Topic:
Respiration and Air Pollution
By the end of this worksheet, you will be able to:





Identify the parts and function of the respiratory system,
Discuss different diseases of the respiratory system,
Identify different factors that can affect breathing rate.
Differentiate between aerobic and anaerobic respiration and
Show how pollutants affect the human body.
Key Points:
 The respiratory system is linked to the circulatory system.
 There are two parts of the respiratory system: the upper and lower
respiratory system.
 Air pollution and cigarette smoking both have negative effects on the human
body.
Resources:
 Respiratory System – Parts 1 and 2 on the Google Classroom page.
