Report. The troposphere is the lowest layer of Earth's atmosphere and site of all weather on Earth. The troposphere is bonded on the top by a layer of air called the tropopause, which separates the troposphere from the stratosphere, and on bottom by the surface of the Earth.eport.

The bile duct is a tube that transports bile from the liver to the small intestine. The gallbladder is attached to the bile duct by a small tube called the cystic duct. Bile is collected in the gallbladder between meals and empties into the bile duct through the cystic duct during a meal.
Bile enters the duodenum when dietary fats are present. If any bile remains after the fat has been digested, it is taken back up by the gallbladder. The gallbladder is a small sac-shaped organ that stores and concentrates bile.The common bile duct is a common duct that carries bile from the liver and the gallbladder to the duodenum. If this duct is blocked, it can cause the yellowish-colored bile to back up and enter the bloodstream.This can lead to a yellowing of the skin and the whites of the eyes, known as jaundice.ile is produced by the liver and stored in the gallbladder. In this lesson, you will learn about bile and its role in the breakdown of dietary fats. You will also learn how the hormones secretin and cholecystokinin help regulate these organs.
