Which structures have ciliated cells that produce mucus

• alveoli

What is the function of the pleural membrane?

• to ensure your lungs move with your thoracic wall

• to trap pathogens entering your lungs

• to contract and move your lungs down when you inhale

• to relax and move your lings up when you inhale

What is the function of the alveoli?

• get air inside your body

• gas exchange with outside environment

• contract down to help you inhale

• gas exchange with cells

Which of the following is internal respiration?

• getting air inside your lungs

• gas exchange between lungs and blood

• gas exchange between blood and cells

• create ATP from glucose in cells

Which of the following is true for inhalation?

• diaphragm and intercostal muscles contract causing low pressure in lungs

• diaphragm and intercostal muscles relax causing low pressure in lungs

• diaphragm and intercostal muscles contract causing high pressure in lungs

• diaphragm and intercostal muscles relax causing high pressure in lungs

Which of the following is external respiration?

• getting air inside your lungs

• gas exchange between lungs and blood

• gas exchange between blood and cells

• create ATP from glucose in cells

If you had a condition that broke down the walls of your alveoli, you may experience

• shortness of breath due to less air getting into your lungs

• less gas exchange between lungs and blood

• less gas exchange between blood and cells

• shortness of breath due to less air getting into your bonchioles
