Respiratory System

Clusters of tiny air sacs that allow the exchange of oxygen and carbon dioxide

• Pharynx
• Diaphragm
• Alveoli
• Lungs

When bronchial tubes are irritated and swell (causing excessive coughing)

• Bronchitis
• Lung cancer
• Asthma
• Emphysema

When alveoli in the lungs enlarge to compensate for damaged alveoli and cant push oxygen to the blood

• Bronchitis

• Lung cancer

• Asthma

• Emphysema

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

• Pharynx
• Nasal cavity
• Alveoli
• Diaphragm

The passageway which moistens the air and has hairs that trap dust and particles

• Nasal cavity

• Bronchi

• Oral cavity

• Larynx

What is the function of the respiratory system?

• Take in O2 only

• Remove CO2 only

• Take in O2 and remove CO2

• Take in CO2 and remove O2

Made up of spongy, elastic tissue that stretches as you breathe

• Alveoli
• Lungs
• Nasal Cavity
• Pharynx

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

• Lungs
• Diaphragm
• Pharynx
• Larynx

Alveoli increase the surface area in the lungs to allow...

• More nutrients to be absorbed
• You to breathe faster
• You to breathe slower
• More O2 and CO2 to exchange

Membrane layer which covers the lungs

• Visceral pleura
• Alveolar Ducts
• Alveoli
• Bronchi
