Respiratory and Excretory Systems
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
Respiratory System: Function: gas exchange, bring _______to
the blood and remove ________________ from the blood
Organs:1. Nose: _______, ______, and moistens air2. Trachea: protected by ________, contains
the vocal cords Epiglottis: covers trachea when
swallowing food3. Bronchi: two branches that lead to the
_______
Oxygen
Carbon Dioxide
Filters Warms
Cartilage
Lungs
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
Diagrams: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.
Emphysema: a disease that reduces the number and elasticity of ___________Alveoli
Excretory System:Function: remove ____________
Organs:1. Lungs: removes ____________ 2. Large Intestine: removes
_______waste from the digestive system
3. Skin: removes ________ and heat4. Liver: removes excess _________
acids and worn out _____5. Kidneys: produce urine to remove
________, salts and nitrogen wastes
Waste
Carbon Dioxide

RBC (Red Blood Cells)

Lungs are a respiratory organ because they take in oxygen and an excretory organ because they get rid of carbon dioxide
• Human Kidney
Diagrams:
LungsLarge Intestine
Skin
Liver
Kidney
Gets rid of CO2 (Gas) Gets rid of Solid Waste
Gets rid of Water and Heat
Gets rid of Amino Acids and RBCs
Gets rid of Urine (Liquid Waste)
Brings blood to the kidneys
Filters/Cleans Blood
Muscular Sac that stores Urine
Brings filtered blood back to the heart
Transports Urine (Liquid Waste) produced by the kidneys to the bladderUrethra
Eliminates Urine from the body
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
Review - Electricity
• Electricity is due to moving charges
• Like charges repel (two positives or two negatives)
• Opposite charges attract (Positive and negative)
• Electricity can travel through conductors (metals)
• Electricity can not travel through insulators (plastic, rubber, glass)
