IB SEHS 2.1.1. - 2.1.2 Ventilation & Airways

Which is a principal structure of the ventilatory system?

• Capillary

• Bronchiole

• Hemoglobin

• Pulmonary artery

Which is a function of the conducting airways?

• Exchange gases

• Resist air flow

• Cool and moisten the air

• Defend from substances inhaled

Which structure is responsible for moistening air entering the ventilatory system?

• Bronchi

• Larynx

• Pharynx

• Nose

A function of the trachea is (a)   resistance pathway for airflow ✔

What are the principal structures of the ventilatory system?

• Mouth, trachea, ribs, intercostal muscles

• Nose, pharynx, aorta, diaphragm

• Nose, trachea, bronchioles, alveoli

• Mouth, larynx, diaphragm, lungs

What are the functions of the nose during inspiration?

I. To moisten the air

II. To diffuse oxygen from the air

III. To filter the air

• I and II only

• I and III only

• II and III only

• I, II and III

Which of the following is the correct order for carbon dioxide moving from the pulmonary artery to the atmosphere?

• trachea → larynx → nose

• alveoli → trachea → bronchi

• bronchi → trachea → bronchioles

• nose → trachea → bronchi
