What is respiration?

• The process of exchanging gases between the atmosphere and the alveoli.

• The process of gas exchange that occurs within the body.

• The process where blood releases oxygen and binds carbon dioxide in tissue cells.

• The process of inhaling and exhaling air.

Which of the following organs are part of the upper respiratory system based on structural classification?

• Larynx and trachea

• Bronchus and bronchioles

• Nose and pharynx

• Lungs and alveoli

What is the function of the concha in the nose?

• Filtering dust particles from the air.

• Trapping foreign objects like viruses and bacteria.

• Warming and humidifying inhaled air to match body temperature.

• Connecting the pharynx to the trachea.

What is the primary function of the epiglottis?

• To filter dust and foreign particles from the air.

• To produce sound through vocal cord vibrations.

What primarily controls the pitch of a person's voice?

• The amount of air passing through the pharynx

• The tension of the vocal cords

• The size of the nasal cavity

• The thickness of the epiglottis

What is the primary function of the cilia found on the walls of the trachea?

• To produce sound waves

• To regulate air temperature

• To filter foreign objects from the respiratory tract

• To facilitate gas exchange

What is the function of the pleura, the double-layered membrane surrounding the lungs?

• To facilitate the exchange of oxygen and carbon dioxide

• To connect the trachea to the bronchi

• To protect the lungs from friction during expansion and contraction

• To produce mucus for filtering air

Why are the walls of the alveoli composed of a single layer of flat epithelial tissue?

• To provide structural support to the lungs

• To increase the overall volume of the lungs

• To facilitate the easy passage of gas molecules

• To prevent the collapse of the air sacs
