Femoral hernia A hernia is caused by the protrusion of a viscus (in the case of groin hernias, an intra-abdominal organ) through a weakness in the abdominal wall. This weakness may be inherent, as in the case of inguinal, femoral and umbilical hernias. On the other hand, the weakness may be caused by previous surgical incision through the muscles and fascia in the area; this is termed an incisional hernia. Femoral hernias occur just below the inguinal ligament, when abdominal contents pass through
Composition of the human body viewed on an atomic and molecular scale as shown in this article. The estimated gross molecular contents of a typical 20-micrometre human cell is as follows: Body composition can also be expressed in terms of various types of material, such as: There are many species of bacteria and other microorganisms that live on or inside the healthy human body. In fact, 90% of the cells in (or on) a human body are microbes, by number (much less by mass or volume). Some of these symbionts are necessary for our health. Those that neither help nor harm humans are called commensal
