Peritonitis is defined as inflammation of the peritoneum. The inflammatory response involves vasodilation, exudation of protein-rich fluid, cellular infiltration, pain and, chronically, formation of fibrous adhesion. The disease can be classified into primary and secondary cases.
In the human body, the femoral vein is a blood vessel that accompanies the femoral artery in the femoral sheath. It begins at the adductor canal (also known as Hunter's canal) and is a continuation of the popliteal vein. It ends at the inferior margin of the inguinal ligament, where it becomes the external iliac vein.
The accessory saphenous vein is linked to the greater saphenous vein, which runs parallel to it, and is located in the leg and thigh. The greater saphenous vein is a large superficial (near the skinâs surface) vein that originates where the foot's dorsal venous arch merges with the big toe's dorsal vein. It travels up the leg's medial side (closer to the middle) after passing anteriorly to the medial malleolus, a bony projection on the inside of each ankle.
