1. Respiratory and Excretory Systems

2. Vocabulary
Alveoli – Air Sacs that make up the lungs, where gas exchange occurs
Capillary – tiny blood vessels that carry materials and exchange them with the cells throughout the body
Waste – materials not needed by the body and can be toxic if not gotten rid of

3. Respiratory System:
Function: gas exchange, bring _______to the blood and remove ________________ from the blood
Organs:
1. Nose: _______, ______, and moistens air
2. Trachea: protected by ________, contains the vocal cords
Epiglottis: covers trachea when swallowing food
3. Bronchi: two branches that lead to the _______
Oxygen
Carbon Dioxide
Filters
Warms
Cartilage
Lungs

4. Respiratory System: 4. Lungs: made up of ______
where gas exchange occurs ( oxygen _______ and carbon dioxide _________ the blood)
5. Diaphragm: muscle that controls _______________
Alveoli
Enters
Leaves
Breathing

5. Diagrams:
Respiratory and Circulatory systems work together by the blood bringing carbon dioxide to the lungs to be exhaled, and the lungs taking in oxygen and giving it to the blood to be transported throughout the body.

6. Emphysema: a disease that reduces the number and elasticity of ___________
Alveoli

8. Nonsmoker Smoker

9. Excretory System: Function: remove ____________
Waste
Organs:
1. Lungs: removes ____________
2. Large Intestine: removes _______waste from the digestive system
3. Skin: removes ________ and heat
4. Liver: removes excess _________ acids and worn out _____
5. Kidneys: produce urine to remove ________, salts and nitrogen wastes
Carbon Dioxide
Solid
Water
Amino
RBC (Red Blood Cells)
Water

10. Lungs are a respiratory organ because they take in oxygen and an excretory organ because they get rid of carbon dioxide
Human Kidney

11. Diagrams: Skin Large Intestine Lungs Gets rid of Water and Heat
Gets rid of CO2 (Gas)
Gets rid of Solid Waste
Brings blood to the kidneys
Kidney
Brings filtered blood back to the heart
Filters/Cleans Blood
Liver
Transports Urine (Liquid Waste) produced by the kidneys to the bladder
Gets rid of Amino Acids and RBCs
Gets rid of Urine (Liquid Waste)
Muscular Sac that stores Urine
Urethra
Eliminates Urine from the body

12. What would happen if your excretory system didn’t work and why?
Describe the exchange that occurs with the circulatory system and the body cells.
What would happen if your excretory system didn’t work and why?
The circulatory system delivers and gives the body cells oxygen and nutrients as it takes away carbon dioxide and other wastes and delivers them to the excretory organs
Your cells would start to die because waste is toxic
