Digestive System

By:

Alexandra Pidcock, Viola Eromina, Sagar Modi, and Summer Emmons


Teeth

Teeth

  • They are gears to demolish chunks of food by a series of actions such as clamping, slashing, piercing, grinding, and crushing.

  • They are the first in the digestive system.

  • It is connected to the gums of the mouth and the tongue helps it chew the food.


Tongue

Tongue

  • Consists of four types of taste buds- salty, sweet, sour, and bitter.

  • It helps to remove and dislocate food particles in the teeth and shifts food around in the mouth in order to assist with the act of swallowing.

  • It is located in the mouth of the human body.

  • The food then goes to the pharynx.


Salivary glands

Salivary Glands

  • secretes into the mouth.

  • Saliva contains enzymes that help begin the process of breaking down food into smaller components.

  • It is inside the mouth.


Pharynx

Pharynx

  • Known as the throat, it is the portion of the digestive tract that receives the food from the mouth.

  • Swallowing takes place in the pharynx partly. The tongue and soft palate push food into the pharynx, which closes off the trachea.

  • The food then enters the esophagus.


Esophagus

Esophagus

  • Swallowing starts voluntarily, but becomes involuntarily afterward, because of peristalsis.

  • Peristalsis is the rhythmic waves of contraction created by the muscles of the esophagus and stomach.

  • The esophagus is linked to the stomach.


Stomach

Stomach

  • Located in the upper abdominal tract and can hold up to 2 liters of food.

  • The stomach secretes gastric juices that digest food.

  • Those juices are acids that contain numerous enzymes.

  • The stomach is linked to the small intestine


Small intestine

Small Intestine

  • The small intestine is the longest portion of the digestive tract.

  • It is more than 6 meters long and is located within the middle of the abdomen.

  • It is where the vast majority of digestion and absorption of food takes place.

  • It is between the stomach and the large intestine.


Gall bladder

Gall Bladder

  • Produces bile to break down food

  • It is linked to the liver by the hepatic duct.


Liver

Liver

  • It releases and produces bile that is stored in the gallbladder to the small intestine.

  • This bile helps break the large lipid molecules into smaller pieces.

  • It is before the stomach and under the esophagus.


Pancreas

Pancreas

  • The pancreas releases juices that help break wastes in the small intestine.

  • These juices include tryplase, amylase, and lipase that digest lipids, fats, and carbohydrates.

  • The pancreas is linked the stomach.


Large intestine

Large Intestine

  • Recovers water that has entered the canal.

  • It creates and stores wastes until it is time to eliminate it.

  • It comes after the small intestine, taking the remainder of the food.

  • It is linked to the anus.


Digestive system

Anus

  • The anus is the opening at the opposite end of the digestive route from the mouth.

  • Its job is to allow the unneeded wastes to exit the body.

  • The large intestine is the only organ that connects to the anus, which comes before it.
