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.
The kidneys make urine when they filter the blood. Urine flows from the kidneys through a pair of thin tubes, the ureters, to the bladder, where it is stored until a person urinates. During urination, muscles in the wall of the bladder contract, forcing urine out of the bladder and into a tube called the urethra. At the same time, the sphincter muscles that surround the urethra relax. Nerves carry messages from the bladder to the brain, telling the brain that the bladder is full.
