How does the respiratory system exchange gases between the lungs and the environment? 

• CO₂ is inhaled from the environment and O₂ is exhaled by the lungs
• O₂ is inhaled from the environment and CO₂ is exhaled by the lungs 
• CO₂ is inhaled from the environment and CO₂ is exhaled by the lungs 
• O₂ is inhaled from the environment and O₂ is exhaled by the lungs

All of the following are functions of the respiratory system EXCEPT

• Inhale to take in oxygen
• Exhale to release carbon dioxide
• Create sound with vocal chords
• Create blood cells

Structure where respiratory gas exchange occurs

• capillaries
• alveoli
• trachea
• bronchi

Component of blood that carries O₂ and CO₂ throughout the body

• Red Blood Cells
• Plasma
• Hemoglobin
• Platelets

Airway that connects the larynx to the bronchi

• pharynx
• nasal cavity
• secondary bronchi
• trachea

After O₂ enters the bronchi and moves through smaller and smaller branches, it moves to - 

• the alveoli
• the trachea
• the pharynx
• the larynx

When O₂ is used in cellular respiration, _________ this WASTE PRODUCT is produced.

• CO₂
• ATP
• Glucose
• More O₂

Capillaries deliver O₂ to - 

• the lungs
• the kidneys
• body cells
• the lungs

#6 is pointing to -

• the diaphragm
• the alveoli
• the bronchi
• a rib

How are the lungs excretory organs? 

• They excrete O₂ which is waste 
• They excrete CO₂ which is waste
• They excrete inorganic salts which are wastes
• They excrete urea which is waste
