What causes menstrual flow? Fill in the blank and separate each word with a comma in the
answer box.
When the corpus blank
ceases to function, concentrations of blank
and blank
rapidly blank
and in response, blood vessels in the endometrium
constrict. This reduces the supply of oxygen and nutrients to the thickened blank
and these lining tissues soon disintegrate and slough off. At the same
time, blood leaves blank
capillaries, creating a blank
of blood and cellular
debris that passes through the vagina as menstrual flow.
