Respiratory System

The pathway of air into and out of the lungs is described as:

• Nasal cavity, pharynx, larynx, trachea, bronchi, bronchioles, alveoli

• Mouth, esophagus, stomach, small intestine, large intestine

• Nasal cavity, trachea, esophagus, stomach, alveoli

• Mouth, larynx, trachea, bronchi, alveoli

Link the types of cells and tissues found in each part of the respiratory passage to the function it carries out, including cartilage, ciliated epithelium, and mucous membranes.

• Cartilage provides structural support, ciliated epithelium helps in moving mucus, and mucous membranes trap dust and pathogens.

• Ciliated epithelium provides structural support, cartilage helps in moving mucus, and mucous membranes trap dust and pathogens.

• Mucous membranes provide structural support, cartilage helps in moving mucus, and ciliated epithelium traps dust and pathogens.

• Cartilage traps dust and pathogens, mucous membranes provide structural support, and ciliated epithelium helps in moving mucus.

The ATP yield of aerobic respiration is ____.

• 36-38 ATP

• 2 ATP

• 4 ATP

• 30 ATP

The function of the nasal cavity in the respiratory system is to:

• filter and humidify the air

• exchange oxygen and carbon dioxide

• pump blood throughout the body

• digest food

• pharynx

What does the nasal cavity contain?

• Cartilage and ligaments.

Fill in the blank: The pharynx serves as a passageway for air and food/drinks. Air passes to the trachea, while food/fluids pass into the ________.

• esophagus

• stomach

• lungs

• intestine

What are the components of the larynx/voice box structure?
