•
A) not the answer; the circulatory picks up nutrients from your small intestine and
carries it to your cells.
•
B) not the answer; the circulatory system picks up carbon dioxide from the cells
and drops it off in the lungs to be exhaled, and also picks up oxygen to take to the
cells.
•
C)correct answer; the digestive system and urinary systems remove solid wastes
from the body. The digestive system removes any left over food, and the urinary
system (also called excretory system-think "exit") filters out waste with your
kidneys.
•
D)not the answer; the circulatory system pumps blood throughout the body with
the heart.

on the processes of life.

Digestive Demonstration
•
Take a big bite of the cracker and chew on it for a few minutes.
•
The cracker will taste bland at first, but raise your hand when you start to taste a
sweet flavor.
•
Digestion starts in the mouth with enzymes that break down carbohydrates into
simple sugar. Does anyone know the name of this enzyme?

The Digestive System pg.?
digestive system is a group of organs that work
together to digest food so that is can be used by the body.
• The digestive system is a series of tubelike organs called
the digestive tract.
• The Digestive Tract Organs:
• Mouth, pharynx, esophagus, stomach, small intestine, large
intestine, rectum, anus
• The liver, gall bladder, pancreas, and salivary glands are also
part of this system, but food does not pass through them.
•
Digestion
• Two
types of digestion:
• The
breaking, crushing,
and mashing of food is
called mechanical
digestion.
• In
chemical digestion,
large molecules are
broken down into
nutrients.
Steps of Digestion
•
Steps of the Digestion:
•
Mouth
•
•
Teeth- chewing (mechanical digestion)
Saliva- contains an enzyme that begins chemical digestion of carbohydrates; changes complex
carbohydrates (starches) into simple sugars (glucose).
•
Esophagus- sends food to stomach
•
Stomach- breaks down food into a liquid (chyme) by the action of muscle contraction
(mechanical), enzymes, and acids (chemical).
•
Pancreas- lies behind the stomach and makes digestive enzymes and hormones that regulate
sugar levels.
•
Small Intestine- the organ between the stomach and large intestine where most of the break
down of food happens (chemical) and most of the nutrients from food are absorbed by villi.
•
Liver- Makes bile to break up fat. Stores nutrients. Breaks down toxins.
•
Gall bladder- stores bile produced by the liver
•
Large intestine- removes water from mostly digested food and turns waste into semisolid feces
(poop).
•
Rectum- stores feces until it leaves the anus.

HBS Chart- Digestion
• Function: The digestive system breaks down the
food you eat into nutrients that your body can
absorb.
• Major Organs: esophagus, stomach, intestines,
liver
• How it works with other systems: The circulatory
system absorbs nutrients from the small intestines
to carry to the body cells.
