Pharmacokinetics- refers to the movement of the dug through the body that involves absorption, distribution, metabolization, and excretion. Pharmacodynamics- refers to the mechanism of action of drugs. Absorption- the effects of a drug on an organism depend on the rate of accumulation and the concentration of the drug and its site of action and the duration of contact at those sites. The absorption of bodily substances is affected by membranes. Capillaries- the bulk of the membrane activity occurs between the capillary walls and cell membranes, as materials moves out of the bloodstream into tissues. Capillaries service every cell and are crucial to absorption. The number of capillaries and the drug"s ability to penetrate their walls are major factors in determining how well the drug can enter body tissues.
