# Reviewer in Science for 3rd Quarter **1. Thymosin:** - A hormone produced by the thymus gland. - Enables the body to produce antibodies. **2. Growth Hormone:** - Responsible for body growth and development. **3. Pituitary Gland:** - Considered the "master gland" of the endocrine system. **4. Scrotum:** - Protects male testicles. - Maintains a slightly lower temperature than the rest of the body to help sperm production. - Keeping the temperature too high is not advisable as it will cause low sperm production and motility. **5. Testes:** - Need to be located outside the body in the scrotum to develop at a temperature lower than body temperature. **6. Vas Deferens:** - An ejaculatory duct. - Carries matured sperm from epididymis to the urethra. **7. Fallopian Tubes:** - Critical for fertilization. - Serve as the site where fertilization typically occurs. **8. Progesterone Levels:** - If progesterone levels drop drastically after ovulation, the uterine lining sheds, leading to menstruation. **9. Fallopian Tube/Oviduct:** - Transports matured egg cells from the ovaries to the uterus. **10. Estrogen Hormone:** - Stimulates ovulation. - Thickens the endometrial lining. **11. Endometrial Lining:** - Sheds during menstruation due to a decrease in estrogen and progesterone levels. **12. Menstrual Cycle:** - A recurring process in the female reproductive system. - Prepares the body for possible pregnancy. - Typically lasts for 28 days. **13. Sympathetic Nervous System:** - Prepares the body for a "fight or flight" response. - Releases adrenaline and increases heart rate. **14. Parasympathetic Nervous System:** - Controls rest and digestion functions. **15. Central Nervous System:** - Includes brain and spinal cord. **16. Brain:** - The control center of the nervous system. **17. DNA Function:** - Stores genetic information in the cell. **18. Uracil:** - A nitrogenous base not found in DNA. **PISA Item:** - Carefully read, understand, and analyze the following article or scenario. **Scenarios:** 1. Vasectomy 2. PCOS 3. Puberty 4. Phytoestrogen 5. Prosthesis 6. Ebola Virus **Good Luck!**
