Functions of the Respiratory System

This tutorial introduces the respiratory anatomy, focusing on the system's role in oxygen delivery and carbon dioxide removal. It covers the air's journey from the nose and mouth through the nasal cavities, pharynx, larynx, and trachea, highlighting key structures like the voice box and cartilaginous rings. The tutorial emphasizes the importance of each component in air filtration, conditioning, and voice production.

What is the primary function of the respiratory system?

• To digest food

• To deliver oxygen to cells and remove carbon dioxide

• To produce hormones

• To circulate blood

How does the nose contribute to the respiratory process?

• By digesting food

• By pumping blood

• By producing sound

• By filtering, warming, and moistening the air

What is the role of the pharynx in the respiratory system?

• To pump blood

• To produce hormones

• To filter air

• To connect the nasal cavities and mouth to the esophagus and larynx

Which part of the pharynx is located just behind the mouth?

• Laryngo pharynx

• Oro pharynx

• Naso pharynx

• Trachea

What is the larynx commonly known as?

• Windpipe

• Nasal cavity

• Esophagus

• Voice box

What structure forms the Adam's Apple in males?

• Epiglottis

• Cricoid cartilage

• Thyroid cartilage

• Hyoid bone

Where is the larynx located in relation to the hyoid bone?

• Below the hyoid bone

• In front of the hyoid bone

• Behind the hyoid bone

• Above the hyoid bone

What is the primary role of the larynx in the respiratory system?

• To filter air

• To produce voice and allow air passage

• To digest food

• To circulate blood

What is the function of the trachea in the respiratory system?

• To produce sound

• To connect the larynx to the lungs

• To filter blood

• To digest food

What is the structural feature of the trachea that helps maintain its shape?

• Smooth muscle

• C-shaped cartilaginous rings

• Bone

• Fibrous tissue
