traps foreign particles and pathogens that enter the lungs

7.
Which of the following is not a characteristic of human lungs?

Both right and left lungs are composed of three lobes. 
b)
Bronchi divide to form bronchioles.
c)
Capillary supply is abundant to facilitate gas exchange with the blood.
d)
The alveoli are tiny air sacs arranged in clusters.

a)
swallowing
b)
breathing
c)
diffusion

speech
9.

We need to eat and breathe because the release of energy in cells (for repair, mitosis and maintenance) requires...

10.
The energy used to make ATP comes from...
a)
oxygen
b)
carbon dioxide

a)
True
b)
False
14.

When the diaphragm contracts during inspiration, the volume of the thoracic cavity increases and...

a)

the pressure decreases, causing air to rush into the lungs.

b)

the pressure increases causing air to rush out of the lungs.

15.

When the diaphragm relaxes during expiration, the volume of the thoracic cavity decreases

a)

... and the pressure also decreases, causing air to rush into the lungs.

False
18.

According to Boyle's Law, volume and pressure are

proportionately related: when volume increases, pressure increases

b)

inversely related: when volume increases, pressure decreases
