What are the independent, dependent, constant and control variables in my experiment?

I am doing a science project, and I can't figure out what the variables would be. My scientific question is: How does the delivery method of a drug change how quickly it enters the bloodstream? I will be testing two different liquids, water and lemon juice, gel pills and regular pills, and coated vs, not coated. Answers would be greatly appreciated!

    The independent variable is the delivery method of the drug. coated regular pills, uncoated regular pills, coated gel pills, uncoated gel pills.

    The dependant variable is the amount of time it takes for the drug to enter the bloodstream.

    The control variable should be the mass of the pills. (This is becuase mass effects the rate of reaction)
