Three groups of drugs are used to reduce the stickiness of platelets, the tiny blood elements that form the nucleus of a blood clot. By inhibiting the ability of platelets to clump together, the anti-platelet drugs inhibit blood clotting. These drugs are most effective in preventing abnormal blood clots from forming in arteries and are much less effective at preventing thrombosis in the veins. Aspirin and dipyridamole (Aggrenox). These drugs have a modest effect on platelet stickiness but cause fewer bleeding-related adverse effects than the other anti-platelet drugs.
The middle layer of an artery and vein contains mostly. connective tissue. simple squamous epithelium. smooth muscle. nervous tissue. 2.

Arteries. Arteries carry blood which is full of oxygen away from the heart. Arteries have three layers of tissue-the outside and inside layers are made of a connective tissue which covers the muscular middle layer of smooth muscle, and elastic fibers.These tissues provide a smooth path for our blood to flow through.rteries carry blood which is full of oxygen away from the heart.
