22
Q

A cavity within a bone or other tissue, especially one in the bones of the face or skull connecting with the nasal cavities…?

A

windpipe, filters the air we breathe

23
Q

Inside each of your lungs there are tubes called bronchi. These branch into even smaller tubes much like the branches of a tree. What are at the ends of these tubes?

A

alveoli

24
Q

What is the dome-shaped layer of muscle that separates the region of the lungs?

A

The diaphragm

25
Q

Where are lungs suspended in?

A

thoracic cavity

26
Q

The intercostal muscles contract, lifting the rib cage up and out. What process is happening here?

A

Inhalation

27
Q

The intercostal muscles relax, allowing the rib cage to return to its normal position. What process is happening here?

A

Exhalation

28
Q

What is the Vital capacity?

A

it’s the total volume of gas that can be moved into or out of the lungs. It can be calculated as tidal volume + inspiratory reserve ; volume + expiratory reserve volume.

29
Q

What is the Residual volume?

A

the amount of gas that remains in the lungs and the

passageways of the respiratory system even after a full exhalation.

30
Q

What is the Inspiratory reserve volume?

A

the additional volume of air that can be taken into the lungs, beyond a regular, or tidal, inhalation.

31
Q

what is the Expiratory reserve volume?

A

the additional volume of air that can be forced out of the lungs, beyond a regular, or tidal, inhalation.

32
Q

What does the lower respiratory tract contain?

A

the bronchi, bronchioles, and alveoli that make up the lungs.

33
Q

What does the upper respiratory tract contain?

A

the nasal passages, pharynx, glottis, epiglottis, larynx, and trachea.

34
Q

Each bronchiole ends in a cluster of tiny sacs called….?

A

alveoli

35
Q

Each lung is surrounded by a thin, double-layered membrane is called the?

A

(pleural membrane) — the outer layer of this membrane attaches to the inside of the chest wall.

36
Q

Another word for Windpipe?

A

trachea

37
Q

What does a spirograph represent?

A

the amount of air that moves into and out of the lungs with each breath.
