Digestive System Essay

and each system within the body follows common principles for this exchange, but adapts to suit its own requirements and function. The human body has a smaller surface area to volume ratio in comparison to smaller organisms, which are able to gain all gases that are needed though simple diffusion, and therefore is not able to complete all of the exchanges of the materials it requires in the same way. To ensure that it obtains all of the materials that are needed, specialised systems are present

because once your sense of taste starts it produces saliva. Saliva dissolves the food while the teeth chop food down to pieces before it follows through to the pharynx. That’s why the mouth starts off the digestive process. Fibers are important in your diet because it helps with your digestive system. We should consume at least 20 to 35 grams of fiber a day. Fibers are the elements in plants such as fruit, vegetable, and whole grain. Fibers help to prevent colon cancer and other serious diseases like

In this essay I will be exploring the digestive system of both a human and a wild rabbit. Digestion is the process of breaking down food so that the body can use the food’s nutrients to help the body function (Pearson Science, 2011). The wild rabbit is an herbivore during the warmer seasons its diet consists of grass, weeds, clovers, wildflowers and vegetable plants. They also try and search for fruit and crops to eat. Whereas when the weather turns cold, wild rabbits will munch on twigs, buds, bark

Firstly the food enters the digestive system via the mouth or oral cavity which is mucous membrane lined. In this process the food begins to break down due to the salvia in the mouth which contains mucus, a very effective lubricant that coats the food to help with swallowing. Before it is swallowed the food is also broken down by the teeth which are the incisors which cut food with their sharp thin edges, the canines which are responsible for holding and grasping food which have a pointed edge and

Student Discussion Assignment Trace and discuss the complete movement of a bolus of food entering and exiting the human via the digestive system. 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

1) Main components in the digestive system include the teeth, tongue, salivary glands, liver, small intestine, stomach, and pancreas..The function is to digest food. Main components of the circulatory system are the heart, blood vessels, and blood. The heart helps pump blood throughout the body, the functions are to transport oxygen as well as blood from the lungs and to other tissues in the body. Main components of the respiratory system include the nose, pharynx, larynx, trachea, and bronchi

The throat, Pharynx, is part of the digestive and respiratory system, extending from the base of the skull to the level of the lower border of the cricoid cartilage and the 6th cervical vertebra. It is a fibro-muscular tube lined with mucous membrane and is divided into three sections:- The Nasopharynx, The Oropharynx and The Laryngopharynx, with all sections acting as a common passage for both food and air.

small amount of the allergen can cause symptoms such as urticaria, angioedema, eczema, nausea, vomiting, and wheezing (Husain & Schwartz, 2013). These reactions primarily consist of the interaction between the proteins found in nuts and the digestive and immune systems (White et al., 2015). While there is extensive research taking place in the prevention and treatment of peanut and TN allergies, the only current management is the strict avoidance of nut products (Wainstein &

4. Eight pathological conditions of the digestive system. 1. Dysentery is an inflammation of the intestines that causes severe pain. The cause for dysentery are bacteria, and parasites that can occur in the food, or drinks. Besides the severe pain the patient may also experience diarrhea, and blood in the stool. To treat this infection antibiotic is needed, drinking plenty fluid (because diarrhea can cause dehydration) or patients may receive fluid through an IV. 2. Hemorrhoids are veins that are

Bodily Systems Assignment Digestive System 1. Gluten is a protein that is found present in many grains. It is made up of two proteins, gliadin and glutenin. Gliadin is the part of gluten that some people cannot tolerate. Some natural food sources that contain gluten are pasta, cous cous, bread, cookies, cakes, muffins, and crackers. Some alternative food products or grains for individuals that cannot tolerate gluten are buckwheat, corn, quinoa, and rice. 2. Some common symptoms that may indicate
