An informational pamphlet in a health clinic describes an interaction between body systems.

the uterus is aided by the peristaltic
contractions of the smooth tissues of the
uterine tube's walls

Which statement identifies the body systems that are directly involved in the interaction
described and explains how they accomplish the interaction?
00
A The nervous system produces hormones that stimulate the ovum, and the circulatory
system moves the ovum into the uterine tube.
9
B The circulatory system supplies the uterine wall with oxygenated blood, and the
immune system prevents damage to the ovum. -
C The reproductive system produces the ovum, and the muscular system causes the
migration of the ovum by peristaltic contractions.
10
D The excretory system expels the ovum from the ovary, and the nervous system causes
the contractions of the smooth tissues of the uterine wall.
