Step-by-step explanation:
Based on the information provided in the diagram, here's a summary of the graph and the different stages of the menstrual cycle:
1. Follicular Phase: This phase begins with menstruation and is characterized by the maturation of a follicle in the ovary. Follicle-Stimulating Hormone (FSH) and estradiol levels increase during this phase.
2. Ovulation: Ovulation marks the release of a mature egg from the ovary. Luteinizing Hormone (LH) levels surge just before ovulation.
3. Luteal Phase: After ovulation, the ruptured follicle transforms into the corpus luteum, which produces progesterone. This phase prepares the uterus for potential pregnancy.
4. Menstruation: If fertilization does not occur, the corpus luteum degenerates, leading to a decrease in progesterone levels. This causes the endometrial layer (lining of the uterus) to shed, resulting in menstruation.
Regarding the changes in the endometrial layer during pregnancy, the diagram does not provide specific details. However, during pregnancy, if fertilization occurs, the fertilized egg implants itself into the thickened endometrial lining and develops into an embryo.
It's important to note that the diagram includes text mentioning "8Hisology," "Ovanan," "Follicle," "Hormones," "Endometrial Histology," "Maturing Follicle," "Body Temperature," and "Day of Menstrual Cycle." These terms are likely related to the different aspects and measurements associated with the menstrual cycle, but the diagram does not provide further context or specific explanations for each term.
