How does the increase in the estrogen level correspond the change in thickness of the uterine lining in days 1 through 13 of the menstrual cycle? *
The uterine lining thins out.
The uterine lining thickens.
O The uterine lining sheds and then begins to thicken.
Estrogen does not affect the thickness of the uterine lining; only progesterone does

Each month most females will release an egg into their ovaries. The FSH or (follicle stimulating hormone) eggs will be begin to grow and mature inside the ovary. When the egg is ready to be released the luteinizing hormone or LH will finally reach the peak level. With the high hormone levels, the egg will burst through the follicle. This sets off a reaction to the hormone estrogen which in turn makes the uterus lining thicker. The lining sets itself up to protect the egg and nourish the egg if it is fertilzed. If the egg doesn't get fertilized, the uterine lining will decrease and shed. This is when a woman gets her menstrual cycle. So the increase in the estrogen is what makes the thickness of the uterine lining.

hope this helps
