Digestive system

Dentition (Teeth):
The type of teeth that people/animals can have are Incisors, Canines and Molars. Incisors are the teeth that you use to bite into your food. Canines are the teeth that are next in line that are developed in your mouth. You have four of them and they are your sharpest teeth and that is used to tear the food apart. Molars are used to crush the food so it is easier to swallow. 

Oesophagus:
The oesophagus is a 25 centimeter tube that transforms the eaten food (bolus) into your stomach where it is digested. 

Stomach:
The stomach is an internal organ which is connecting the Oesophagus and small intestine. It is a major part of the digestive system and it is used for digesting food. 

Small intestine:
The small intestine is used for absorption of nutrients and minerals from food takes place. It lies between the stomach and large intestine, and receives bile and pancreatic juice through the pancreatic duct to aid in digestion. 

Large intestine:
The large intestine is about 5 feet long and 3 inches in a diameter. The intestine absorbs water from waste and that is creating stool. As stool enters the rectum, nerves there create the urge to defecate. 
Liver:
The liver is an organ and it is the size of a football. It sits under your rib cage on the right side of your abdomen. The liver is essential for digesting food and ridding your body toxic substances. Liver disease can also be genetic between whanau. 

Rectum:
The rectum is a chamber that begins at the end of the large intestine, immediately following the sigmoid colon and it ends at the anus. Ordinarily, the rectum is empty because stool is stored higher in the descending colon. 

Anus:
The anus is the opening where the gastrointestinal tract ends and exits the body. The anus starts at the bottom of the rectum, the last portion of the large intestine. The anorectal line separates the anus from the rectum. Tough tissue called fascia around the anus and attaches it to nearby structures.
