The Digestive System

The digestive system absorbs the minerals and nutrients from the foods that have been eaten. The break down of food beings in the mouth, where the

The digestive system is a group of organs working together to convert food into energy and basic nutrients to feed the whole body. To achieve the goal of providing energy and nutrients to the body, six processes take place in the digestive system.

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,

Main components in the digestive system include the teeth, tongue, salivary glands, liver, small intestine, stomach, and pancreas..The function is to digest food.

In the digestion process, carbohydrates are digested from the mouth by the enzyme by salivary amylase, in the stomach there isn't much further break down until when it gets to the small intestines. Every sugar requires its enzyme to digest it, for example maltose requires maltase so lactose requires lactase. Lactase enzyme is naturally produced by cells in the small intestine lining; it breaks lactose into its simple sugars which are glucose and galactose. It cannot be absorbed in its complex state.

Carbohydrates are one of the main types of macronutrients that move throughout the digestive system. Starting inside of the mouth, the carbohydrate travels through the body until it gets broken down. The mouth has two forms of digestion, mechanical or chemical. Mechanical digestion includes chewing food, while chemical digestion uses saliva. The salivary glands belong to the accessory organs of the digestive tract, but play a very important role in digestion. They produce amylase, which breaks down the starch amylose and amylopectin into smaller portions. Breaking down starch, is an example of where chemical digestion occurs in the mouth.

We start with the mouth, in the feature, I am chewing on a bit of bread from a sandwich, the sandwich softens up two distinct ways, mechanical and concoction absorption. Mechanically, teeth are utilized to bite sustenance into little pieces and blend it with salivation with the tongue's assistance. The tongue then sends this pounded up sandwich down the throat to the stomach. Synthetically, Salivary organs in the mouth produce spit, containing the protein amylase to separate starch, is blended with sustenance, making it gentler and smoother prepared for its adventure down to the stomach.

Digestion starts in the mouth. Chewing mechanically breaks down the food with saliva. Saliva moistens the food and is an essential enzyme for the digestion of starch. Saliva contains ptyalin, which is capable of breaking down starch into simpler sugars such as maltose and dextrin that can be further broken down in the small intestine. About 10-15 seconds after chewing has begun, the food bolus passes through the pharynx and in the oesophagus. When you swallow, the epiglottis closes to prevent the food from entering the respiratory system. The soft palate closes to prevent food from entering the nasal cavity.

Amylase is an enzyme found in the human body. It is made in only two places, the pancreas and in the salivary glands. Amylase is an important enzyme because it breaks down starch. The enzyme works by binding with the starch substrate and breaking it down to its base component of glucose. There is a difference in the way that salivary and pancreatic amylase work. The salivary amylase breaks down the simple carbohydrates in the form of starch, starting the digestion process. Pancreatic amylase works to process the more complex carbohydrates that are in the stomach and intestines. The efficiency of the enzyme depends on environmental factors including temperature, pH level, inhibitors, activators, number of enzymes available, and number of substrates

In addition, enzymes are highly specific since they act on substrates, which bind within the active site usually through weak interactions.” (3) There are three main types of enzymes in our digestive system including amylase, protease, and lipase. In particular, these enzymes are classified based on their target substrates, and they are also produced by different parts of the digestive tract. Imagine when we take our first bite of a meal, the food then enters our mouth, which is the beginning of the digestive tract. We then chew the food to break it down into smaller pieces that are readily digested. Meanwhile, amylase, which is secreted by the mouth and found in the saliva, “begins to split long and complex starch (polysaccharide) into smaller and simple sugar such as maltose (disaccharide).” (4) Further digestion is also required to break down maltose into glucose (monosaccharide) with the help of maltase. As a consequence, “when we chew breads slowly and thoroughly, we taste sweet on our tongue because amylase in the saliva is breaking carbohydrates down into their component sugars.” (5) The equation for this process is represented as

The digestive system is very important in digesting food and breaking it down so it can be digested easily. The digestive system turns food into energy. Throughout the process there are nutrients which are absorbed. There are many things that contributed to the digestive system such as the mouth which produces saliva which helps to break down food and nutrients such as carbohydrates with the help of an enzyme called amylase. The major food groups which are called macro nutrients include carbohydrates, proteins and fats. All of these nutrients play an important role in the body. There are also many micro-nutrients which include vitamins and minerals which provide the body with health and well-being. The digestive system is made up of the mouth, which includes the teeth (the teeth are used to cut and grind food into smaller pieces, they contain blood vessels and nerves), tongue (the tongue is a muscle that has a rough surface including the taste buds), salvia glands (they produce salvia which moistens the food to make is easier to digest), the pharynx (this helps the food travel to the stomach, the pharynx also plays an important role in the respiratory system. It also contains 2 different flaps to separate the 2 functions), esophagus (this connects the pharynx to the stomach and transports chewed food to the stomach), stomach (this is a muscle that is

The process starts at the mouth where food is chewed. This causes the secretion of saliva, which moistens food to enable it to move easily through the esophagus (swallowing) and down to the stomach. There is an enzyme found in saliva that starts the process of breaking down starches from food. At this point the esophagus and brain take control as this motion becomes involuntary.

The digestive system consists of series of connected organs that together allow the body to break down and absorb food, and remove waste.

The digestive system is responsible for breaking down food and liquids into smaller simpler molecules. these molecules are soluble and are absorbed into the bloodstream of the cardiovascular system which then transports the nutrients and energy around the

The digestive system is one of the most overlooked systems in the human body. Although most people cannot sense the system at work like they do when they breathe in air or feel their heart beat, it still continues to deliver nutrients throughout the systems. The digestion system is responsible for nourishing the human body with the energy necessary to stay healthy and getting rid of the unnecessary materials (Marieb 1989).
