LYMPHATIC SYSTEM Flashcards
Lymphatics develop by
6-7 weeks of GESTATION
⭐ LOWER LIMB & ABDOMINAL LYMPHATICS drain into
⭐ Upper LIMB & Head & Neck LYMPHATICS drain into
⭐ LOWER LIMB & ABDOMINAL LYMPHATICS drain into
🎯 THORACIC DUCT (via CISTERNA Chylii)
⭐ Upper LIMB & Head & Neck LYMPHATICS drain into
🎯 Right INTERNAL jugular Vein
LYMPHATIC SYSTEM starts DEVELOPING by
6-7 weeks of GESTATION
Which LYMPHATIC vessels have VALVES?
Terminal LYMPHATICS (have BICUSPID Valve)
How LYMPHATIC Vessels push their content forward?
- Lymphangions are CONTRACTILE in Nature
⬇️
Pushes the LYMPH FORWARD - Transient ⬆️ in INTERSTITIAL pressure 2° to MUSCLE CONTRACTION
- Prevention of REFLUX by VALVES
Lymphangions
Valves partition LYMPHATICS into segments
CYSTIC HYGROMA develops DUE TO:
Sequestered LYMPHATIC tissue

Cyst does NOT Communicate with NORMAL Lymphatics

Lymph gets absorbed, Clear Fluid ➕

Lymphedema
meaning
Occurs DUE TO: Inability of LYMPHATIC System to clear INTERSTITIAL FLUID COMPARTMENT
⭐ 1° LYMPHEDEMA
⭐ 2° LYMPHEDEMA
⭐ 1° LYMPHEDEMA
🎯 PRODUCTION is NORMAL ➕ DEFECTIVE LYMPHATICS
