Which of the following best describes the anatomy of the respiratory tract?

• The respiratory tract consists of only the lungs.

• The respiratory tract includes both the upper and lower sections.

• The respiratory tract is only made up of the trachea.

• The respiratory tract is unrelated to breathing.

What is one of the main functions of the respiratory system?

• To digest food

• To pump blood

• To facilitate gas exchange

• To produce hormones

How are the respiratory and cardiovascular systems related?

• They function independently of each other.

• The respiratory system supplies oxygen, which the cardiovascular system transports.

• The cardiovascular system controls breathing rate.

• The respiratory system digests nutrients for the cardiovascular system.

Which process is directly controlled by the mechanisms of ventilation?

• Blood clotting

• Movement of air in and out of the lungs

• Production of red blood cells

• Digestion of proteins

How does ventilation impact blood pH?

• It has no effect on blood pH.

• It increases blood sugar levels.

• It helps regulate blood pH by controlling carbon dioxide levels.

• It only affects oxygen levels, not pH.
