pH balance of blood Flashcards
what is the range of blood pH
7.35-7.45
what pH is acidosis considered and why is it dangerous
<7.35
dangerous b/c it can denature proteins and less excitability of neurons
what pH is alkalosis considered and what are the effects
> 7.45 it caused neurons to be more excitable
what are the three biggest regulators of blood pH
- blood buffers
- respiratory system
- renal system
describe the function of blood buffers
what are some of the buffers
do NOT change the pH of blood only stabilize it
buffers include: hemoglobin, plasma proteins, phosphate ions
what does the respiratory system regulate and how
CO2 (biggest source of acid) via ventilation rates
what is the pathway of CO2
chemoreceptors (aorta and carotid) -> medulla -> diaphragm contraction (phrenic nerve)
how does the renal system regulate blood pH
controlling [H+] and [HCO3-] in the plasma
how does the renal system control the [H+] and [HCO3-] in the plasma
via H+ secretion and HCO3- reabsorption
