Understanding Vein Types: Superficial, Deep & Perforating

Veins return blood to the heart. Three main types:

1. Superficial veins – just under skin, visible/palpable (legs, arms).
2. Deep veins – near bones, not visible (legs, arms, abdomen).
3. Perforating veins – connect superficial to deep veins (mostly legs/arms).

Functions

• Superficial → carry blood to deep veins.
• Deep → return blood to heart.
• Perforators → shunt blood between systems.

Common Vein Disorders

• Varicose veins (superficial)
• Deep vein thrombosis (DVT)
• Pulmonary embolism (PE) – life-threatening

Seek medical attention for pain, swelling, or discoloration.
