Question
Chapter 43, Problem 1S
Summary Introduction
To determine:
How does the body sense the change, when pH falls too low, how does the breathing rate change, and how does this increase pH.
Introduction:
The sensory receptors detect the external and internal stimuli, and in response to the stimuli send impulses to the brain. The sensory receptors, which are responsible for determining the pH of the blood and cerebrospinal fluid, are chemoreceptors.

Some patients with hypertension (high blood pressure) are given beta-blocking drugs to lower their blood pressure. How does this effect occur? Explain why these drugs are not administered to patientswith a history of asthma. Why might drinking coffee help asthma?
When a patient has a severe allergic reaction, a common prescribed drug is epinephrine. Which of the follow best explains the effects of epinephrine on a patient experiencing a severe allergic reaction?
A epinephrine binds to the beta-1 receptor. Activating the beta-1 receptor causes vasodilation and bronchoconstriction. Bronchoconstriction allows the patient to breath by relaxing the smooth muscle that is constricting the airway.
B Epinephrine binds to the beta-2 receptor. Activating the beta-2 receptor causes vasodilation and bronchodilation. Bronchodilation allows the patient to breath easier by relaxing the smooth muscle that is constricting the airway.
C Epinephrine binds to the alpha-1 receptor. Activating the alpha-1 receptor causes vasodilation and bronchodilation. Bronchodilation allows the patient to breath by relaxing the smooth muscle that is constricting the airway.
D Epinephrine binds to the beta-1 receptor. Activating the beta-1 receptor causes vasodilation and…

- On a hot day, a runner begins to have trouble breathing and becomes pale, dizzy, and nauseated. From what condition is this runner likely to be suffering?arrow_forwardWhich one of the following statements about the afferent components of the respiratory control system is INCORRECT? Select one: a. In order to stimulate hyperventilation the sympathetic nervous system tricks the carotid body by constricting the capillaries that serve glomus cells; reduced blood flow to the cell causes localised hypoxia triggering a compensatory hyperventilation response even before systemic hypoxia is apparent. b. In type 1 glomus cells of the carotid bodies, hypoxia, hypercapnia and acidosis trigger afferent signalling by inhibiting K+ channels, depolarising the cell membrane, and opening voltage-gated Ca2+ channels that trigger the release of neurotransmitters onto afferent glossopharyngeal nerve fibres. c. Chemoreceptor cells can be found in the carotid body. d. The glossopharyngeal nerve transmits afferent impulses from the carotid body to the ventral respiratory group of neurons.arrow_forwardWe noted in Chapter 10 that dogs are believed to benefit when they pant by breathing at a fixed resonant frequency. Although dogs inhale and exhale exclusively through the nose when not under heat stress, they exhale orally to some (variable) extent when panting. Air exhaled by way of the mouth remains nearly at deep-body temperature. Explain how a panting dog could vary its rate of evaporative cooling—even while breathing at a fixed frequency—by modulating how much it exhales by way of its nose or mouth.arrow_forward

- Describe what happens in the respiratory system when you run to catch a bus by placing the following in order (#1-7). Consider that the running will have caused an increase in cellular respiration, which results in an increase in CO2 (this is the change in the variable). The increase in CO2 will be detected by the brain, which will ultimately cause an increase in ventilation. Blood CO2 levels increased and O2 levels decreased. Increased ventilation results. Chemoreceptors detect decreased O2 and increased concentration of CO2/decreased pH. Return to normal CO2 and O2 levels. Respiratory centers increases its stimulation of spinal nerves (phrenic and intercostal). Increased frequency and degree of contraction of respiratory muscles. Central and peripheral chemoreceptors stimulate the respiratory centers in the brainstem. Increased cellular respiration in response to the running.arrow_forwardRegarding central chemoreceptors, if H+ ions are unable to cross the blood-brain barrier, how does the brain detect a change in the body's pH?arrow_forwardA behavioral physiologist is studying the homeostatic control of blood pH.
