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 supraorbital vein begins its course on the forehead, and it communicates with the frontal branch of the superficial temporal vein. The vein passes inferiorly, superior to the frontalis muscle and commonly joins the frontal vein at the medial angle of the orbital socket, to form the angular vein.
