Exam 17: Respiratory System

Eupnea refers to a normal respiratory rate.

Laryngitis can be caused by either bacteria or a virus.

Briefly describe the structure of the nose. Describe the paranasal sinuses and their function.

If internal respiration is working properly, the blood leaving the tissues will have less oxyhemoglobin and more carbaminohemoglobin than the blood entering the tissues.

Match each of the following terms with its corresponding definition or description. -How most of the oxygen is carried in the blood

Match each of the following terms with its corresponding definition or description. -Tubes that branch from the trachea and contain cartilage as part of their structure

The mucous blanket covers all of the structures of the respiratory system except the epiglottis.

Explain why the number of tonsillectomies has dropped in recent years.

Describe rhinitis. What are some of its causes?

Which of the following bones does not contain a paranasal sinus?

From superior to inferior, the parts of the pharynx are oropharynx, nasopharynx, and laryngopharynx.

Neither internal respiration nor cellular respiration occurs in the lung.

Match each of the following terms with its corresponding definition or description. -Small air distribution tubes that have walls without cartilage

Residual volume is considered part of expiratory reserve volume.

If external respiration is working properly, the blood leaving the lung will have more oxyhemoglobin and less carbaminohemoglobin than the blood entering the lung.

The two most important respiratory control centers for regulating breathing are located in which part of the brain?

Explain the process of normal expiration.

One of the functions of the mucous blanket is the removal of contaminants from inhaled air.

Explain how the structure of the alveoli increases the efficiency of gas exchange in the lungs.

For gas exchange to occur in the lungs, the alveoli must have a higher oxygen content than the blood and a lower carbon dioxide content than the blood.
