Answer 1

Answer: (A), (B), (C), (D)

Blood vessels of uterus shed off

During menstrual cycle, if the ovum is not fertlilised, then, the endometrial lining (innermost lining of uterus) starts shedding off along with the blood and mucus, through the vagina. This shedding off of the endometrial lining, every month, in the absence of fertilisation is called menstruation. It lasts for 3-7 days.
