What is the primary function of the diaphragm during ventilation?
Inhale oxygen
Exhale carbon dioxide
Aid in the expansion and contraction of the lungs
Filter impurities from the air
The role of the intercostal muscles is to support the structure of the ribcage.
Nokorɛ
Ɛnyɛ ampa
Which structure connects the trachea to the lungs?
Bronchi
Alveoli
Diaphragm
Intercostal muscles
Alveoli are adapted for gas exchange because they have:
Thick walls
A large surface area
No blood supply
A small volume
Smoking has no impact on the lungs and the circulatory system.

What is produced during aerobic respiration?
Lactic acid
Alcohol
ATP
Glucose
What is the word equation for anaerobic respiration in animals?
Glucose → Carbon dioxide + Ethanol + Energy
Glucose → Lactic acid + Energy
Oxygen + Glucose → Carbon dioxide + Water + Energy
Glucose + Oxygen → Carbon dioxide + Energy
Anaerobic respiration produces more ATP than aerobic respiration.
Nokorɛ
Ɛnyɛ ampa
What is the main difference between aerobic and anaerobic respiration?
Aerobic requires oxygen; anaerobic does not
Aerobic produces less energy; anaerobic produces more
Aerobic occurs in the mitochondria; anaerobic does not
All of the above
How does exercise affect the release of carbon dioxide during breathing?
Decreases the amount released
Increases the amount released
Has no effect
Varies based on the individual
Pleural membranes help in reducing friction between the lungs and the chest wall.
Nokorɛ
Ɛnyɛ ampa
Which of the following conditions can result from smoking?
Coronary heart disease
Improved lung capacity
Lower risk of infection
Enhanced oxygen transport
Carbon dioxide is the only waste product of aerobic respiration.
