Science: Repro system-female
Based on the given graph:
Topic: Menstruation Cycle
1. What is the body temperature difference of the follicular phase compared to the luteal phase?
2. Which hormone is at its peak during ovulation?
Birth control pills commonly provide excess progesterone that serves to inhibit (suppress) the actions of FSH and LH through a negative feedback loop. Given the role these hormones (FSH and LH) play, how could this feedback loop prevent a woman from becoming pregnant?
Which of these functions explains the role of hormones in the reproductive systems?
A. Influence female sex traits
B. Regulates body temperature.
C. Controls the calcium level in the blood.
D. Enables the body to produce more antibodies
4. Which of these reproductive parts explains the role of progesterone in the onset of puberty?
A. Penis
B. Uterine lining
C. Oviduct
D. Hypothalamus

Which hormones are present in largest concentration just before ovulation? During which part of the menstrual cycle is the endometrium most prepared to receive an embryo? Which hormones stimulate thickening of the endometrium? Gonadotropic hormones and ovarian hormones regulate the monthly sequence of events that take place within the ovary and uterus. The preovulatory phase begins with menstruation; the postovulatory phase begins after ovulation. Figure 50-14 Endocrine regulation of the menstrual cycle When fertilization does not occur, the menstrual cycle repeats about every 28 days. Note the changes in hormone concentrations that regulate the menstrual cycle.
