Today the class started with an attendance question and then moved on to answering the anonymous questions from yesterday. After, we learned about the female reproductive system in the forest school and then copied out the following graph from this video with these additional notes. Lastly, we had another time for submitting anonymous questions. We also compared the size of a egg and sperm on this website: https://learngendev.azurewebsites.net/content/cells/scale/ Notes... (based on a 28 day cycle) Day 1-5 = Menstrual (flow) Phase = Menstruation is caused by a decrease in estrogen and progesterone. Day 6-13 = Proliferate (follicular) Phase = Ovum (egg) develops and endometrium (uterus lining) thickens. Day 14 = Ovulation = Spike in estrogen, LH, and FSH and progesterone starts to increase. Day 15-28 = Secretory (luteal) Phase = Endometrium still thickening and progesterone increases. Estrogen = regulates menstrual cycle (ovulation and menstruation). Progesterone = maintains pregnancy. Decrease in progesterone will lead to menstruation. Luteinizing Hormone (LH) = Regulates the ovum (egg) being released. Follicle Stimulating Hormone (FSH) = Stimulates growth of the ovaries and ova. Please copy out the following notes + graph and complete the worksheet if you were not here this day! Comments are closed.
