Respiratory System Review

What part of the respiratory system is responsible for gas exchange from air to blood?

• trachea
• nose
• bronchi
• alveoli

The reason we breath is so that our cells can make energy.  The formula for cellular respiration is

• a.  Glucose and oxygen → ATP and carbon dioxide and water
• a.  ATP and glucose → oxygen and carbon dioxide and water
• a.  Oxygen and water → ATP and carbon dioxide and glucose

what keeps food from going down your trachea?

• uvula
• alveoli
• epiglottis
• pharynx

If you have COPD, (chronic obstructive pulmonary disease), it is difficult for you to expire (breath out). We test this by blowing out a respirometer.  This test is called__ (see notebook pg 170)

• bronchoscopy
• pulmonary function test
• tracheotomy
• inhaler

If you have lung cancer, a physician might do a procedure to navigate into your lungs through the bronchi tubes to look at or take a biopsy of the cancerous tissue.  This procedure is of looking down these tubes is called (see notebook pg 173)

• tracheotomy
• pulmonary function test
• bronchoscopy
• inhaler

The primary role of the cilia and mucus in the nostrils (nose) is to 

• identify smells in the air
• warm air before it moves to lungs
• filter and trap any particles in air before it moves to the lungs
• move air in the right direction towards the mouth

INspiration is moving air IN to the lungs.  Inspiration occurs when __ muscle contracts and causes the lungs and thoracic cavity to ___ (remember pressure and volume physics law)

• diaphragm contracts and enlarges lungs and chest
• diaphragm contracts and makes lung volume smaller
• pectoralis contracts and enlarges lungs and chest
• pectoralis contracts and makes lung volume smaller

If you have asthma, your bronchial tubes can be inflamed and get more narrow.  Often you will be prescribed an inhaler which contains a drug that __ (notebook page 173)

• dilates your bronchioles
• constricts your bronchioles
• kills your bronchial cilia
• causes bronchioles to produce more mucus

Frequent coughing, bloody sputum and sweating profusely at night are symptoms of what respiratory infectious disease? (notebook page 172)

• bronchitis
• pneumonia
• tuberculosis

Heavy smokers often get the following symptoms:  chronic cough, bluish tint to skin, barrel shaped chest and reduced volume of air expired.  These are symptoms of __ noninfectious respiratory disease. (notebook pg 173)

• asthma
• emphysema (type of COPD)
• cystic fibrosis
• SIDS (sudden infant death syndrome)
