Question 341 Mark
$pH$ of blood in artery and vein is:
Answer
View full question & answer→$pH$ of blood is more in the vein as compared to that in the artery as the plasma of the vein contains deoxygenated blood and dissolved $CO_{2}$ in the form of bicarbonate ions.
These ions increase the alkalinity of the plasma, therefore the $pH$ value of blood is greater in the vein as to that of the artery
So, the correct answer is 'More in vein and less in artery'
