Respiratory System

Does two very important things:

​

• brings oxygen into our bodies, which our cells need to function properly

• helps us get rid of carbon dioxide, which is a waste product of cellular respiration

​

Structures of the human respiratory system

• Trachea- (windpipe)

  • tube made of cartilage, lined with mucus & cilia (hairs).

  • Covered by epiglottis when not breathing.

  • connects  to the bronchi 

• Bronchi- 2 tubes lead to each lung

• Bronchioles small branches leading to alveoli

• Alveolus

Multiple Choice

Flap of tissue that covers the opening to the windpipe during swallowing

• Pharynx

• Trachea

• Epiglottis

Gas Exchange

• Alveoli

  • where gas exchange occurs (think of exchange like 'swapping')

Gas Exchange

Multiple Choice

What are the names of the air sacs in the lungs where gas exchange takes place?

• Alveoli

• Bronchi

• Bronchioles

• Intercostal muscles

Multiple Choice

The diagram below represents a demonstration of the breathing process in humans. The balloons represent lungs.

The change in the balloons is brought about by

• a change in air composition outside the bell jar

• a change in air pressure inside the bell jar

• an expansion of the balloons, which pulls the rubber sheet into the bell jar

• a contraction of the balloons, which forces air into the bell jar
