Which molecule type does bile emulsify?

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.

A. Brachiocephalic artery: This artery supplies blood to the upper body, including the head, neck, and right arm, but not the lower limbs.

B. Splenic artery: The splenic artery supplies the spleen, and it has no direct role in supplying blood to the lower limb.

C. Common hepatic artery: This artery supplies the liver, not the lower limbs.

D. Femoral artery: This is the major artery supplying oxygenated blood to the lower limb, making it the correct answer.
