The menstrual phase, also known as the menstrual cycle or menstruation, refers to a regular physiological process that occurs in the reproductive system of females of reproductive age. It is characterized by a series of bodily changes and hormonal fluctuations that prepare the uterus for a possible pregnancy. The menstrual phase typically occurs once a month and can last anywhere from two to seven days.
During this phase, the uterus sheds its inner lining, which consists of blood, tissues, and mucus, along with unfertilized eggs. This shedding is marked by vaginal bleeding, known as menstruation or a "period." The average amount of blood lost during this phase ranges from about 20 to 60 milliliters.
The onset of the menstrual phase is triggered by a decrease in levels of estrogen and progesterone, two hormones responsible for thickening the lining of the uterus during the previous cycle. This decline in hormone levels causes the blood vessels in the uterine lining to constrict, leading to the shedding of the tissue and the subsequent release of menstrual flow.
Although the menstrual phase can be associated with varying degrees of discomfort, such as abdominal cramps and mood changes, it is a natural part of the reproductive cycle and plays a crucial role in fertility. Tracking the length and regularity of the menstrual phase can provide valuable insights into a woman's reproductive health.
The word "menstrual" is derived from the Latin word "mensis", which means "month" or "moon". This root word is also the origin of the English word "month". The term "menstrual phase" refers to a specific stage in the menstrual cycle of females, where the lining of the uterus is shed in the form of menstruation.
