Flashcards

Respiration

The process of releasing energy from food, involving the intake of oxygen and the release of carbon dioxide and water.

Gas exchange

The process of transferring oxygen from the lungs to the blood and transferring carbon dioxide from the blood to the lungs.

Cellular respiration

The process by which cells use oxygen to break down glucose (sugar) and produce energy, carbon dioxide, and water.

Aerobic respiration

A type of respiration that requires oxygen to produce energy.

What is the function of the epiglottis?

The epiglottis is a flap that prevents food from entering the trachea (windpipe) during swallowing, directing it towards the esophagus.

What is the function of the capillaries in the respiratory system?

Capillaries are tiny blood vessels surrounding the alveoli, allowing oxygen to move from the air into the bloodstream and carbon dioxide to move from the blood into the air.

What happens to oxygen during respiration?

Oxygen enters the alveoli in the lungs and then diffuses into the blood.

What happens to carbon dioxide during respiration?

Carbon dioxide moves from the blood into the alveoli and is exhaled.
