📋 3️⃣ Memory Tables
Table 1 — Artery vs Vein
| Feature | Artery | Vein |
|---|---|---|
| Wall | Thick | Thin |
| Lumen | Narrow | Wide |
| Tunica media | Thick | Thin |
| Elastic tissue | More | Less |
| Valves | Absent | Present |
Table 2 — Embryonic Vessel Derivatives
| Structure | Derivative |
|---|---|
| Third aortic arch | Common carotid artery |
| Sixth aortic arch | Pulmonary arteries |
| Vitelline veins | Portal vein |
| Left umbilical vein | Fetal oxygenated blood |
⚡ 4️⃣ Rapid Revision Points
Must Remember:
• Arteries withstand high pressure
• Veins act as blood reservoirs
• Arterioles regulate BP
• Elastic recoil maintains diastolic flow
• Endothelium prevents thrombosis
• Lymphatics drain tissue fluid
• Coarctation occurs near ductus arteriosus
• Rib notching suggests collateral circulation
• Vasa vasorum nourish large vessels
• Portal vein develops from vitelline veins
• Veins have larger irregular lumen
• Tunica media contains smooth muscle
🩺 5️⃣ Clinical Memory Hooks
Clinical Hook:
Coarctation of aorta → Upper limb hypertension + weak femoral pulse
Clinical Hook:
Varicose veins → Venous valve failure
Clinical Hook:
Atherosclerosis → Endothelial injury and arterial narrowing
Clinical Hook:
Lymphedema → Obstructed lymphatic drainage
Clinical Hook:
Hypertension → Increased arteriolar smooth muscle tone
