Final answer:
Urine is temporarily stored in the urinary bladder, which is a hollow and stretchy organ that collects and holds urine until urination.
Step-by-step explanation:
The answer to the question "Urine is temporarily stored in the _____" is E) urinary bladder. The urinary bladder is a hollow, muscular, and stretchy organ situated on the pelvic floor. It serves as a temporary reservoir for urine that has been filtered by the kidneys and transported to it via the ureters. The bladder collects and stores urine until it is excreted from the body during urination. The urine then leaves the bladder, passing through the internal urethral sphincter and into the urethra, ultimately being released outside the body.
