Do Now

1. Do Now Today, we’re beginning our unit on the reproductive system. Sometimes we’ll have conversations that may be kind of uncomfortable. As a class, we will be creating a list of class “norms” - a list of how we want to behave and interact with each other during this unit. Write 1 appropriate behavior for the class, and 1 inappropriate behavior.

3. Announcement • If you have tests to make up, you may come during your LUNCH period today

4. Format of Today’s Class • You are only to write down information about the boxes in PINK throughout the lecture • All other information will be provided for you later

5. Section 38.1 Summary – pages 995-1004 Human Female Anatomy • The main functions of the female reproductive system are to produce eggs, which are the female sex cells, to receive sperm, and to provide an environment in which a fertilized egg can develop.

6. Female Reproductive System 5 Basic Parts L L L L X X X X S S S S

7. Female Reproductive System - Ovary • Ovary • Stores and releases eggs • There are two ovaries • Female get a certain amount of eggs stored in the ovaries since birth! • There are about 3,000 eggs!!! L L L L X X X X S S S S

8. Female Reproductive System – Fallopian Tube • 2. Fallopian tube • Pathway for eggs to travel from the ovaries  uterus • Fertilization takes place here • Fertilization – joining of male sperm and female egg to make baby L L L L X X X X S S S S

9. Female Reproductive System - Uterus • 3. Uterus • Place where the fertilized egg can divide and grow into a baby • A.K.A. - womb • The blood that females menstruate is from the endometrial lining – the lining of the uterus. L L L L X X X X S S S S

11. Female Reproductive System - Cervix • 4. Cervix • The “doorway” to the uterus (located at the bottom of the uterus) • Made of strong muscles that the baby passes through during delivery L L L L X X X X S S S S

12. Female Reproductive System - Vagina • 5. Vagina • Muscular path that leads from the uterus to the outside • Menstruation comes out through here • Babies come out through here L L L L X X X X S S S S

14. Section 38.1 Summary – pages 995-1004 Egg Formation Sex Cell Production Oogonium Egg production Primary oocyte (2n) Note: No need to write this – this will be on your worksheet First meiotic division Secondary oocyte (n) First polar body (degenerates) Release into oviduct Secondary oocyte formation Sperm Second meiotic division Second polar body (degenerates) Zygote

15. Section 38.1 Summary – pages 995-1004 Oviduct How eggs are released Uterus • The process of the egg rupturing through the ovary wall and moving into the oviduct is called ovulation. Egg released Ovary Follicle ruptures Corpus luteum Vagina Egg Follicle

16. Section 38.1 Summary – pages 995-1004 Oviduct How eggs are released Uterus • A total of about 400 eggs are ovulated during the reproductive life of a female. Egg released Ovary Follicle ruptures Corpus luteum Vagina Egg • Fertilization, if it takes place, usually occurs in the oviduct. Follicle

17. Activity • Take a worksheet called “Female Reproductive System” • Try your best to fill in slots a-f on the diagram (if you are unsure, write it in pencil) • Take 3 minutes • We will review in a moment
