Hernia (1/3), where the hernia contents push through a weak spot in the back wall of the inguinal canal. Inguinal hernias are the most common type of hernia in both men and women. In some selected cases, they may require surgery. There are special cases in which the hernia may contain both direct and indirect hernia simultaneously pantaloon hernia, or, though very rare, may contain simultaneous indirect hernias. Pantaloon hernia (Saddle Bag hernia) is a combined direct and indirect hernia, when the hernial sac protrudes on either side of the inferior epigastric vessels. Femoral hernias occur just below the inguinal ligament,
Composition of the human body Not all elements which are found in the human body in trace quantities play a role in life. Some of these elements are thought to be simple bystander contaminants without function (examples: caesium, titanium), while many others are thought to be active toxics, depending on amount (cadmium, mercury, radioactives). The possible utility and toxicity of a few elements at levels normally found in the body (aluminium) is debated. Functions have been proposed for trace amounts of cadmium and lead, although these are almost certainly toxic in amounts very much larger than normally found in the body. There is evidence that
