What is the term for the fraction of an administered dose of unchanged drug that reaches the systemic circulation?

Step 1: Understand that when a drug is given to a patient, it can be in different forms like a pill, injection, or liquid.
Step 2: Realize that not all of the drug given will enter the bloodstream unchanged; some may be broken down or not absorbed.
Step 3: Learn that 'systemic circulation' means the drug is in the bloodstream and can affect the whole body.
Step 4: Know that 'bioavailability' is the term used to describe how much of the drug actually gets into the bloodstream unchanged.
Step 5: Conclude that bioavailability is important because it helps determine how effective a drug will be.
