yfirborðsbláæðum

Yfirborðsbláæðum, also known as superficial veins, are a network of veins located close to the surface of the skin. They play a crucial role in the circulatory system by returning deoxygenated blood from the body's tissues back to the heart. Unlike deep veins, which are surrounded by muscles and bones, superficial veins are more visible and palpable through the skin.

These veins are an integral part of the venous system, working in conjunction with deep veins to ensure efficient blood flow. The blood in superficial veins is often a darker shade of red due to its lower oxygen content. In healthy individuals, the valves within these veins prevent blood from flowing backward, ensuring unidirectional movement towards the heart.

Conditions affecting superficial veins can include varicose veins, where the veins become enlarged and twisted, often due to weakened valves or increased pressure. Spider veins, smaller and more delicate than varicose veins, are also a common manifestation of superficial venous issues. Medical professionals often assess the health of superficial veins during physical examinations to evaluate overall circulatory health and diagnose potential problems.
