Verified step by step guidance1
Identify the key characteristics of the structures listed: urinary bladder, liver, heart, and stomach.
Understand that a 'hollow muscular sac' refers to an organ that is both hollow and has muscular walls, allowing it to expand and contract.
Analyze each option: The urinary bladder is a hollow organ that stores urine and has muscular walls to help expel urine. The liver is a solid organ involved in metabolism and detoxification. The heart is a muscular organ that pumps blood but is not hollow in the sense of storing substances. The stomach is a hollow organ that stores and digests food, with muscular walls to aid in digestion.
Compare the characteristics of each structure to the definition of a 'hollow muscular sac'.
Conclude that the urinary bladder and stomach fit the description, but the urinary bladder is more commonly referred to as a 'hollow muscular sac' in the context of storing and expelling substances.
