Answer:
Typically, the menstrual cycle lasts about 28 days, with a cycle of repetitive changes to the uterine tissue, breasts, and vagina.
Explanation:
However, it is important to note that the length of the menstrual cycle can vary greatly from person to person, and it is not uncommon for cycles to be shorter or longer than 28 days. The menstrual cycle is controlled by hormones and begins when a girl reaches puberty, usually around the age of 12. During the menstrual cycle, the body prepares for pregnancy and, if pregnancy does not occur, the uterine lining is shed in the form of a menstrual period. The menstrual cycle is a normal and important part of a woman's reproductive health.
