What is the function of the pharynx in the human body?

• It pumps blood throughout the body

• It is a passageway for food to the esophagus and air to the larynx

• It filters waste from the blood

• It produces digestive enzymes

Which structure is also known as the windpipe?

• Larynx

• Trachea

• Bronchi

• Diaphragm

What is the main function of the alveoli?

• Pumping blood

• Exchanging gases between air and blood

• Producing sound

• Filtering air

Which blood vessel carries blood away from the heart?

• Vein

• Artery

• Capillary

• Atrium

Which chamber of the heart receives blood returning to the heart?

• Ventricle

• Atrium

• Bronchi

• Alveoli

If a person’s diaphragm is not functioning properly, which process would be most affected?

• Breathing

• Digestion

• Circulation

• Speech

Arrange the following structures in the order that air passes through them during inhalation: trachea, bronchi, pharynx, alveoli.

• Pharynx → Trachea → Bronchi → Alveoli

• Trachea → Pharynx → Bronchi → Alveoli

• Pharynx → Bronchi → Trachea → Alveoli

• Alveoli → Bronchi → Trachea → Pharynx

Which of the following best explains the relationship between bronchi and bronchioles?

• Bronchioles are larger branches that split into bronchi

• Bronchi split into smaller bronchioles within the lungs

• Bronchioles and bronchi are the same structure

• Bronchioles carry blood, while bronchi carry air

A blockage occurs in the capillaries of the lungs. What is the most likely immediate effect on the body?

• The heart will stop beating

• Gas exchange between air and blood will be reduced

• The diaphragm will stop moving

• Food will not be digested

A patient has a damaged larynx. Which of the following symptoms would you most likely expect?
