Well, darling, the cardiovascular system is the one you're looking for. It's the highway system of the body, with arteries carrying oxygen-rich blood away from the heart and veins bringing oxygen-poor blood back.

You might want to research DVT (Deep Vein Thrombosis). It's a condition where there is a blood clot in a deep vein, and is generally diagnosed in the legs. If your veins have any of these symptoms, see your doctor immediately:

-painful legs,located to one area

-swollen areas

-discoloration around the vein

-veins seem swollen or engorged

With any issue like this, its best to consult your PCP to figure it out. If its a clot, it needs immediate attention. Good Luck!

The elastic arteries are huge and allow for large amounts of blood to go through them. They need elastic fibers so they can stretch and return to their original state--basically they want to make it easy for large amounts of blood to pass through. Muscular arteries are responsible for getting blood to various locations, so they contract and dilate according to the immediate needs of the tissue they are supplying.
