We have the soil, the decaying body of the host (no life, dead cell), the atmosphere and gases and temperature & climate.
The nitrogen cycle is one of the biogeochemical cycles that occurs to maintain balance and matter distributed through the biosphere. This cycle enables nitrogen to develop from a decaying organism back to the air and used again for other natural processes.
Alcohol can pass directly into the bloodstream from the mouth or stomach is a true statement.
On consumption of alcohol it travels from mouth to stomach, then into the circulatory system, kidney, liver, lungs and brain. Alcohol being a small molecule does not need any digestion in stomach and passes to the bloodstream directly in an empty stomach. When food is present in stomach, the absorption rate is reduced but is not stopped.
Once the alcohol is in the bloodstream, it gets evenly distributed throughout the body.
