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 femoral vein runs parallel to the artery, like in first picture, on the side closest to your genitals. (So, if you're feeling on your left side, the vein is to the right of the artery; if feeling on the right side, the vein is to the left of the artery-- The first picture shows your left side only.)
