The respiratory system has two main functions for the human body. The first function is to bring O2 into our blood to deliver to cells throughout the body. We need O2 for our cells to live and function. The second main function is to:

Enable us to project our voice.

Remove carbon dioxide from our body, which is a waste product of cellular function.

Aid in supporting digestive system.

None of the above.

12.

1 point

COPD has two PRIMARY underlying disorders. Which of the following is one of the underlying disorders?

Pneumonitis

Pulmonary effusions

Emphysema

Pneumonia

13.

1 point

Which of the following statements regarding respiratory failure are true?

Lungs continue to perform their basic function of gas exchange.

Respiratory failure always requires mechanical ventilation.

A state where oxygen is too low but also a state where CO2 is too high.

Loss of elasticity in the lungs does not impact respiratory failure.

14.

1 point

Which respiratory infection is the most common cause of death from infection?

Acute bronchitis

Pneumonia

Bronchiectasis

Pleurisy

1 point

Cor pulmonale is defined as which of the following?

Failure of left side of heart with chronic hypertension.

Failure of left side of hear with long-term high blood pressure in pulmonary arteries.

Failure of right side of heart with chronic hypertension.

Failure of right side of heart with long-term high blood pressure in pulmonary arteries.

17.
