One important result of lake and reservoir enrichment is increased growth of microscopic floating plants, algae, and the formation of dense mats of larger floating plants such as water hyacinths (Photos 1 and 2) and Nile cabbage.
What is percutaneous biliary drainage? Percutaneous transhepatic biliary drainage is a procedure where a small, flexible, plastic tube is placed through the skin into the liver in order to drain an obstructed bile duct system. The liver produces bile which aids digestion of fats.
There is a bile duct from the liver to the small intestine which is joined by a duct from the gallbladder and from the pancreas. This main duct is called the common bile duct. It is common to the liver, gallbladder and farther down line, to the pancreas as well. When someone refers to the bile duct, they are usually referring to the common bile duct. It's function is to allow for the transportation of bile and digestive enzymes.
