Answer 1

Step 1: Define Menstrual Cycle.
The menstrual cycle refers to the series of changes in a woman's body that prepare it for a possible pregnancy. It lasts about 28 days but can range from 21 to 35 days. The cycle includes hormonal changes that lead to ovulation and menstruation.
Step 2: Main Steps of the Menstrual Cycle.
The menstrual cycle consists of the following phases: \begin{enumerate} \item Menstrual Phase: This phase starts with menstruation, where the uterine lining is shed. This phase typically lasts for 3-7 days. \item Follicular Phase: The follicular phase begins after menstruation and involves the development of follicles in the ovaries under the influence of FSH (Follicle Stimulating Hormone). It lasts around 10-14 days. \item Ovulation: Ovulation occurs around the middle of the cycle when a mature egg is released from the ovary into the fallopian tube. This is triggered by the surge in LH (Luteinizing Hormone). \item Luteal Phase: Following ovulation, the luteal phase begins. The ruptured follicle forms the corpus luteum, which secretes progesterone to prepare the uterus for pregnancy. If no pregnancy occurs, the corpus luteum breaks down, leading to the next menstrual cycle. \end{enumerate}
Final Answer: The menstrual cycle consists of four main phases: menstrual, follicular, ovulation, and luteal. These phases regulate hormonal changes and prepare the body for pregnancy.
