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.

Correct Answer is C
Explanation
A. To ensure that the uterus is securely connected to the supporting ligaments: This is not the primary function of the middle layer (myometrium); rather, the supporting ligaments provide stability to the uterus.
B. To allow the uterus to shed tissue during menstruation: This is primarily the function of the endometrium, the inner layer of the uterine wall.
C. To allow the uterus to contract during childbirth to expel the fetus: The middle layer, known as the myometrium, is composed of smooth muscle that contracts during labor to help expel the fetus.
D. To provide the uterus with adequate space to grow a fetus: While the uterine structure allows for fetal growth, the myometrium’s primary role is in contractions rather than providing space.
