Verified step by step guidance

Step 1: Begin by understanding the anatomical structure and function of the bladder. The bladder is part of the urinary system, which is responsible for storing and expelling urine produced by the kidneys.

Step 2: Recognize that the bladder is a hollow organ, meaning it has an internal cavity that can expand to hold urine. This distinguishes it from solid organs like the liver or kidneys.

Step 3: Note that the bladder is muscular, composed of layers of smooth muscle called the detrusor muscle. These muscles contract during urination to expel urine.

Step 4: Clarify the bladder's role in the urinary system. It does not filter blood (a function of the kidneys) or produce digestive enzymes (a function of glands like the pancreas). Instead, it stores urine until it is expelled through the urethra.

Step 5: Conclude that the most accurate description of the bladder is 'a hollow muscular organ that stores urine,' as this aligns with its anatomical structure and physiological function.
