ACTUAL Exam Questions and CORRECT
Answers
After passing through the tissues, blood is said to be deoxygenated. What does this mean? -
CORRECT ANSWER - Some of the oxygen that was loaded into the blood has been
released at the tissues. There is less oxygen in the blood after passing through the tissues.

CORRECT ANSWER - a decrease in the concentration of epinephrine circulating around
in the blood
