When food is broken down in the stomach, it forms a substance called chyme which is a slurry of nutrients. The cells of the villi and another part of the small intestine, transport food from the digestive tract into the bloodstream, where they can be used by the body. When the slurry passes into the intestine, it gets in contact with…
Room 337, an 85- year old widowed white female, presented six days ago to Lynchburg General Hospital with complaints of dizziness and falling. She has a past medical history of hypertension, chronic CHF, asthma and hypothyroidism. After the conduction of lab testing, Room 337 was diagnosed with syncope. Her syncope was most likely a result of insufficient O2 delivery to the brain caused by a decreased CO produced by the weakening of her heart muscle. Despite hypertension medications, Room N337’s dizziness and muscle fatigue persists demonstrated by fluctuations in her orthostatic BP readings reflecting the inability to get out of bed and move freely.…
• The stomach secretes acid and enzymes that digest food. Ridges of muscle tissue called reggae line the stomach. The stomach muscles contract periodically, churning food to enhance digestion. The pyloric sphincter is a muscular valve that opens to allow food to pass from the stomach to the small intestine. Small intestine: • The small intestine or small bowel is the part of the gastrointestinal tract between the stomach and the large intestine, and is where most of the end absorption of food takes place.…
Belinda Reyff In Defense of Food SUMMARY HEADINGS FOR THE SUPPLEMENTARY READINGS IN AGRI 180 Book title : In Defense of Food 1. List each Chapter in this book and describe in one or a couple of sentences the main ideas.…
Within the small intestine, maltose is further broken down into glucose. Within the Protein digestion pepsin which is produced by the stomach digests protein to peptides and continues in the small intestine where trypsin carries out this same process. Lipids digestion end with monoglycerides (glycerol + one fatty acid) and fatty…
The gall bladder stores bile in it and when a fatty meal is eaten, it excretes bile and the bile breaks down the fat and helps aid the digestion. The bile pigments go into the colon and give the faeces their colour and act as a deodorant. The gall bladder is an organ that is pear-shaped. It stores bile that is concentrated.…
Gluten makes these foods stick together; it gives them substance and helps them to maintain their shape (Celiac Disease Foundation). Those with Celiac disease have immune systems that create antibodies to attack this gluten protein. As a result, the intestines are inflamed and the villi that line the intestines are damaged. Villi are very important to absorption of nutrients in the digestive tract. This includes fats,…
Down from the esophagus the bolus makes its way to the stomach. In the stomach more break down takes place. Mixing in the stomach’s strong acid the churning of the food helps the further break…
Digestive Test this in n out burger consisting of cheese, meat, tomato, lettuce, onions and the magical secret sauce will first go through the mouth. When it goes through the mouth you chew it with your teeth forming a mechanical digestion. Mechanical digestion is physically breaking down the food with your tongue and teeth. Saliva has enzyme amylase which begin with the chemical digestion of starches into sugars. It also contains water, mucus and electrolytes.…
A) Explain why transport systems are required in the body? The reasons as to why transport systems are required in the body is because it allows the body to be able to respire and be able to get all that it needs to maintain the same state, for example, oxygen throughout the body as well as nutrients to the cells in the body. An example of a transport system is the Respiratory system. This system is required in the body as it helps the body to take in oxygen, this can be done through the lungs, as it allows it to be absorbed into the blood, through the use of the alveolus found within the tissue of the lungs, in order to provide energy for the cells in the body to keep functioning as well as developing.…
Food enters through the mouth, and travels via the esophagus. The food goes into the stomach where is broken down in the stomach acids, following through to the first part of the small intestine(duodenum). Then it enters the pancreas,…
It is it then carried to the stomach through the action of peristalsis (a wavelike motion) so the substance doesn’t fall too quickly. In addition the epiglottis flaps over to…
Chewing food starts the beginning stages of digestion. From here it goes into the small intestine. As the food passes through the GI tract it mixes with digestive juices causing large molecules to break down into smaller molecules. The small molecules then absorb through the walls of the small…
74-75) explained that an integral factor in enzymatic digestion is the pH of individual sections of the digestive tract. The highly acidic pH of the stomach’s gastric juice is needed to not only prevent bacterial growth, but to create an optimal environment for it’s enzymes to digest the food (now chyme) received through the cardioesophageal sphincter. The small intestine cannot handle such high pH, therefore when the stomach releases chyme into the small intestines, a signal is sent to the pancreas to release an alkaline substance called “sodium bicarbonate” to neutralize the chime’s acidic pH. Once neutralized, enzyme-rich pancreatic juices (neutral pH) work together with the enzymes of the cells found in the intestinal wall to facilitate digestion of the “three energy nutrients”. Bile (neutral pH) is secreted into the duodenum from the gallbladder (or liver-if someone is without the gallbladder) to emulsify fat for later absorption.…
QXT2- Task 6 “No man is an island no man stands alone”, no entity on Earth can survive without interacting with abiotic factors. Organisms strive daily for survival. Their survival is predicated on receiving enough energy and nutrients to carry out metabolism and maintain homeostasis. Survival of a species is determined by the fitness of an organism within its environment and how successful it is at passing its genes on to its progeny. When examining the interactions that must be carried out each day it is observed that living systems require some basic materials that are recycled again and again throughout the ecosystem.…
