The two main branches from the trachea (one to each lung).
bronchi
alveoli
capillaries
bronchioles
What muscles are used in breathing in and out?
diaphragm and intercostals
diaphragm and lungs
lungs and ribs
lungs and diaphragm
What is the epiglottis?
A cartilage flap that protects the opening of the larynx during swallowing
The smaller version of a glottis
The top part of a glottis
A piece that allows vocal cords to work
What is the function of the dome-shaped diaphragm?
This is where gas exchange happens.
Air passes through the diaphragm on the way to the lungs.
It attaches to the lungs to help in breathing.
It is under the lungs and helps move air into and out of the lungs.
Name the organ labeled #6.
alveoli
bronchi
trachea
lungs
What happens during inspiration?
The diaphragm contracts and pulls down to cause air to rush into the thoracic cavity.
The diaphragm relaxes and causes a pressure change and air rushes out.
The diaphragm relaxes and causes the thoracic cavity to get smaller.

Which structure in the respiratory system is primarily responsible for filtering and humidifying the air we breathe?
Bronchi
Larynx
Nose
Trachea
What is the primary function of the cilia in the respiratory tract?
