Respiratory System Illustrated

Which respiratory structure is supported by rings of cartilage?

• trachea

• alveolus

• bronchiole

• pharynx

Which sequence correctly indicates the branching pattern of the human respiratory system?

• trachea -> bronchi -> bronchioles -> alveoli

• trachea -> bronchioles -> bronchi -> alveoli

• alveoli -> trachea -> bronchioles -> bronchi

• alveoli -> bronchioles -> trachea -> bronchi

Which statement best describes the function of the respiratory passageways of a human?

• They permit digestive end-products to make contact with body cells.

• They permit exchange between the external atmosphere and the circulatory system.

• They transport gaseous cellular wastes from body cells to the lungs for excretion.

• They regulate the amount of ammonia and salt dissolved in body fluids.

Which part of the human respiratory system is a thin, moist membranous structure where gas exchange occurs?

• trachea

• bronchus

• epiglottis

• alveolus

Which part of the human respiratory system is correctly paired with a description of its structure?

• alveolus – microscopic sac containing rings of cartilage and ciliated membranes

• pharynx – cavity lined with flagellated mucous membranes

• bronchiole – small branching tubule lacking cartilaginous rings

• trachea – thin, moist membrane surrounded by capillaries

In the human respiratory system, bronchioles directly connect the

• trachea and pharynx

• bronchi and alveoli

• nasal cavity and trachea

• epiglottis and larynx
