the functional respiratory units where gas exchange occurs are the (a)  

The two branches at the end of the trachea are called _________

• bronchus

• bronchioles

• bronchi

• alveoli

The ________ keeps the windpipe open and is lined with fine hair called _______

• trachea

• bronchus

• villi

• cilia

provides and alterantive air passage

• nose

• pharynx

• mouth

• larynx

passage way for air; leads to the trachea

• larynx

• pharynx

• nose

• bronchus

which of the following is the correct formula for respiration in yeasts

• C₆H₁₂O₆ + 6 O₂ → 6 CO₂ + 6 H₂O + Energy

• C₆H₁₂O₆ → 2 C₃H₆O₃ (lactate) + Energy

• C₆H₁₂O₆ → 2 C₂H₅OH (ethanol) + 2 CO₂ + Energy

• 6 CO₂ + 6 H₂O + Energy → C^₆H₁₂O₆ + 6 O₂

Which sequence represents the correct flow of air from the nose to the alveoli in the respiratory system?

• Nose - Pharynx - Larynx - Trachea - Bronchi - Bronchioles - Alveoli

• Nose - Pharynx - Larynx - Trachea - Bronchioles - Bronchi - Alveoli

• Nose - Larynx - Pharynx - Trachea - Bronchi - Bronchioles - Alveoli

• Nose - Pharynx - Larynx - Bronchi - Trachea - Bronchioles - Alveoli

True or False: The exchange of gases in the alveoli is an entirely passive process, with no need for energy expenditure by the body.
