Why Does Arterial Blood Have a Lower Hydrogen Ion Concentration

question 2

Multiple Choice

Why does arterial blood have a lower hydrogen ion concentration than venous blood?

• A) More carbon dioxide remains in the arterial blood leaving the lung capillaries, causing an increase in the amount of carbonic acid and the number of hydrogen ions.
• B) Because there are more red blood cells in arteries than veins, the arterial blood has a greater ability to carry fewer hydrogen ions.
• C) Less carbon dioxide remains in the arterial blood leaving the lung capillaries, causing a reduction in the amount of carbonic acid and the number of hydrogen ions.
• D) The carbon dioxide diffuses out of the venous blood as it moves through the lung capillaries. Therefore, more carbon dioxide remains in the arterial blood leaving the lung capillaries, causing a decrease in the number of hydrogen ions.
