The Digestive SystemBy: Dylan, Kohl, Raigen, Angelina, and Victoria

The Teeth

•The teeth is a mechanical digestion that breaking down the food by chewing and then it turns into food particles.

The Mouth

•The mouth opens and closes and is also a mechanical digetion.

The Tongue

•The tongue plays a role I mechanical digestion because the tongue moves the food around so it is easier.

The Salivary Glands

•The salivary glands is what makes the saliva and the saliva make your mouth not turn dry.

Epiglottis

•As you swallow, a flap of skin called the epiglottis moves across your wind pipe and food is funneled into the esophagus.

The Esophagus

•The esophagus is a tube that comes from the back of your mouth, down your throat, and all the way down to your stomach.

The Peristalsis

•The peristalsis is what squeezes the food down the throat.

Types of Digestiono There are two types of digestion- Mechanical Digestion, and Chemical

Digestion.o Mechanical Digestion happens when you chew the food and then it

breaks it down to small food particles.o Chemical Digestion breaks down large food particles into smaller

particles called Enzymes.o Enzymes are substances that bring about a specific biochemical reaction.

LARGE INTESTINE• As food reaches the large intestine, mechanical and

chemical digestion are complete.• The large intestine is about 1.5m long (in humans).• The food particles that have not been digested yet are

created into feces, which is collected in the rectum.• When the food is not digested, it turns to waste.

(POOP)

GALL BLADDER• The gall bladder produces bile.• Bile is a substance that breaks up fat particles.

How does the stomach work

•The stomach responds the stimulus in different way.

•It breaks down food using gastric juices. Gastric juices is composed mucus, hydrochloric acid, water, and digestive enzymes

•It chemically digests food into smaller particles.

•The stomach slowly releases food which is now liquid into small intestine

Stomach diseases • Gastric Cancer- Gastric Cancer is cancer that

starts in the stomach. Most common cancer is the world

• Gastritis – When the stomach lining becomes inflamed or swollen

• Gastroparesis- Where the stomach is unable to empty its contents

• Non-Ulcer Dyspepsia- Where they suffer from indigestion but no ulcer is there

• Peptic Ulcers-Break in the surface of the stomach lining deep enough to produce a crater like wall

Small intestine how does it work

•When food moves into the small intestine the chemical digestion continues. The pancreas sends digestive enzymes into the small intestine. It will complete the process of breakdown of food of starches and proteins.

Small intestine diseases

•Crohn disease- It disturbs the function of bladder/bowel movement with swelling, scars and ulcers.

•Small intestine Cancer- Its cancer on your small intestine

Liver

Liver disease's • Our liver plays a very important role in our body functions

such as protein production and blood clotting, cholesterol, glucose and iron metabolism.

• There is many other illnesses that can affect the liver.• Cirrhosis occurs when our normal liver cells are replaced by

scar tissue as a result of chronic liver disease, Cirrhosis also will block blood flow through the liver.

• The symptoms of liver disease’s are weight loss, vomiting, weakness, nausea, and yellowing skin.

• The treatment for the particular liver disease depends on the specific disease.

What does your liver do for you?• Your liver cleans your blood, by helping take

toxins/poisons out of your blood.• The liver also cleans blood that has just been

enriched with vitamins and minerals during digestion.

• After you eat, the vitamins, minerals, and other nutrients from the food pass from the intestine into the blood. Before going out to the rest of the body, the nutrient-rich blood makes a stop at the liver.

FOOD’S PATH THROUGH THE DIGESTIVE SYSTEM

The digestive system is made up of a number of organs. The beginning is at your mouth and the end is at the rectum. Any food that you take a bite of starts and ends this journey in your digestive system. You can choose any foods to eat but it is best to pick healthy, nutritious items which include a balance of proteins, starches, fats, minerals and vitamins.
