The Digestive System Of The Human Body

Digestive system: the system by which ingested food is acted upon by physical and chemical means to provide the body with absorbable nutrients and to excrete waste products;

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 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 Gastrointestinal system is how our body processes energy. The system starts in the mouth where food is broken down. Next, the stomach breaks down the food for digestion. Energy is absorbed in the intestines and waste is removed and excreted from the body. This system is important because it is vital to our survival; without energy we would die.

he digestive system is a physiological marvel, composed of finely orchestrated chemical and physical activities. The food we ingest must be broken down to its molecular form for us to get the nutrients we need, and digestion involves a complex sequence of mechanical and chemical processes designed to achieve this goal as efficiently as possible. As food passes through the gastrointestinal tract, it is progressively broken down by the mechanical action of smooth muscle and the chemical action of enzymes until most nutrients have been extracted and absorbed into the blood.

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

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.

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

Your digestive system is amazing—it is comprised of a complex network of organs that work together to provide you with the nutrients from the food you eat, while eliminating harmful substances from your body. Unfortunately, the importance of digestive health is greatly underappreciated.

The digestive system is also known as the alimentary canal and is a vast system that is approximately ten meters long. The process of digestion can simply be described as the breaking down of large organic molecules obtained from foods such as carbohydrates, fats and proteins into smaller

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 digestive and excretory systems help the body with the wonderful task of food. The digestive system is composed of the stomach, mouth, liver, pancreas, and the large and small intestine. It digests food and provides the

The large,Hollow organs of the GI tract contain a layer of muscle that enables their walls to move. The movement of organ walls-called peristalsis-propels food an liquid through the GI tract and mixes the contents within each organ group. When a person swallows,Food is pushed into the esophagus,The muscular tube that cares food an liquids from the mouth to the stomach. The stomach then stores swallowed food or liquid,Mixes the food and liquid with digestive juice it produces,An then slowly empties it's contents,Called Chyme,Into the small intestine. The large intestine then absorbs water and any remaining nutrients an changes the waste from liquid to stool which is then pushed out through the

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 a group of organs working together to convert food into energy. The food digested is also tied into basic nutrients to feed the body. The digestive system is something called the tube within a tube. This is because it is a hollow structure with two openings that run the height of your body. The digestive tract consists of two parts the gastrointestinal tract known as GI tract and a set of accessory organs. GI tract starting at the oral cavity, through abdominal cavity and end at the anus. Major accessory organs include pancreas, liver, and gallbladder. There are 5 basic processes the digestive system have. The processes include and ingestion, mixing digestion, absorption, and defecation. Ingestion is the first step which is when the food and liquids are taken in the mouth and eaten. Mixing is when the smooth muscles in the walls of the GI tract mixes the food and send it through the tract. Next is digestion where the food is broken down by mechanical and chemical processes. Absorption is the epithelial
