromolecules into much smaller molecules so the intestines can absorb them easily. Amylase is divide carbohydrates or starches to create energy-rich sugars such as glucose. Protease is helps to splits up proteins into amino acids. Lipases is helps break down fatty substances. Digestive enzymes are so strong
The digestive system is made up of several organs that all work together so that the body can get the energy it requires to go about its daily tasks. The initial way the gastrointestinal (GI) system does this is by breaking down the food we eat into smaller and smaller pieces so that the body can use the energy from the food to help repair and build new cells. The pathway that the food takes to go through the body is called the gastrointestinal tract. The GI tract is a series of organs that begins
Identify and describe the six major processes involved in gastrointestinal activity. The six major processes involved in gastrointestinal activity include: ingestion (substance enter the oral cavity of the digestive track), mechanical processing (mastication consist of chewing/breaking down the substance and peristalsis consisting of involuntary contraction that assist the movement of food through the esophagus and intestinal tracts), digestion (chemical break down of substance into smaller fragments
The pancreas is the organ of the upper part of the abdomen that is about 6 inches long . The flattened head of the pancreas is surrounded by part of the small intestines called the duodenum and the body lies behind the stomach with the rest of the tail in front of the left kidney. The main functions of the pancreas is to secrete alkaline juice with enzymes, amylase and lipase, and secrete insulin and glucagon. Amylase and lipase helps diges t fats, protein, and carbohydrates from food
What do they mean when they say digestion starts in the mouth? What they mean is the process starts in the mouth which is known as mechanical digestion whereas the food is broken down into smaller pieces. Your mouth has teeth that can grind, chew, and tear different kinds of food. But your tongue helps in the aid of efficient mechanical digestion by being able to move the food around in your mouth and by mixing it with saliva to help break the food down easier. Why is it important to include fiber
The gallbladder is inferior and posterior to the liver. The gallbladder and its connecting ducts are referred as the biliary system. The biliary system is involved in the production and transportation of bile2. Bile is produced in the liver and when it is secreted, it flows through the cystic duct to the gallbladder to be stored. The gallbladder is a storage unit for bile. The job of bile is to emulsify fat. Also in the gallbladder, hard deposits of bile can form. Those hard deposits are called gallstones
What is Pharmacology? Pharmacology is the study of the interaction of drugs with living organisms, such as humans, animals and even microorganisms. Pharmacology also includes sources, adverse effects, absorption, physiological factors, biotransformation, dosage forms, methods of administration, excretion, and history. So, what are drugs and what exactly do they do? Drugs, also known as narcotics, are chemicals that alter functions of living organisms. They are generally given for the diagnosis,
