What is the digestive system?
A system to take out the bad stuff that's in your body

A system that the organs in the stomach make food for the body to digest.
Where does the digestive system start?
The liver
The throat
The stomach
The mouth
What is the term for a group of organs that break down food so that it can be used for energy, cell growth and repair?
circulatory system
digestive system
excretory system
muscular system
nervous system
Bile is produced in the
stomach
small intestine
pancreas
liver
The main purpose of the large intestine.
absorb hormones
absorb protein
absorb nutrients
absorb water
Where does food go after it is in the small intestine?
Stomach
Colon
Mouth
Large Intestine
Bile is produced in the
stomach
small intestine
pancreas
liver
How are macromolecules in our food broken down?
They are absorbed as they are into the bloodstream
They are broken down mechanically and chemically into their simplest forms
They are broken down only chemically
They are broken down only mechanically
What does the salivary glands do for the digestive system?
It produce saliva, which keeps the mouth and other parts of the digestive system moist.
It produce moist, which keeps the mouth and other parts of the digestive system saliva.
It produces ptyalin to make saliva for the mouth, so the system can start.
What are 2 MOST important organs of the digestive system?
small intestines
esophagus
large intestines
pharynx
Which is the esophagus?
A
B
C
D
E
What does the large intestine do?
digest the food from this process
makes a pathway for the food
reabsorb a lot of the water from this process
absorbs the food from this process
What does the pharynx have that functions it to sallow the food?
salivary glands
saliva walls
esophagus
muscular walls
If you wanted to find the glands that produce salivary amylase, where would you look?
In your mouth
In your throat
In your intestines
In your stomach
What is the main function of villi?
They move food from the stomach to the small intestine
They absorb nutrients into the bloodstream
They absorb water from chyme
They move food from the small intestine to the large intestine
What might happen if your large intestine did not absorb water from chyme?
You couldn't digest food.
You wouldn't be able to go to the bathroom.
You would become dehydrated.
Solid waste would not be able to move throughout the digestive system
Why do we need food to break apart the food we eat?
So it can fit into our stomachs
So our bodies can use the nutrients from the food
So liquids can be separated from solids
So that our bodies' enzymes have something to do.
Where does digestion begin?
Our teeth
Our stomach
The esophogus
Small intestines
Chewing is an example of what type of digestion?
Dental
Fragmentary
Chemical
Mechanical
What is the role of the pancreas in the digestive system?
Produces bile to aid in digestion
Secretes enzymes to break down carbohydrates, proteins, and fats
Absorbs nutrients into the bloodstream
Stores and concentrates bile
Which part of the digestive system is primarily responsible for water absorption?
Stomach
Small intestine
Large intestine
Esophagus
What is the function of the enzyme amylase in the digestive system?
Breaks down proteins into amino acids
Breaks down fats into fatty acids and glycerol
Breaks down carbohydrates into simple sugars
Breaks down nucleic acids into nucleotides
How does the structure of the small intestine aid in its function?
Its smooth surface allows for rapid movement of food
Its villi and microvilli increase surface area for nutrient absorption
Its thick walls protect against stomach acid
Its short length speeds up digestion
