Urine is produced in the kidneys. It flows through tubes called ureters into the bladder. Urine leaves the body through the urethra. The bladder muscle helps you urinate by squeezing to force the urine out. A thin surface layer called the urothelium lines the inside of the bladder. Next is a layer of loose connective tissue called the lamina propria. Covering that tissue is the bladder muscle.
