Respiratory Anatomy

This is the airway that has two pairs of vocal chords attached to it

• Lungs
• Diaphragm
• Pharynx
• Larynx

Made by the type II cells, this oily substance helps break the surface tension of moisture in the lungs, keeping the alveolar walls from sticking.

• Surfactant

• Mucus

• Goblet cells

• Niacinamide

The main function of the squamous epithelial cells in the alveolar walls is

• to create surfactant

• stimulate the diaphragm

• reduce surface tension

• gas exchange

The trachae is superior to the lungs

• true

• false

Responsible for sweeping mucus up out of the lungs.

• alveoli

• cilia

• dermacytes

• erythrocytes

Muscular structure that helps to expand and contract the lungs, forcing air in and out

• Pharynx
• Nasal cavity
• Alveoli
• Diaphragm

The anatomical name for the windpipe is the

• glottis

• epiglottis

• trachea

• vocal cords

Where does external respiration occur

• between blood and tissues

• between alveoli and lungs

• between blood and lungs

• between tissues and cells

This is a tube-like pasage used for food, liquid, and air

• Larynx
• Trachea
• Pharynx
• Lungs
