Objective
Achievers on the ROAD to College will
discuss the functions and organs of the
digestive and excretory systems.
Let’s start our notes.

Digestive + Excretory Systems
We have 5 KP’s today.
The
BIG Ideas:
THE digestive SYSTEM!
1. The digestive system breaks down
ingested food into particles small
enough to be absorbed into the blood.
2. Metabolism (the breakdown of food)
produces cellular energy and accounts
for all cellular activities.

KP0: The main function of the
digestive system is to
break down food. Its main
organs include the stomach,
small intestine,
and large intestine
• KP1: When food leaves the stomach it enters
the small intestines to finish chemical
digestion.
– The small intestines are lined with villi, finger-like
projections that absorb all the nutrients into the
blood stream.
• KP2: All left-overs after the small intestine
travel to the large intestine. The large
intestine:
A. Absorbs extra water from the leftovers
B. Gets rid of the solid waste
Today’s Main Take Away!
The intestines are the
major location of
nutrient and water
recovery for the digestive
system.
• KP3: Food does not pass through the liver,
gall bladder, or pancreas but they are
important in digestion because they make
chemicals that help the other organs.
• Digestive System VIDEO!
• Shhhh…
• KP4: The main function of the
excretory system is to excrete (or
remove) toxic wastes from the body.
• These wastes are chemicals that are toxic and
that, if left alone, would seriously hurt or even
kill you (e.g., urea)
• KP5: The main organs of the excretory system
are the kidneys and bladder

What does the large intestine do?
A. Absorbs extra water from the leftovers
B. Gets rid of the solid waste
Road Check
What does the small intestine do?
Chemical digestion! It uses chemicals to further
break down food
Road Check
What does the excretory system do?
Gets rid of bodily wastes
Road Check
What are the two main organs of the
excretory system?
The kidney and bladder
