BMS 420 Final Exam Study Questions
With Correct Answers
Homeostasis - ANSWER✔✔✔-Regulation of acid base balance to
| | | | | | | |
maintain normal physiological function
| | |
Pre-Botzinger complex - ANSWER✔✔✔-- basic respiratory rhythm
| | | | | | |
- respiratory pattern generator is located here
| | | | | |
Hypoxemia produces hyperventilation by a direct effect on the -
| | | | | | | | | |
ANSWER✔✔✔-carotid and aortic body chemoreceptors | | | |
Most important factor in the control of VENTILATION under normal
| | | | | | | | | |
conditions is - ANSWER✔✔✔-PaCO2
| | |
Hyperventilation - ANSWER✔✔✔-- Greater degree of voluntary control
| | | | | | | |
can be exerted over the output from the medullary respiratory center
| | | | | | | | | | |
during this |
- CO2 removal from the lungs that exceeds its production by the tissues
| | | | | | | | | | | |
, Increased PaCO2 - ANSWER✔✔✔-results in an INCREASE in alveolar
| | | | | | | | |
Ventilation (VA) |
Peripheral chemoreceptors - ANSWER✔✔✔-- sensitive to LOW PaO2
| | | | | | | |
values
Shallow-water blackout occurs due to - ANSWER✔✔✔--
| | | | | | |
unconsciousness due to hypoxia BEFORE the CO2 trigger to breathe is
| | | | | | | | | | |
reached |
- influenced by suppression of hypoxic ventilatory response
| | | | | | |
Hypoxic Hypoxia - ANSWER✔✔✔--Low arterial PO2
| | | | |
-High altitude, alveolar hypoventilation, decreased lung diffusion
| | | | | | |
capacity, abnormal ventilation-perfusion ratio
| | |
- reduced partial pressure of oxygen in the breathing gas or alveoli
| | | | | | | | | | |
Metabolic Alkalosis - ANSWER✔✔✔-- elevation of HCO3- usually caused
| | | | | | | |
by an excessive loss of metabolic acids
| | | | | | |
- elevated plasma pH
| | |
Respiratory Alkalosis due to hyperventilation - ANSWER✔✔✔-- for the
| | | | | | | | |
paper bag method, rebreathing CO2 reestablishes a proper blood CO2
| | | | | | | | |
