Essay on Digestion of Cheetos

Chyme identifies the cookie’s fat molecules, breaking them apart so they are easier for the pancreatic juice to digest. The pancreatic juice takes effect, sifting through the cookie’s nutrients and extracting the fat, protein and carbohydrate molecules. The pancreatic juice makes sure these nutrients are broken down into their simplest components. Small hair-like projections lining the walls of the intestine grab these simple molecules and push them into the bloodstream. The small amount of protein will be used to build muscles and tissues, while the carbohydrates and fats will be used to create energy. The remaining cookie components are pushed into the large

The pancreas is responsible for secreting digestive enzymes into the duodenum. These enzymes then break down protein, fats and carbohydrates. The pancreas is also responsible for making insulin and secreting it directly into the bloodstream. The livers main function within the digestive system is to process the nutrients which are absorbed from the small intestine. Bile is secreted

The common bile duct originates in the liver and the gallbladder and produces another important digestive juice called bile. The pancreatic juices and bile that are released into the duodenum, help the body to digest fats, carbohydrates, and proteins. Endocrine Function: The endocrine component of the pancreas consists of islet cells that create and release important hormones directly into the bloodstream. Two of the main pancreatic hormones are insulin, which acts to lower blood sugar, and glucagon, which acts to raise blood sugar. Maintaining proper blood sugar levels is crucial to the functioning of key organs including the brain, liver, and kidneys.

The small intestine is where the completion of the digestion and absorption of nutrients happens. The small intestine is highly adapted for the absorption; villi and microvilli. The small intestine is the main site for lipid digestion. The pancreas secretes lipases which are special enzymes that digest fats after they have been mixed with bile.

Bile is released into the gut in order to help with the digestion of foods consumed. The bile contains chemicals that break down/emulsify fats by dispersing fat globules into smaller droplets, therefore increasing the surface area of the fats. Because of an increased surface area, more reaction will be able to take place; therefore a quicker reaction will take

What enzymes act inside the small intestine and what are the functions of these enzymes?

Instead the pancreatic juice, which is the most important digestive juice, contains mainly water and enzymes such as: Amylase (breaks down carbohydrates/starch into glucose), Protease (breaks down proteins into amino acids) and Lipase which breaks down lipids (with the aid of bile) into triglycerides. It also contains sodium bicarbonate able to neutralize the hydrochloric acid present in the chyme. Through the lining of the small intestine I can also see numerous “brush border" enzymes which are further breaking down products of digestion into absorbable particles; these enzymes constitute the intestinal juice and particularly digest polysaccharides transforming them in monosaccharaides (Maltase, Sucrase and Lactase), (Patton & Thibodeau, 2008). The chyme now is entering in the jejunum (the second portion of the small intestine) where digestion continues and absorption begins. I notice that the jejunum contains numerous villi but less Brunner's glands, it also presents many large circular folds called plicae circulares (Pansky, 2007). These circular folds increase the surface area for nutrient absorption; in fact the absorption of the majority of nutrients takes place here. Now the chyme and I are entering into the ileum which is the final and longest segment of the small intestine. This tract of the

Gulp. Your favorite food, right in front of you. Mouth watering and eyes glued to the plate. A big inhale and the smell is even better than it looks. You just cannot wait to dive in and devour it, but how does one recognize what your favorite food is by just a sniff? Or what happens after you chew and swallow that meal? Mary Roach,“America’s funniest science writer”, will take you through the gates of the digestive system and explain everything one would ever want to know and more about what happens in the depths of the alimentary canal.

Explain expediency and benefits of their intake and excretionThe digestion of carbohydrate begins in the mouth, and then the salivary gland moistens the food as the food is chewed. The salivary glands have an enzyme called amylase. The amylase is a catalyst that helps in the breakdown of polysaccharides Carbohydrate food. After eating the carbohydrate food into pieces with the help of amylase, it is swallowed to the stomach (chyme) through the oesophagus, at chyme, no digestion takes place. The salivary amylase stops action, and the stomach produces acid that destroys any bacteria. From the stomach, the chyme enters the small intestine (duodenum), the pancreas releases an enzyme called pancreatic amylase that helps in the splitting of polysaccharide into disaccharide. The small intestine t produces maltase, lactase, sucrose. These are enzymes that aids in splitting the disaccharides into monosaccharides.How did the carbohydrate, fats, and proteins differ in digestion process? Explain suitability and benefits of their intake and excretion. (Atoba, MA 1988) The intestinal bacteria help in digesting carbohydrates that refused to digest like other carbohydrates or excreted with faces.Example of carbohydrate foods are bread,Paste,

Pancreatic zymogens are the inactive form of enzymes that contributes a fundamental role in the digestive process (14). The release of these enzymes are essential in the overall regulation of the acinar cells. The pancreatic acinar cells focuses on the storage and synthesis of complicated digestive enzymes. It also has the ability to regulate secretion before allowing any enzymes to reach the duodenum of the small intestine. The exocrine pancreas involves several crucial components that each carries out important responsibilities. One being the exoneration of granules from within the pancreatic duct system that eventually merges into the small intestines (15). Pancreatic zymogens are usually stimulated after reaching the duodenum. From there another form of enzyme called trypsin activates neighboring active

The Liver the largest and heaviest organ makes bile then stores it in the gallbladder. Which stores the bile then squirts it into the small intestine to break down fatty foods if needed. Banana squeezes through the Duendom the beginning part of the small intestine connecting the small intestine to the stomach. The small intestine is a 600cm long tube, and does the most absorption in the whole digestive system through little finger like sponges called villi. Villi have capillaries located through them that absorb nutrients then leak the nutrients into the bloodstream. The nutrients are leaked into the bloodstream because cells need nutrients to be able to do their jobs for the body. Nutrients and

The bile moves into the gallbladder via tiny tubes. The bile is stored in the gallbladder and waits, becoming concentrated, for the signal to be released into the duodenum aiding in digestion. Without bile, the body could not digest fats, as fats do not absorb into water. The bile acts as a detergent and allows the two to mix.

Digestion is the chemical breakdown of food into smaller components that are more easily absorbed. Digestion is a form of catabolism: a breakdown of large food molecules to smaller ones. When food enters into stomach, gastric juice starts protein digestion. Gastric juice mainly contains hydrochloric acid and pepsin. The pH value of hydrochloric in the stomach is 2, as the activity of pepsin is optimal, while it will lose its activity at pH 6.5 and above. However, pepsin will regain its activity at pH of 8. In the range of pH1 to pH6.5, pepsin will be most active at pH2, and starts to decrease its

The primary function of the digestive system is to transfer nutrients, water, and electrolytes from the food consume into the body’s internal environment. The ingested food is essential as an energy source, or fuel, from which the cells can generate ATP to carry out their particular energy-dependent activities such as contraction, transport, synthesis, secretion and even renewal of body tissues. Three primary categories of food ingested by humans which are carbohydrates, proteins and fats emerge as large molecules. These large molecules cannot cross plasma membranes intact to be absorbed from the lumen of the digestive tract into the blood or lymph; hence, it must undergo degradation in size (Sherwood, 2013).
