Respiratory System

Match the following

• External respiration

• The exchange of oxygen and carbon dioxide

• Internal respiration

• The physical act of breathing in and out

• Pulmonary ventilation

• The exchange of oxygen and carbon dioxide between air in the lungs and bloodstream

• Respiration

• Cells convert sugars and other nutrients to energy

• Cellular respiration

• The exchange of oxygen and carbon dioxide between the bloodstream and body's tissues

Prevents food from going in the lungs

• Epiglottis

• Larynx

• Thyroid cartilage

• Cricoid cartilage

During inhalation the ​ (a)   between the ribs and the diaphragm ​ (b)   . This causes the thoracic cavity to ​ (c)   which ​ (d)   lung volume.

• intercostal muscles
• contract
• expand
• increases
• decreases
• relax

The nasal cavity and sinuses are similar how?

• have mucous membranes that trap dust / particles / pathogens + warm air

• both add resonance to the voice

• both contain cilia that help move mucus to the pharynx

• both protect and support the vocal cords

Reorder how oxygen travels:

• trachea

• Alveoli

• bronchiole

• bronchi

COPD is a term for chronic condition that cause recurrent blockage of airflow in the lungs, which is not an example

• Emphysema

• Pneumonia

• Chronic bronchitis

• Chronic obstructive asthma

What best describes COPD

• infection in the lung requiring antibiotics

• Fluid retention in the lungs

• Cancer requiring treatment

• Impaired gas exchange

The lungs are unique how?

• 2 lobes right

  3 lobes left

• 2 lobes right

  2 lobes left

• 3 lobes right

  3 lobes left

• 3 lobes right

  2 lobes left

Match the following

• extends epiglottis to cricoid cartilage, where the pharynx divides into esophagus / larynx

• Oropharynx

• connects nasal cavity to pharynx just above soft palate

• Nasopharynx

• middle of pharynx, connect mouth to pharynx, contains muscle responsible for swallowing

• Pharynx

• throat, functions as passageway for air moving from nasal cavity and food moving towards esophagus

• Laryngopharynx

The epiglottis is

• in the up position all the time regardless of swallowing

• allows food to enter the trachea

• allows food to enter the esophagus
