A&P II Exam 2 - Respiratory System

Which of these is not a function of the respiratory system?

-Supply body with oxygen for cellular respiration

-Dispose of carbon dioxide

-Supply body with carbon dioxide for respiration

-Speech

Supply body with carbon dioxide for respiration

Pulmonary ventilation is the:

-Exchange of carbon dioxide and oxygen between the lungs and blood

-Transport of oxygen and carbon dioxide in the blood by the circulatory system

-Movement of air in and out of the lungs

-Exchange of oxygen and carbon dioxide between systemic blood vessels and tissues

Movement of air in and out of the lungs

Which of these is not a function of the nose?

-Provide an airway for respiration

-Speech

-Moisten and warm entering air

-Filters and cleans inspired air

-Serves as a resonating chamber for speech

-Houses olfactory receptors

Speech

Which of these is a region of the pharynx?

-Oropharynx

-Larynx

-Epiglottis

-Vestibular fold

Oropharynx

What type of cells line the bronchioles?

Cuboidal epithelial cells

Inflammation of the vocal folds that causes the vocal folds to swell, interfering with vibration

Laryngitis

Inflammation of the nasal mucosa due to viral infection or allergies, can lead to a sinus headache

Rhinitis

This action causes the destruction of cilia, so coughing is the only way to prevent mucus from accumulating in the lungs

Smoking

Inflammation pleurae that often results from pneumonia

Pleurisy

Thickness of respiratory membrane increased dramatically if the lungs become waterlogged and edematous

Pneumonia

This cleanses the air that enters the respiratory system

Cilia

Pulmonary ventilation is also known as

Breathing

Exchange of gases between the air and blood is ___ and the exchange of gases between blood and tissue fluid is ___

External respiration; internal respiration

Identify the function of the mucous membrane lining respiratory airways

Clean, warm, and moisten air

Identify the structures of the upper respiratory tract:

-Alveoli, nasal cavity, pharynx, and trachea

-Bronchus, nasal cavity, pharynx, and larynx

-Nasal cavity, pharynx, glottis, and paranasal sinuses

-Trachea, nasal cavity, pharynx, and larynx

Nasal cavity, pharynx, glottis, and paranasal sinuses

Identify the sections of the pharynx in order as air is inhaled:

-Laryngopharynx, nasopharynx, oropharynx

-Nasopharynx, laryngopharynx, oropharynx

-Nasopharynx, oropharynx, laryngopharynx

-Oropharynx, nasopharynx, laryngopharynx

Nasopharynx, oropharynx, laryngopharynx

Identify the structure that keeps food and drink from entering the lower respiratory tract

Epiglottis

The voice box is also called the ___

Larynx

The windpipe is also known as the ___

Trachea

The trachea is lined with

Pseudostratified ciliated columnar epithelium

The right lung has ___ secondary bronchi and the left lung has ___ secondary bronchi

3;2

The serous membrane adhering to the surface of the lungs is the ___ and the serous membrane that lines the thoracic cavity is the ___

Visceral pleura, parietal pleura

The trachea divides into the right and left ___ that enter into the right and left lungs

Primary bronchi

During gas exchange within the lungs, oxygen diffuses from the ___ into the blood of the ___

Alveoli; pulmonary capillaries

Identify muscles of inspiration:

-Abdominal muscles and external intercostal

-Diaphragm and external intercostal muscles

-Diaphragm and internal intercostal muscles

-Internal and external intercostal muscles

Diaphragm and external intercostal muscles

The exchange of gases between the blood and tissue fluids is called

Internal respiration

During expiration, the diaphragm relaxes, causing the volume of the thoracic cavity to ___ and the intrapulmonary pressure to ___

Decrease; increase

Airflow into the lungs will stop when the pressure in the air (atmospheric pressure) is

Equal to intrapulmonary pressure

We exhale oxygen rich air from our lungs; T or F

False

Which of the following delivers air to the lobes of the lungs?

-Primary bronchi

-Secondary bronchi

-Tertiary bronchi

-Terminal bronchioles

Secondary Bronchi

All of the following are part of the conduction zone except the ___

-Main bronchi

-Respiratory bronchioles

-Segmental bronchioles

-Terminal bronchioles

Respiratory bronchioles

An increase in the volume of a container filled with air would have what effect on the pressure of the container?

Decrease in the pressure

Which of the following statements is FALSE in regard to inspiration?

-The rib cage is elevated

-The diaphragm is relaxed

-Intrapulmonary pressure has decreased

The diaphragm is relaxed

When holding our breath for a long time we get the urge to breathe because of ___

An increase in CO2

The space at the back of the mouth, that leads either to the airway or the esophagus is the

Pharynx

When the diaphragm contracts (is pulled downward), ___ occurs

Inhalation

Most of the oxygen in the blood is transported

Attached to the heme group of the hemoglobin in red blood c
