The advantage is that ammonia (NH3) is not converted in Ammonotelic excretion. Fish can excrete ammonia through gills because there is a lot of water to dilute it in without causing damage to their cells. In Uricotelic excretion, NH3 has to be converted to a solid form via a complex and ATP-costly route. So Uricotelic excretion takes a lot more energy than Ammonotelic excretion.
Irritating drugs and thick suspension are not suitable to be injected via the subcutaneous route.
The skin produces sweat, but this is not really an excretion. The main function of sweat is to help cool the body. However sweat also contains small amounts of urea, the main waste found in the urine. The concentration of urea in sweat is much less than that in the urine, so this is not a significant route for excretion. Sweat also contains samll amounts of salts (minerals), but again the urine is the main route for the elimination of excess salt.

Drugs given orally enter the body by way of traveling through the mouth and into the GI system. Drugs given parenteraly enter through the blood stream (IVs, for example) and act within the body must faster than those given orally. There is a higher risk for infection or complication with parenteral administration than with oral.
a drug route is a plan/places that drug dealers go to sell their drugs. its kinda self exsplanitory
This trade route was known as the Varangian Route. The Route connected Europe to Asia through the Russian territory.
The oral route of administration.
Most take medications at home and do not have the training nor the equipment to do so. Only drugs designed and intended for administration via a parenteral route should be taken that way. If drugs designed to be taken orally are administered parenterally the "user" could be harmed, and the medication may work very differently than intended. In addition, most drugs are tested as orally administered medications. The way they are absorbed, how they are metabolized, and the dose and time to effect are all designed for oral administration.

The four ways the body can eliminate toxins are Biotransformation, excretion by the kidneys, excretion by the liver and excretion by the lungs. It all depends on what the toxin is i.e Lipo soluble or water soluble and also the concentrations together with the route of exposure how the body will try to eliminate the toxin.
