What term refers to small, widened blood vessels found on the body?

The term "spider veins" specifically refers to small, widened blood vessels that often appear on the surface of the skin, typically in a web-like or spider's web pattern. These veins are usually red, blue, or purple and are most commonly found on the legs and face. They are a type of telangiectasia, which are dilated small blood vessels near the surface of the skin.

While varicose veins are also a vascular issue, they are larger and raised, often causing more significant discomfort and are primarily associated with poor blood flow. Capillaries are the smallest blood vessels in the body but are typically not used to describe visible vascular conditions. Angiomas, on the other hand, refer to benign tumors made up of blood vessels, which can appear as red or purple spots but do not describe the small widened vessels seen in spider veins. Thus, "spider veins" is the most accurate term for what the question is describing.
