Which of the following is the strongest stimulus to increase respiratory rate?
Low oxygen levels
High carbon dioxide levels
Increased heart rate
Increased blood pressure
If your blood is low in carbon dioxide, how does your body respond?
Increase respiration rate
Decrease respiration rate
Increase heart rate

Match each term with its corresponding description.
Apnea
Cessation of breathing
Dyspnea
Difficulty breathing
-pnea
Breathing
Tachypnea
Abnormally fast breathing
Bradypnea
Abnormally slow breathing
Which of the following is characterized by an abnormally fast respiration rate that is not due to an increase in blood carbon dioxide levels?
Hypercapnia
Tachypnea
Hyperventilation
Hypoventilation
A person runs a mile and has a respiration rate of 38 breaths/min.
True or False: this would be considered tachypnea.
True
False
What is a normal adult resting respiration rate?
12-20 breaths/min
60-100 breaths/min
8-12 breaths/min
15-30 breaths/min
(a) is abnormally fast breathing without an underlying physiological reason.
(b) is abnormally fast breathing due to high carbon dioxide levels in the blood.
Why would breathing into a paper bag help treat hyperventilation?
It wouldn't; it does not work and is no longer recommended
It increases the amount of carbon dioxide inhaled in each breath
It decreases the amount of oxygen inhaled in each breath
It activates the sympathetic nervous system to slow heart rate and breathing
Why would sleeping cause the medulla oblogata to slow respiration rate?
Body cells are producing less carbon dioxide
Body cells need less oxygen at rest
It wouldn't; respiration rate would increase during sleeping
Sleeping doesn't have an effect on respiration rate
Which part of the body adjusts respiration rate in response to chemoreceptor signals from the bloodstream?
Medulla oblongata
Frontal lobe
Sympathetic nervous system
Sinoatrial node
Match each term with its description.
Hyperpnea
Rapid breathing due to exercise
Hyperventilation
Rapid breathing due to stress
Tachypnea
Rapid breathing at rest
Apnea
Temporary stopping of breathing
Bradypnea
Slow breathing at rest
If you have high lung compliance, would expiration be easier or harder?
Easier
Harder
