Venous ulcer is a skin ulcer caused by improper blood circulation in the legs. Venous ulcers are located on the sides of the leg, usually above the ankle and below the calf. These shallow wounds are caused by leg veins not returning blood to the heart properly.
Our skin is the largest organ in our body. It performs many functions, but the most important one is keeping organisms from entering our body. Just about every person has injured their skin at one time or another. Depending on these injuries, a scar can be left behind.
