Hint: The primary function of a gallbladder, is to store bile (produced by the liver), which helps in the digestion of food, specifically the fat. It is present in many animals/mammals like - humans, dogs, cows, sheep, and lions.
Complete answer: The bile which is stored in the gallbladder, is produced by the liver and it is used in the digestion of fats, in the intestines.
We as humans, eat few but larger meals, comparatively. So, our gallbladder functions as a storage pouch for bile (it is an emulsifying agent which is produced by the liver, and it is required to begin the digestion of fat).
The bile is released by gallbladder, as and when needed. When we eat a large amount of fat at one time, the gallbladder releases bile into the small intestine to help in the digestion.
While horses eat continuously, but in small amounts, i.e. they have to continuously graze on grass or hay.
The little fat which is consumed by them, is managed very easily by the liver. Thus, they don’t need to store the bile in larger quantities.
The bile is constantly released into the small intestine, irrespective of the presence or absence of food for digestion.
So, according to the information mentioned above, the correct answer is “Option A”.
Note:
If a horse has to stay even for a few hours, without eating, it will start to look very weak and ill, because of the build-up of bile in its bloodstream.
So horses need to eat the food constantly to maintain good health, but this is not so for other animals which possess a gallbladder.
