Essay on Purpose of the Digestive System

Cows who are on grass tend to not produce nearly as much but it is proven that the less milk a cow produces, the more vitamins in her milk. This is because a cow has a set amount of vitamins to transfer to her milk, and if she’s bred, fed, and injected to be a Super Producer, her milk has fewer vitamins per glass. It is a watered down version of the real thing. (Super Natural 1)

The digestive system of a pig is classified as monogastric or non-ruminant, which is having a stomach with only a single compartment, like humans. In addition, the digestive tract of the pig has five main parts, including the mouth, esophagus, stomach, and small and large intestines. Furthermore, the mechanical breakdown of the food begins upon the entrance of the mouth in the digestive tract. Basically, the food is grinded into smaller pieces by its teeth. Next, saliva is produced in the mouth, acting to moisten the small food particles, along with an enzyme that starts the digestion of the starch. Then, the food is pushed towards the esophagus with the help of the tongue. Primarily, the esophagus carries the food from the mouth to the stomach, being a tube, which is carried out with the help of a series of muscle contractions that push the food towards the stomach. Subsequently, after the first of the contractions, swallowing, has taken place, the cardiac valve, located at the end of the esophagus, prevents food from passing from the stomach back to the esophagus. Likewise, the stomach comes next in the digestive tract; it serves as a reaction chamber, adding chemicals to the food. Also, hydrochloric acid and enzymes help break down food into small particles of carbohydrates, protein, and fats. Additionally, some particles are absorbed into the bloodstream, from the stomach, while others cannot be absorbed by the stomach, being passed to the small intestine through the pyloric valve. Moreover, the small intestine aids

Digestion is a process in which insoluble food is broken down into particles which are made into soluble particles enough to be absorbed and to be used by the body and into the bloodstream. These soluble particles are major macronutrients made up of protein, carbohydrates and fats which are needed for essential maintenance for the functioning of the human body. Nutrients are found in foods- proteins are found in red meat/poultry; sources of carbohydrates include

What are the three sections of the large intestine and what roles does each play in digestion or absorption?

The process of digestion first begins in the mouth by in taking food (bolus). The teeth help with masticating (chewing and breaking food particles down) allowing for swallowing and increasing surface area for chemical digestion. Enzymes found in saliva also facilitates with the chemical break down of food primarily starches and fats. The food swallowed then enters into the esophagus (a tube connecting the mouth and stomach). Peristalsis helps the esophagus to push the food in the direction of the stomach. The stomach contents are highly acidic (doesn’t affect the stomach mucosa since cells secrete mucus allowing the stomach wall to be protected) with pH levels between 1.5-2.5 allowing microorganisms to be killed, breaking down of food, and activating digestive enzymes producing a thick substance known as chyme. However, breaking down of foods further occurs in the small intestine consisting of: bile created from the liver, enzymes formed from the small intestine, and the pancreas facilitate with further digestion as well as HCI denatures (unfolds proteins) allowing them to be available to attack by digestive enzymes (also responsible in breaking down the protein). The pyloric sphincter separates the stomach from the small intestine allowing the chime to drop into the small intestine. The small intestine is the primary site for

The digestive system are organs converting food into energy and basic nutrients to feed the entire body.

The digestive system of the horse consists of a simple stomach, small intestines, cecum, large and small colons, rectum and anus. The horse 's stomach is comparatively small for its size. The stomach of an average horse has a holding capacity of about two gallons. This may be the reason horses eat small but frequent meals. From the stomach food moves to the small intestine, which is the main site of digestion. The small intestine empties into the cecum. The cecum; along with the large colon; make up the large intestine. Digestion in the large intestine occurs by action of bacteria and protozoa. (arg.gov.sk.ca)

The stomach is a sac-like organ with strong muscular walls that lies in the upper abdominal cavity just under the diaphragm. The stomach looks small after it is emptied, but it expands

The digestive systems of whales consist of an esophagus, a compartmentalized stomach and an intestine. They swallow their prey rather than chew it. The prey is passes into the esophagus, where it is pushed toward the expandable stomach. The food then reaches the rumen, the first stomach compartment. Pre-digested food is stored in the rumen. In this compartment the food is break down by peristalsis which is the mechanical muscular movements. Then food is directed toward the cardiac stomach, where hydrochloric acid and pepsin is produced by glands to digest the food. The food then enters the last stomach compartment, the pylorus. The latter is characterized by the presence of numerous mucous glands that facilitate

All cells need nutrient and energy to live and this energy provided by processes that called digestion. For example, when we eat some things like bread, meat, and vegetable, although they are delicious, but they are not forms of nourishment for the cells, therefore they need to change into an acceptable form such as smaller molecules to absorb by blood and carry to body cells. Digestion is break downing of food into appropriate form to absorb into the bloodstream. Digestion system contains the digestive tract called alimentary canal and associated glands that secrete digestive juices for digestion of food. The digestion or breakdown is started when food is taken in the mouth and mastication performed by the teeth and exposed to certain enzymes. The primary function of teeth is grasped and holds the food in the mouth cavity, they also modified to serve as a grinding mill for chewing food that mentions to mechanical digestion. With the help of the teeth, tongue, and jaw movement, food are chewed and mixed with saliva that secreted in the mouth and allowing chemical digestion to happen. The digestion of a ham, cheese, and lettuce sandwich begins in the mouth. The food in the mouth active the endocrine glands to secretion digestive enzyme that called salivary amylase. It helps to break down carbohydrates and starch. Thus, at this stage, the bread of ham and cheese sandwich chemically digested. Amylase is a starch digesting enzyme which breakdowns bread (starch) into maltose that

The stomach is an expandable muscular sac that is capable of holding 2-4 liters of food and liquids and breaks them down with the use of pepsinogen, an inactive form pepsin, a protein-digesting enzyme. If the stomach was damaged or dysfunctional, then it would be harder to gradually release food into the small intestine at a rate suitable for proper digestion and absorption and to digest the food because it is not as small or digested because the stomach also assists in the mechanical and chemical breakdown of the food as well as the killing of harmful bacteria due to the high acidic environment due to the hydrochloric acid.

The co-evolutionary relationship between cows and grass helps us to understand modern meat in a way that the cow can prevent trees and shrubs from gaining a foothold in their habitat, spreading grass seeds and fertilising it with his manure, while the grasses provide ruminants a supply of lunch since the fact that the cows can convert grass into high-quality protein by using the rumen.

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

Despite the species or facet of the industry an operation is built to cater too, one of the easiest ways to improve the efficiency of livestock is through feed and nutrient management. Feed efficiency for livestock only becomes more important as farmers are responsible for feeding a growing population. However, in order to do that is important that a manager or owner understands the digestive system of that species and factors that can aid in this system ability to absorb the maximum amount of nutrients. This paper will be focused around different aspects of the ruminant digestive tract, and more specifically two of the smaller ruminant species being sheep and goats. I will explain in detail the 6 essential nutrients and why they are crucial to have in a feed ration, what occurs in each compartment of the stomach, including breakdown of feed, nutrient absorption, and also parasites that can become an issue in
