True or False: The pneumotaxic center is required for normal breathing (eupnea). |
Card: 31 / 60 |
In the context of high altitude, what effect does hypoxia have on pulmonary circulation? |
Card: 37 / 60 |
It causes hypoxic pulmonary vasoconstriction, leading to increased pulmonary arterial pressure. |
Card: 38 / 60 |
Fill in the blank: The ______ curve shifts left due to respiratory alkalosis at high altitudes. |
Card: 39 / 60 |
It depresses the central nervous system, causing confusion and potentially coma. |
Card: 42 / 60 |
Riddle: I can make you breathe faster, but only when my partner is low. Who am I? |
Card: 43 / 60 |
What is the relationship between PaO₂ and ventilation in a healthy individual? |
Card: 45 / 60 |
True or False: The J-reflex is primarily responsible for controlling normal breathing patterns. |
Card: 47 / 60 |
Which reflex inhibits further inspiratory muscle activity when the lungs are inflated? |
Card: 49 / 60 |
Fill in the blank: The main effect of Hering-Breuer's reflex is to decrease the ______ rate by increasing expiratory time. |
Card: 51 / 60 |
What is the main physiological adaptation in response to high altitude concerning blood? |
Card: 55 / 60 |
Increased erythropoietin release leading to increased red blood cell production. |
Card: 56 / 60 |
Fill in the blank: ______ is defined as pain in joints and muscles resulting from decompression sickness. |
