Which one of the following is the correct sequence of organs that occur in the path of urine flow in the human body?

The human excretory system follows a specific anatomical sequence for the production and elimination of urine. The process begins in the kidneys, where blood is filtered to remove nitrogenous wastes like urea [1]. The urine formed in each kidney then enters a pair of long tubes called ureters [2]. These ureters conduct the urine from the kidneys down to the urinary bladder, a muscular sac located in the pelvic cavity that serves as a temporary storage reservoir [1]. Once the bladder expands and creates the urge to urinate, the urine is finally expelled from the body through a single tube-like structure known as the urethra [2]. Therefore, the correct physiological path of urine flow is Kidney → Ureter → Urinary Bladder → Urethra [1].
