IGCSE Unit 4 Lungs and respiration

What is the name of the two main branches from the trachea (one to each lung)?

• bronchi

• alveoli

• capillaries

• bronchioles

When air is pushed OUT of the lungs from an alveolus, what is the correct order for the tubes it passes through?

• bronchiole -> bronchi -> trachea -> nose

• bronchi -> bronchiole -> trachea -> nose

• trachea-> bronchi -> bronchiole-> nose

Which one of these is NOT a function of the alveoli?

• To warm air as it is breathed in

• Transfer carbon dioxide

• Perform gas exchange

• Transfer oxygen

What are the products of aerobic respiration?

• Glucose and oxygen
• Carbon dioxide and water
• Lactic acid
• Carbon monoxide

What is produced in anaerobic respiration in humans?

• Glucose and oxygen

• Carbon dioxide and water

• Lactic acid

• Carbon monoxide

During respiration, Carbon dioxide diffuses from the _______________ to the _____________.

• capillaries / alveoli
• alveoli / capillaries
• capillaries / cells

Why does your breathing rate increase during exercise?

• My breathing rate stays the same

• My lungs cannot absorb oxygen while I exercise

• The concentration of oxygen I breathe in decreases so I have to breath more

• My cells are performing more cell respiration, which requires more oxygen

The correct word equation for aerobic respiration is

• carbon dioxide + water (+ energy) → glucose + oxygen

• water + oxygen → carbon dioxide + glucose (+ energy)

• glucose + oxygen → carbon dioxide + water (+ energy)

• glucose + water → carbon dioxide + water (+ energy)

The correct word equation for Anaerobic respiration is

• glucose → lactic acid + oxygen

• glucose → lactic acid (+ energy released)

• glucose + oxygen → lactic acid (+ energy released)

• lactic acid → energy released
