Checking in

• Your excretory system diagram should now be
  labeled and colored.
• Raise your hand to get your next assignment and
  for Mrs. Fillpot to grade what you have done so
  far.

Excretory System Notes

• Tape notes into comp book
• Follow along with the presentation and fill in
  both pages of your excretory system notes.
• When you are done, you will raise your hand and
  have Mrs. Fillpot check and sign your work.

9
The Human Excretory System Notes

• The function of the excretory system is the
  excrete (get rid of) wastes that are not helpful
  to the body.

10
Waste

• Wastes that are removed include carbon dioxide,
  water, salt, urea and uric acid.
• All excreted wastes travel at some time in the
  blood.

11
Structures of the Excretory System

1. Skin
2. Lungs
3. Liver
4. Large intestine
5. Urinary System

• Think Pair Share
• Can you guess how these structures are a part of
  the excretory system?

12
Skin

• Wastes such as excess water, salt, urea and uric
  acid are removed from the body in sweat.

13
Lungs

• Excess carbon dioxide waste is removed from the
  body when we exhale.

CO2
14
Liver

• The liver is a part of what other system?
• The digestive system

Liver
15
The liver has many functions, including (but not
limited to)

• to produce substances that break down fats
• produce urea (the main substance of urine)
• make certain amino acids (the building blocks of
  proteins)
• filter harmful substances from the blood (such as
  alcohol)
• The liver is also responsible for producing
  cholesterol. It produces about 80 of the
  cholesterol in your body.

16
The Liver and Waste

• The liver produces urea and uric acid as a
  by-product of the breakdown of proteins.
• Urea and uric acid are sent to the kidneys to be
  processed.

Liver
17
Large Intestine

• The large intestine removes solid, undigested
  food from the body after it passes through the
  digestive system.
• Waste is stored in rectum until it is excreted
  from the body as solid waste.

18
The urinary system

• The kidneys filter the blood to form urine, which
  is excess water, salt, urea and uric acid.
• Read about the urinary system and fill in the
  diagram as you go. Color the organs in the
  urinary system as described in the directions.

19
Check with Mrs. Fillpot

• At this point, you should be done with all three
  of the pages Mrs. Fillpot assigned for today.
• Raise your hand and have her check and sign your
  work.
• Tape your work into your comp book.
