Digestive System By: Alexandra Pidcock, Viola Eromina, Sagar Modi, and Summer Emmons
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 • 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 • 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 • 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 • 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 • 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 • 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 • Produces bile to break down food • It is linked to the liver by the hepatic duct.
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 • 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 • 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.
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.
