Review of Digestive Tract

1) What is the total length of a human intestine?

2) How long does it take the average person to digest their food?

3) What do enzymes do?4) True or False: Villi have blood vessels

inside of them so they can transport nutrients from the small intestine to other parts of the body.

5) Pictured to the right is a bowl of “menudo”. Menudo is a Mexican dish. Can you guess what part of the animal they use to make menudo?

Student Questions

1) Why do I always have to go to the bathroom after I eat?When you start to eat food, your digestive system starts working, and for many people this results in having to go to the bathroom soon.

2) Why do people throw up when they touch their uvula?This is a natural reflex in our bodies. This is to stop us from choking on foods that are too large.

3) What does the pancreas do??Answer this question later today.

What are the digestive system accessory organs?

Remember, the accessory organs help, but the food does not pass through them.

Salivary glands make saliva and push it into the mouth.

Digestive System Accessory Organs: Salivary Glands

Salivary glands make saliva and push it into the mouth.

Enzymes

The liver makes bile. The liver also takes toxins out of the body, and stores sugar.

Digestive System Accessory Organs: Liver

The liver makes bile. The liver also takes toxins out of the body, and stores sugar.

Digestive System Accessory Organs: Liver

What does bile do?

The liver makes bile. The liver also takes toxins out of the body, and stores sugar.

Digestive System Accessory Organs: Liver

What does bile do?

It helps break down food in the small intestine.

Digestive System Accessory Organs: Gall Bladder

The gall bladder stores bile from the liver. The gall bladder puts bile into the small intestine to help digest food. The gall bladder is attached to the liver!

Student Question:What does the pancreas do?

Like the liver, the pancreas makes digestive juices that help break down food in the small intestine.

Digestive System Accessory Organs: Pancreas

Like the liver, the pancreas makes digestive juices that help break down food in the small intestine.

Digestive System Accessory Organs: Pancreas

What is in the digestive juices from the salivary glands, liver and pancreas that help speed up digestion?

Small Intestine

Like the liver, the pancreas makes digestive juices that help break down food in the small intestine.

Digestive System Accessory Organs: Pancreas

What is in the digestive juices from the salivary glands, liver and pancreas that help speed up digestion?

ENZYMES!Small Intestine

Don’t forget, BOTH the gall bladder and pancreas put digestive enzymes into the small intestine.
