Which of the following best describes the primary role of the gall bladder in the human body?
A
It secretes insulin to regulate blood sugar levels.
B
It stores and concentrates bile produced by the liver.
C
It absorbs nutrients from digested food.
D
It produces digestive enzymes for protein breakdown.
Verified step by step guidance1
Understand the role of the gall bladder in the human body. The gall bladder is a small organ located beneath the liver and is part of the digestive system.
Recall that the liver produces bile, a substance that helps in the digestion and emulsification of fats. However, the liver does not store bile directly.
Recognize that the gall bladder's primary function is to store and concentrate bile produced by the liver until it is needed for digestion, particularly after consuming fatty foods.
Eliminate the incorrect options: The gall bladder does not secrete insulin (this is the role of the pancreas), it does not absorb nutrients (this is the role of the small intestine), and it does not produce digestive enzymes (this is also a function of the pancreas).
Conclude that the correct description of the gall bladder's primary role is: 'It stores and concentrates bile produced by the liver.'
