This interrelation is essential for healthcare professionals to diagnose and treat medical conditions effectively. Choice B is incorrect because anatomy and physiology are indeed closely related.

The gallbladder stores bile produced by the liver and releases it to aid in the digestion of fats. Choice A is incorrect as the liver, not the gallbladder, filters blood and detoxifies harmful substances. Choice B is incorrect because the production of enzymes primarily occurs in the pancreas, not the gallbladder. Choice D is incorrect as the gallbladder's main role is not to further digest food but to store and release bile.
