The series of organs in this system function to produce, store, and eliminate
soluble waste products from the body. The filtrates from the kidney are transported by
the ureter to the bladder for storage, and are eliminated by way of the urethra. A major
function of the system is to salvage water, sugars, and ions from the filtrate and return
them to the blood. In addition, specialized structures within the kidney secrete the
vasopressor renin, which increases systemic blood pressure.
