Which structure allows bile to drain and enter the gallbladder?
Cystic duct
Common hepatic duct
Pancreatic duct
Left hepatic duct
The Correct Answer is A
A. Cystic duct: The cystic duct connects the gallbladder to the bile ducts and allows bile to flow into and out of the gallbladder.
B. Common hepatic duct: This duct carries bile from the liver but does not directly lead to the gallbladder.
C. Pancreatic duct: This duct transports digestive enzymes from the pancreas to the duodenum, not bile.
D. Left hepatic duct: This carries bile from the left side of the liver and eventually merges into the common bile duct, but it does not lead directly to the gallbladder.

A. This allows for rapid exchange of oxygen and nutrients: Capillaries have thin walls (one cell thick) to facilitate the rapid diffusion of gases (oxygen and carbon dioxide), nutrients, and waste products between blood and tissues.
B. This allows for red blood cell formation to occur: Red blood cells are formed in the bone marrow, not in capillaries.
