Not sure what you mean by '3 types of digestion', but there are three major food groups (carbohydrates, proteins, and fats), and each has a different method of digestion by the digestive system.

What is the Digestive System?

The Digestion System is comprised of many organs in your body such as your stomach, mouth, esophagus, and your two intestines. The main functions of the digestive system is to digest the foods you eat, absorbs those nutrients from the foods you eat, and disposes of the waste product (poop). The two main types of digestion is chemical and physical digestion. Physical digestion is the physical breakdown of food, using your teeth, called mastication. Chemical digestion uses different fluids and chemicals in your body to break down the food further, such as pepsin and hydrochloric acid. At the small intestine, the food turns into chyme, which is semi-digested food, but not quiet yet waste products. The nutrients in the chyme then gets absorbed by the villi, which is the inside lining of the small intestine. The large intestine takes water out of the chyme, and turns it to fecal matter. It is then pushed to the rectum which is the last part of the large intestine, then out the anus and into your toilet. The digestive system refers to the system from the mouth to the bowels. It is the system that the body used to draw nutrients from food and to eliminate waste.

Functions of the digestion system?

Hope this helps:The digestive system includes the digestive tract and its accessory organs, which process food into molecules that can be absorbed and utilized by the cells of the body. Food is broken down, bit by bit, until the molecules are small enough to be absorbed and the waste products are eliminated. The digestive tract, also called the alimentary canal or gastrointestinal (GI) tract, consists of a long continuous tube that extends from the mouth to the anus. It includes the mouth, pharynx, esophagus, stomach, small intestine, and large intestine. The tongue and teeth are accessory structures located in the mouth. The salivary glands, liver, gallbladder, and pancreas are major accessory organs that have a role in digestion. These organs secrete fluids into the digestive tract.Food undergoes three types of processes in the body: * Digestion * Absorption * EliminationDigestion and absorption occur in the digestive tract. After the nutrients are absorbed, they are available to all cells in the body and are utilized by the body cells in metabolism. The digestive system prepares nutrients for utilization by body cells through six activities, or functions. IngestionThe first activity of the digestive system is to take in food through the mouth. This process, called ingestion, has to take place before anything else can happen. Mechanical DigestionThe large pieces of food that are ingested have to be broken into smaller particles that can be acted upon by various enzymes. This is mechanical digestion, which begins in the mouth with chewing or mastication and continues with churning and mixing actions in the stomach. Chemical DigestionThe complex molecules of carbohydrates, proteins, and fats are transformed by chemical digestion into smaller molecules that can be absorbed and utilized by the cells. Chemical digestion, through a process called hydrolysis, uses water and digestive enzymes to break down the complex molecules. Digestive enzymes speed up the hydrolysis process, which is otherwise very slow.MovementsAfter ingestion and mastication, the food particles move from the mouth into the pharynx, then into the esophagus. This movement is deglutition, or swallowing. Mixing movements occur in the stomach as a result of smooth muscle contraction. These repetitive contractions usually occur in small segments of the digestive tract and mix the food particles with enzymes and other fluids. The movements that propel the food particles through the digestive tract are called peristalsis. These are rhythmic waves of contractions that move the food particles through the various regions in which mechanical and chemical digestion takes place. AbsorptionThe simple molecules that result from chemical digestion pass through cell membranes of the lining in the small intestine into the blood or lymph capillaries. This process is called absorption. EliminationThe food molecules that cannot be digested or absorbed need to be eliminated from the body. The removal of indigestible wastes through the anus, in the form of feces, is defecation or elimination.

Are dolphins and humans digestive system similar?

Yes, since dolphins and humans are both types of mammals, the digestive systems are similar.

Why are enzyme important in digestion?

if we didn't have enzymes as part of our digestive system, digestion would take a lot longer. Enzymes break food down into smaller pieces after mechanical digestion so that chemical digestion can work on smaller pieces of food. different types of enzymes break down different types of food substances. Amylase breaks down starches into simple sugars. Protease breaks down protein and there is one that breaks down fats and oils but i cant think of its name. hope i helped :)

What organ is considered part of the digestive system because it is responsible for the breakdown of some food types?

There are two different organs which are part of the digestive system and which are responsible for breaking down some types of nutrients, these being the stomach and the small intestine. The digestive system also includes other organs but those do not break down nutrients.

What types of digestion occur in the mouth?

The body begins digestion in the mouth by breaking down food and exposing it to certain digestive enzymes. Amylase for starch digestion and lipase for fat digestion are enzymes found in human saliva. For humans, it is especially important to thoroughly chew cooked starches, such as pasta, bread, or baked potatoes, because much of our starch digestion occurs in the mouth.

What are the function of the digestive enzymes?

The human digestive system, also called 'Gastro Intestinal System' (GIT) includes everything from 'Palate' to 'Rectum'. Following are the components of this system; 1. Mouth 2. Oesophagus 3. Stomach 4. Small Intestine a. Deudenum b. Jejunum c. Ileum 5. Large Intestine a. Ascending Colon b. Transverse Colon c. Descending Colon d. Sigmoid Colon 6. Rectum Different parts of GIT secrete different types of chemicals which help in the digestion of food. These chemicals are called 'Digestive Enzymes'. They may help in digestion by breaking or diluting food particles by certain biochemical reactions.

What does the pancreas do in the digestive system?

The pancreas delivers important hormones like insulin, glucagon, and somatostatin through the body so the digestive system is able to properly digest nutrients. If the pancreas is unable to send out these hormones, the digestive system cannot digest these things and allergies to food appear like celiac and diabetes. The pancreas also produces enzymes such as amylase to perform chemical digestion. Most enzymes produced by the pancreas are also found in other parts of the body as well. The pancreas is the only exocrine gland that supplies digestive enzymes to digest all three types of foods: proteins, fats, and carbohydrates.
