Respiratory System Anatomy

What is the role of the nasal cavity in the respiratory system?

• To produce sound

• To exchange gases

• To warm, moisten, and filter air

• To transport air to the lungs

Which part of the respiratory system is also part of the digestive system?

• Larynx

• Pharynx

• Trachea

• Bronchi

What is the correct pathway of air entering the body through the respiratory system?

• Nasal cavity → Larynx → Trachea → Bronchi → Alveoli

• Nasal cavity → Pharynx → Larynx → Trachea → Bronchi → Alveoli

• Nasal cavity → Trachea → Larynx → Bronchi → Alveoli

• Nasal cavity → Pharynx → Trachea → Larynx → Bronchi → Alveoli

What is the term for the tiny air sacs in the lungs where gas exchange occurs?

• Bronchioles

• Alveoli

• Capillaries

• Ventricles

What is the significance of the pleural membrane in the respiratory system?

• It facilitates the opening and closing of the vocal cords.

• It allows for the expansion and contraction of the lungs.

• It separates the heart from the lungs.

• It filters air entering the alveoli.
