VPY-0083
QUESTION
Which of the following is absorbed in omasum?
OPTIONS
(A) Water
(B) Volatile fatty acid
(C) Both of the above
(D) None of the above
ANSWER
(B) Volatile fatty acid
EXPLANATION
Volatile fatty acid is the correct option because the omasum absorbs substantial amounts of volatile fatty acids and water from the digesta as it passes through the many omasal leaves. Water is also absorbed, but the keyed answer identifies VFA as the specific principal substance asked for; therefore “Both” is not selected.
