Digestion

Digestion: From beginning to end Digestion, how you get your energy and nutrients, seems simple. However, it is actually a complex process involving three organ systems and many stages. When food is put in the mouth, the teeth grind it up into a paste and the amylase in the saliva begins to break down the carbohydrates. Swallowing takes the food into the oesophagus and by peristalsis moves it into the stomach. In the stomach, strong hydrochloric acid breaks down complex proteins over a period of

II. Anaerobic Digestion The Process of Anaerobic Digestion Anaerobic Digestion, also known as biodigestion, is a biological process that occurs when organic matter is decomposed by anaerobic microorganisms in the absence of oxygen. This means organic matter is placed in a warm airtight location and left for bacteria to digest. Anaerobic digestion occurs naturally in swamps and bogs but is not difficult to mimic at a landfill site. So long as the anaerobic plant is properly monitored, biodigestion

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

Digestion begins when one sees food. Upon seeing food the brain sends signals for the salivary glands to release saliva. When food is first placed into the mouth by taking a bite it is masticated and broken down to increase the surface area so that food can be digested faster, as well as allowing it to be swallowed. While being masticated food is moistened with saliva, which contains Amylase, which begins the process of breaking down carbohydrates. Once thoroughly chewed saliva forms the food into

1. Firstly, the cracker enters the mouth. This is where the cracker is physically broken down by chewing, and chemical digestion of carbohydrates begins. Salivary glands in the mouth produce saliva which moistens dry food and contains salivary amylase, a digestive enzyme that breaks down carbohydrates. The cracker is then swallowed. Paristalsis (involuntary muscle contractions) push food down the esophagus. In the stomach the cracker bathes it in gastric juices. Gastric juice is composed of three

Digestion is the breaking apart of foods into smaller and smaller units and absorbtion is the movements of those small units from the gut into the bloodstream or lymphatic system for circulation. (1) The digestive system is what keeps you going from day to day because without the digestive system you wouldn’t be able to consume anything. You also wouldn’t be able to absorb the necessary nutrients you need for your body to keep functioning correctly. The organs that play a role in the digestive system

swallow. Digestion of the pizza starts in the mouth with food chewing and mixing it with saliva to make food bolus. Teeth are arranged according to function starting with the incisors that cuts the food, canines that tear food, the premolars and molars that crush and grind the food. The pizza will then proceed to the mouth through the pharynx and then the esophagus; a straight, muscular tube that descends through the chest to the stomach. At the stomach, both chemical and physical digestion takes place

The mouth does both mechanical digestion and chemical digestion. Mechanically, your incisors cut food into small pieces, next your canines make the food pieces even smaller, than premolars and molars crush and grind the food, finally saliva moistens the food to a slippery mass. Saliva contains enzymes which speed the chemical reaction in the body, this part is the chemical digestion. Your mouth is the first in your digestive system. Your esophagus connects your mouth to your stomach. It is made

Task 4 – Chemical digestion The digestive system is the process that involves the mouth, esophagus, stomach, small intestine, large intestine and rectum. For the body to function, the body`s cells needs energy and that energy will come from the food we eat. All the food we eat contains nutrients, carbohydrates, glucose, lipids, protein and many more other substances. The only way the body can absorb and convert these nutrients into energy to our cells is through breaking down the large molecules

cookie into smaller pieces and remove its nutrients for use by the body. Tracing the digestion of a cookie involves a quick trip down your esophagus, a churn in the stomach and a slow, winding movement through the intestines. The Mouth The digestive process begins before the cookie even enters your mouth.Once you take a bite, your teeth initiate the mechanical digestion process.Your teeth smashes the cookie into smaller pieces and your tongue pushes
