This stock medical exhibit describes the effect of heparin on the blood vessels. It includes three illustrations describing the normal anatomy and physiology involved in the clotting. Two additional illustrations compare the effects of a low and a high dose of heparin on the blood vessels.

The Use of Coumadin in Preventing Venous Thrombus Formation - Medical Chart

On the right under content tools, there is a "Magnify" option that I found useful. I don't think Coumadin is commonly being used these days. I'll check for a Plavix one too.
Haven't found a Plavix chart but I did find this:

A new boxed warning has been added to the anti-blood clotting drug Plavix by the Food and Drug Administration, who says the medication doesn't work well in people who have difficulty metabolizing the drug.
Plavix needs to be activated by the liver enzyme, CYP2C19. Patients that have reduced liver enzyme function can't activate the drug making it less effective for them. They're called "poor metabolizers" and this puts them at greater risk of heart attack, stroke and death.
"We want to highlight this warning to make sure health care professionals use the best information possible to treat their patients," said Mary Ross Southworth, a clinical analyst in the Division of Cardiovascular and Renal Products in the FDA's Center for Drug Evaluation and Research.
The Agency says there are tests available to evaluate CYP2C19 and determine if you are a "poor metabolizer." They say patients should talk to their doctors to determine if they should stop taking the drug.
