what happens after neo takes the red pill
Red pill and blue pill Neo takes the red pill and awakens in the real world, where he is forcibly ejected from the liquid-filled chamber in which he has been lying unconscious. After his rescue and convalescence aboard Morpheus's ship, Morpheus shows him the true nature of the Matrix: a detailed computer simulation of Earth at the end of the 20th century (the actual year, though not known for sure, is approximately two hundred years later). It has been created to keep the minds of humans docile while their bodies are stored in massive power plants, their body heat and bioelectricity consumed as power by the sentient machines that have enslaved them.
First pass effect After a drug is swallowed, it is absorbed by the digestive system and enters the hepatic portal system. It is carried through the portal vein into the liver before it reaches the rest of the body. The liver metabolizes many drugs, sometimes to such an extent that only a small amount of active drug emerges from the liver to the rest of the circulatory system. This first pass through the liver thus greatly reduces the bioavailability of the drug.
