Digestion

how it impacts on the lifestyle will be explored in this essay. Digestion is important to animals as it allows the food molecules to be broken down into smaller pieces, releasing the energy found in the bonds of the food. This energy is essential to maintain metabolism and to carry out the essential life processes. There are many important components of the digestive system. The first is the mouth, this is where mechanical digestion…

liver, gall bladder, and the pancreas 2. Which organs of the digestive system come in contact with food, and what are some of their digestive functions? Mouth is used for ingestion of food. Saliva produced by salivary glands, helps in the early digestion of carbohydrate and fat by enzymes amylase and lipase. Pharynx helps in muscular propulsion of food into the esophagus Esophagus help transport food to the stomach (peristalsis) Stomach help to chemically breakdown food via production of…

produce tannin binding proteins (Clauss, Hummel, Völlm, Lorenz, & Hofmann, 2006). Although it is typically thought that tannins only affect non-ruminants, researchers have found that tannin content in feedstuffs can have a negative effect on ruminant digestion of protein (Min, Solaiman, Terrill, Ramsay, & Mueller-Harvey, 2015). Thus it is plausible that the okapi, producing high amounts of tannin binding proteins, would be able to have the same if not higher percent CP digestibility than the…

anus. Also, digestion process start from the mouth; the ingestion of food stimulate the salivary secretion (mouth), the food is chewed before its passage through the esophagus down to the stomach where mechanical and chemical digestion takes place. Pepsinogen from the chief cells helps with the digestion of protein, amylase from the saliva and pancreatic fluid helps with the digestion of carbohydrate, and a pancreatic enzyme known as lipase helps with fat digestion, but the protein digestion…

then to the large intestine. 2. How long does the food remain in each segment of the digestive tract and what physiological processing takes place during this time? • Chemical and mechanical digestion begins in the oral cavity. Temperature, taste, texture are sensed, and the saliva helps the chemical digestion because it is secreted by the salivary glands. The breakdown of the enzymes in the saliva helps the food to be swallowed. The mechanical breakdown of the food is from the teeth, and when…

hydrochloric acid in the digestion of foods. Point out how excess acid contributes to the discomfort known as indigestion. Explain how the stomach secretes a mucous layer, which protects it from being damaged by the hydrochloric acid it produced.  Hydrochloric acid (HCl) is a clear, liquid. Which is produced in our stomach when we eat a meal. The major role that it plays in our stomach is to break down food and cause the release of enzymes that further aid in digestion. It is also used as a…

component is the mouth, where digestion starts. In the mouth the lips, tongue, taste buds, teeth and salivary glands all help to start the process of digestion. The lips help to keep food in the mouth. The tongue aids in digestion because it “guides food during mastication, forming of the bolus or small ball of food and swallowing” (Johnstone, et al, 2014). Taste buds are also important in the process of digestion, and they go hand in hand with the salivary glands to aid in digestion. The…

as you are swallowing it? Have you thought about where it goes, or what is going on inside your body as you digest? The term is called digestion. Digestion is the breakdown of food we eat, and turn the food into small, tiny, components that is absorbed through our bloodstream. When digestion your food it goes through two breakdowns; Mechanical, and Chemical digestion. But what happens once the food enters your bloodstream, and breakdown into small molecules? The term is called the digestive…

can enter the blood stream. In order for these foods to be broken down three separate digestions must take place. The three digestions are mechanical digestion, enzymatic digestion, and hydrochloric digestion. Mechanical digestion includes various functions in the oral cavity such as chewing, and also functions in various organs such as the stomach and intestines. The second type of digestion, chemical digestion, is involved in the breaking down of foods by…

with lagomorphs such as rabbits and a variety of rodents who practice caecotrophy. Caecotrophy, also known as coprophagy, is the act of eating soft excretions, known as caecotrophs, directly from the anus for additional nutritional absorption and digestion of plant fibers (Halls, 2008). Although strange, and seemingly unhygienic, to humans, rabbit owners must allow the behavior of coprophagy because it promotes proper nutrition for companion rabbits. The phenomenon of coprophagy is performed at…
