Year 11 Respiratory System

Given the following structures:
1. larynx
2. nasal cavity
3. pharynx
4. trachea
Which of the following is the correct order that air would flow during inhalation. 

• 1,2,3,4
• 2,3,1,4
• 2,1,3,4
• 4,2,3,1 

The actual gas exchange with the blood occurs in the 

• bronchi
• bronchioles
• alveoli
• ventricles

The movement of oxygen from the alveoli to the blood and from the blood to the tissues is due to the process of... 

• osmosis
• diffusion
• cytokinesis
• phagocytosis

When the diaphragm contracts...

• the volume of the thoracic cavity increases and the pressure decreases, causing air to rush into the lungs.
• the volume of the thoracic cavity decreases and the pressure increases causing air to rush out of the lungs. 

When the diaphragm relaxes...

• the volume of the thoracic cavity increases and the pressure decreases, causing air to rush into the lungs.
• the volume of the thoracic cavity decreases and the pressure increases causing air to rush out of the lungs. 

Gases move from a lower pressure to a higher pressure. 

• True
• False

What does the Larynx hold ?

• The larynx holds the whole respitory system. 
• The larynx holds the trachea. 
• The larynx holds the vocal chords. 
• The larynx hold the wind pipe. 

A chamber behind the nose and mouth that leads to the trachea

• pharynx
• trachea
• epiglottis
• larynx

Letter B is pointing to which organ of the Respiratory System?

• Nose
• Trachea
• Lungs
• Diaphragm

During exhalation the diaphragm moves up and the volume of air decreases in the lungs.

• True
• False
