The body reacts to the drugs by transforming them in the liver to eliminate them, through the process of biotransformation.

The term "biotransformation" refers to the various chemical changes that drugs undergo in the body to give rise to metabolites. The biotransformations are mainly carried out by enzymatic reaction. A drug can undergo several biotransformations resulting in the formation of several metabolites.

The main function of biotransformations is to make water-soluble lipophilic molecules to promote the elimination of the body: indeed, the lipophilic molecules pass the membranes during the absorption and distribution phases, but conversely their liposolubility does not allow their renal elimination in unchanged form. They will either be excreted directly via the bile ducts or biotransformed before renal or biliary excretion. Some drugs do not undergo biotransformations: they are said to be eliminated from the body in unchanged form.

In general, biotransformations are defense reactions of the body that lead to less toxic and less active molecules than the parent molecule. Nevertheless, the metabolites may also be more active or more toxic than the drug administered. When the active ingredient is inactive and its metabolite is active, the drug is called "prodrug". For example, valganciclovir is a prodrug of ganciclovir.

The biotransformations of the drugs are essentially hepatic and intestinal even if there is also a pulmonary, renal or plasma metabolism. There are two types of biotransformations, classified in Phase I and Phase II (functionalization reaction and conjugation reaction).

Which of the following prevents blood from flowing backward through the circulatory system?
netineya [11]

Answer: Valves in the veins

Explanation: The flow of the blood inside the body takes place through the veins and arteries. The oxygenated blood from the heart is supplied to the different parts of the body.

The blood flows from the capillaries to the venules and from there to the veins. The blood moves in the veins by the rhythmic movement of the smooth muscles in the body.

Most of the blood moves against the gravity so there is a chance that it can backflow so to prevent this there are valves in the veins known as one way valves.

When birds breath in, their posterior air sacs inflate with air from the outside, and their anterior air sacs inflate with air from the lungs. When they breath out the air that was then in the posterior air sacs is now pushed to the lungs, and the air that was in the anterior air sacs is expelled through the trachea.</span>
