liver

"The liver is a large, meaty organ that sits on the right side of the belly. Weighing about 3 pounds, the liver is reddish-brown in color and feels rubbery to the touch. Normally you can't feel the liver, because it's protected by the rib cage.
The liver has two large sections, called the right and the left lobes. The gallbladder sits under the liver, along with parts of the pancreas and intestines. The liver and these organs work together to digest, absorb, and process food.
The liver's main job is to filter the blood coming from the digestive tract, before passing it to the rest of the body. The liver also detoxifies chemicals and metabolizes drugs. As it does so, the liver secretes bile that ends up back in the intestines. The liver also makes proteins important for blood clotting and other functions."

Hydatid Disease

Hydatid disease is also referred to as echinococcosis or echinococcal disease. It results from an infection due to a tapeworm of genus Echinococcus. Human echinococcosis is a zoonotic infection (i.e it is a disease of animal kingdom that sometimes can be transmitted to humans). This microscopic tapeworm is found in foxes, dogs and cats. Human cases are rare. The disease may produce cysts in the liver, lungs, brain and other organs (liver being the most common followed by lung).
