Mission 5 The Respiratory system study guide

Front

What is the primary function of red blood cells in the respiratory system?

Back

To carry oxygen and carbon dioxide

Front

How is oxygen transported in the blood?

Back

Primarily bound to hemoglobin

Front

How is carbon dioxide primarily transported in the blood?

Back

As bicarbonate ions

Front

What is the primary regulator of respiration?

Back

Blood carbon dioxide levels

Front

An increase in blood carbon dioxide levels leads to:

Back

An increase in breathing rate and depth

Front

Chemoreceptors sensitive to carbon dioxide are located in the: Lungs, Heart, Aorta, Brainstem

Back

Brainstem

Front

What is the function of surfactant in the lungs?

Back

To reduce surface tension and prevent alveolar collapse

Front

Which cells in the alveoli are responsible for producing surfactant?

Back

Type II alveolar cells

Front

Tidal volume refers to:

Back

The volume of air inhaled and exhaled during normal breathing

Front

What is vital capacity?

Back

The maximum volume of air that can be exhaled after a maximal inhalation.
