The movement of medication from the blood to the body tissues is described as **Distribution**.
Here's how it happens:
1. **Absorption:** Medication is absorbed into the bloodstream after being taken through various routes like oral ingestion, injection, or inhalation.
2. **Distribution:** Once in the bloodstream, the medication is carried to different parts of the body through circulation. This process involves the medication being transported to various tissues and organs where it is needed.
3. **Metabolism:** After distribution, some medications undergo chemical changes in the body, known as metabolism. This process can activate, deactivate, or change the medication into substances that can be eliminated from the body.
4. **Excretion:** Finally, any medication or its metabolites that are not needed or harmful are eliminated from the body through organs like the kidneys, liver, or lungs.
Therefore, when medication moves from the blood to the body tissues, it is referred to as the distribution phase.
