Which of the following is true about the three layers juries, and parents are concerned about the long-term of involuntary smooth muscles of the uterus?

Correct Answer: A

Rationale: The correct statement about the three layers juries, and parents are concerned about the long-term of involuntary smooth muscles of the uterus is that they are designed to provide expansion of the growing fetus. The three layers of the uterus, consisting of the perimetrium, myometrium, and endometrium, play essential roles during pregnancy. The myometrium, which is the middle layer of the uterus, contains involuntary smooth muscle fibers that contract during labor to help expel the fetus. These muscles are designed to expand and contract to accommodate the growing fetus during pregnancy and aid in the birthing process.
