1. 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?

2. 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.

10. Salivary glands make saliva and push it into the
mouth.
Digestive System Accessory Organs:
Salivary Glands

11. Salivary glands make saliva and push it into the
mouth.

13. The liver makes bile. The liver also takes toxins out of
the body, and stores sugar.
Digestive System Accessory Organs:
Liver

14. 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?

15. 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.

16. 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!

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

19. Like the liver, the pancreas makes digestive juices that
help break down food in the small intestine.
Digestive System Accessory Organs:
Pancreas

20. 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

21. 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

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