http://en.wikipedia.org/wiki/Gung-ho Gung-ho is a phrase borrowed from the Chinese language, frequently used in Chinese as an adjective meaning enthusiastic.
The ureters are a pair of small tubes that connect the kidneys to the urinary bladder. They form a vital link in the urinary tract by allowing urine to drain from the kidneys to be stored in the bladder. The ureters are thin, muscular tubes found within the abdominopelvic cavity.
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.
