2nd semester: Renal 3 Flashcards
Having an impaired electron transport system is an example of
histotoxic hypoxia
What is the estimated oxygen content of the red blood cells if the patient’s Hgb level is 14g/dL?
18ml O2/dL
This describes the lower affinity of Hgb for carbon dioxide secondary to an increase in the partial pressure of oxygen in the lungs?
Haldane Effect
Factors that shifts the oxyhemoglobin dissociation curve to the right
Increased hydrogen ions
Increased basal metabolic rate
Alkalosis will cause a shift of oxyhemoglobin dissociation curve to the
LEFT
Oxygen delivery to tissues is determined by which of the following factor?
oxygen content of the blood
Bohr effect increases the _______ of ___ with Hgb
affinity, CO2
The ___ group contains inspiratory neurons that innervate the diaphragm and external intercostal and functions in every respiratory cycle whether quiet or forced
dorsal respiratory
The ___ group is normally dormant and lies in the ventro-lateral part of the medulla
ventral respiratory
It is an inspiratory-inhibitory reflex, increasing rate of breathing and a protective mechanism against pneumothorax
Hering Breuer Reflex
Delays the “shut off” of inspiratory center in the medulla prolonging inspiration?
Apneustic center
Part of the brain that is responsible for the conscious control of breathing?
cerebral cortex
what is activated when there is engorgement of pulmonary capillaries with blood and increase in the interstitial fluid volume?
juxtacapillary receptors
When the ___ is increased in the plasma, it can activate the central chemoreceptors and result to an increase in the respiratory rate?
PaCO2
The ventral respiratory group located in the ventro-lateral region of the medulla is composed of the following cell groups:
Caudal nucleus retro-ambiguus
Rostral nucleus retro-ambiguus
Nucleus para-ambiguus
