The Digestive System By: Luis A. Renteria

Mouth The Mouth is an opening in your face. Like a hole.The mouth is important for breathing, eating and talking. The mouth consists of a tongue and teeth. The mouth has 12 teeth, 8 mini molars and 12 molars. 4 of your molars are your wisdom teeth which are at the back of your mouth, you usually get them in your late teens.

Esophagus The Esophagus is a muscular passage connecting the mouth to the stomach. In other words, the throat. The Esophagus is a muscular passage connecting the mouth to the stomach. In other words, the throat.

Stomach The stomach is a saclike enlargement in humans and some animals, forming an organ for storing and digesting food. The stomach is a saclike enlargement in humans and some animals, forming an organ for storing and digesting food.

Small Intestine The small intestine is a long tube (20ft to 25 ft) following the stomach and followed by the large intestine, and is where much of the digestion of food takes place.

Large Intestine The Large Intestine consists of the cecum and colon and continues after the small intestine. Its main function is to absorb water from indigestible food. Then transmits the useless waste out of the body.

Liver The liver is a dark-reddish colored organ. Its function is to regulate most chemical levels in the blood and gets rid of a product called Bile, which helps to break down fats, preparing them for further digestion.

Appendix The Vermiform Appendix is a narrow, dead-end tube about three-to-four inches long that hangs off of the Cecum (Large Intestine). There is no Known function of the appendix. Scientist think that its just part of the evolution of man. The Vermiform Appendix is a narrow, dead-end tube about three-to-four inches long that hangs off of the Cecum (Large Intestine).

Pancreas The main function of the pancreas is for it to produce a hormone called insulin. Insulin is important because it helps to regulate our blood sugar. Another function is to make enzymes like insulin for the body. These enzymes are necessary for the digestion of food. The main function of the pancreas is for it to produce a hormone called insulin.

Gall bladder The gallbladder’s function is to store the bile that is produced by the liver. A human can survive without a gallbladder.

Enzymes There are about 2,700 enzymes in the human body. Enzymes are proteins that speeds up a chemical reaction in a living organism. An enzyme acts as catalyst (A substance that speeds up a chemical reaction) for curtain chemical reactions, changing a specific set of reactants into specific products. Without enzymes life would not exist. There are about 2,700 enzymes in the human body. Enzymes are proteins that speeds up a chemical reaction in a living organism.

Bile / Bile Duct A bile duct is a small tube that transports bile. There are many ducts (small tubes) that carry the bile from the liver to the intestine. Bile is needed for food digestion.

Mucus Mucus is that green stuff inside your nose. It's also inside your throat-it's there to (hopefully) stop viruses, bacteria and anything else that may start a disease.

Chemical Digestion The Chemical Digestion is the digestion process in which enzymes are used to break foods into smaller chemical building blocks. The Chemical Digestion is the digestion process in which enzymes are used to break foods into smaller chemical building blocks.

Absorption Absorption, the absorption of substances by a tissue. As if nutrients passed through the wall of the intestine. For example if I poured water on a rag it would absorb the water; that is an example of what a tissue does to the nutrients. Absorption, the absorption of substances by a tissue.

Mechanical Digestion Mechanical digestion is the process of breaking down food in the mouth into smaller pieces that can be swallowed. Chewing is the initial mechanical breakdown of food, but the strong muscles of the stomach also break up the food.

Salivary Amylase Salivary amylase is the enzyme in the saliva. This is the enzyme that starts breaking down starches into sugars. More amylase is produced in the pancreas.

Villi Villi. Tiny, finger-like projections that enable the small intestine to absorb nutrients from food. Villi. Tiny, finger-like projections that enable the small intestine to absorb nutrients from food.

Gastric Juices A fluid secreted by glands, lining the inside of the stomach. It contains Enzymes such as Pepsin, that helps in digestion. A fluid secreted by glands, lining the inside of the stomach. It contains Enzymes such as Pepsin, that helps in digestion.

Duodenum intestine and is about 9 to 11 inches long. It Duodenum is the first part of the small intestine, which receives partially digested food from the stomach and begins the absorption of nutrients. The duodenum is the shortest part of the small intestine and is roughly horseshoe shaped, with the open end up and to the left, and it lies behind the liver. intestine and is about 9 to 11 inches long.

Chyme Chyme: the viscous, semi fluid contents of the stomach present during digestion of a meal. Chyme then passes through the pylorus into the duodenum, where further digestion occurs.
