The voltage delivering 1 watt depends on how many amps are present. We use watts to measure power (P), and amps (I) times volts (E) equals watts.
The liver and the production of urea Urea is a nitrogen-containing substance which is produced in the liver, in order to deal with excess amino-acids in the body, which is a natural consequence of the fact that we almost always eat more protein than our body needs to assimilate. The process is called deamination.
Uremia is a condition marked by elevated levels of urea in the blood. Urea is the waste by-product of protein breakdown. Healthy kidneys remove urea from the blood and uremia can be a sign that your kidneys are shutting down. Uremia is very dangerous and can lead to heart and brain failure.
