Deoxygenated blood leaves the kidneys through the renal veins.
wastes
Water (e.g. a mixture of fluid) is excreted through the urine.Fluids are reabsorbed from the large intestines and then shuttled to the kidneys. The kidneys process fluids for excretion.

Most filtrate is reabsorbed. Remember, just about everything other than cells and large proteins is filtered into Bowman's capusle, and your body needs most of it, or else all you would have running through your blood are cells and proteins. The kidneys reabsorb most of the water, ions and nutrients in the filtrate.
Cellular waste is a broad term. The stuff your cells excrete are transported away by different systems. Much of the waste products and useless chemicals end up being filtered out by the kidneys and are then tossed out of the body through urinating. Carbon-dioxide, the waste gas produced by the cellular metabolism, is reabsorbed into the bloodstream and exits through the alveoli in the lungs.
Because the size of bacteria and virus molecules are too large too pass through the kidneys filtering system :)
Yes. The kidneys are part of the urinary system that eliminates unneeded and undesirable substances dissolved in water from the bloodstream. It goes from the kidneys through the urethra and out the penis. The more water available, the easier it is for the kidneys to do their job.
No. they are called nephrons. The ureters are large tubes that carry urine away from the kidney into the bladder.
As in any other mammalian species, the pig eliminates wastes through the umbilical cord, and then the mother's vascular system moves it back into her bloodstream. From there it is metabolized in her liver/kidneys. It all happens through the bloodstream until the pig is born and his own digestive system and kidneys kick in.
