Respiratory System Flashcards

Front

What is the role of the visceral pleura?

Back

Attaches to the lungs completely covering them, preventing friction between the lungs and other organs.

Front

Breathing is controlled under what type of control? voluntary or involuntary?

Back

Involuntary or automatic control

Front

What does the Respiratory Centre in the brain do?

Back

Stimulates neurones in two areas of the medulla oblongata critical for respiration

Front

What is the role of the Medulla Oblongata in the brain?

Back

Responsible for involuntary functions like breathing and heart rate

Front

What is meant by chemical control of breathing when exercise begins?

Back

Changes in chemicals (less O2 and more CO2) in the blood stimulate the respiratory control centre, increasing the breathing rate.

Front

Role of neural receptors in muscles and joints during exercise?

Back

Neural receptors in muscles and joints detect movement and stimulate the respiratory control centre, increasing the breathing rate.

Front

Stimuli for the respiratory control centre during exercise

Back

Changes in chemicals in the blood and receptors in muscles and joints detecting movement.

Front

Type of control when receptors in muscles and joints affect breathing

Back

Neural control.

Front

What is the function of the epiglottis?

Back

Ensures food and drink pass into the stomach and not the lungs

Front

How does Tidal Volume and Vital Capacity adapt from long term training and exercise?

Back

Tidal Volume Increases

(volume of air in and out per breath)

more O2 per breath and more efficient

Vital Capacity Increases

(maximal amount of air that can be breathed out after a maximal inhalation) - lungs can hold and expel more air
