1 Notes: Reproductive system

2 Male Diagram OrganFunction A Prostate Gland Helps control flow of urine and produces proteins that make up part of semen A B C D E A F G H- -

3 Male Diagram OrganFunction B Ejaculatory Duct/Urethra Hollow tube where sperm and urine flow A B C D E A F G H- -

4 Male Diagram OrganFunction C Vas Deferens Tube that carries sperm from the testes A B C D E A F G H- -

5 Male Diagram OrganFunction DEpididymis Sperm are stored and mature here (interphase!) A B C D E A F G H- -

6 Male Diagram OrganFunction E Testis (plural: testes) Produces sperm and male hormones A B C D E A F G H- -

7 Male Diagram OrganFunction FScrotum Sac of skin surrounding both testes, regulates temperature so sperm don't overheat A B C D E A F G H- -

8 Male Diagram OrganFunction GPenis Tube like organ that protects the urethra (from which urine and semen exit) A B C D E A F G H- -

9 Male Diagram OrganFunction HBladder Temporary storage of urine from the kidneys A B C D E A F G H- -

10 Female Diagram OrganFunction 1OviductsConnects the ovary with the uterus A 1 2 3 4 5 6 7

11 Female Diagram OrganFunction 2Ovaries Produces eggs (only while the female is still inside her mother) A 1 2 3 4 5 6 7

12 Female Diagram OrganFunction 3Follicle Cavity where immature eggs are stored. When a follicle bursts, an egg is released. A 1 2 3 4 5 6 7

13 Female Diagram OrganFunction 4Endometrium Lining of the uterus, cushions fertilized egg, shed during menstruation A 1 2 3 4 5 6 7

14 Female Diagram OrganFunction 5Cervix Guides menstrual blood out of vagina, guides sperm up to uterus. During birth it dilates to about 4 inches. A 1 2 3 4 5 6 7

15 Female Diagram OrganFunction 6Vagina Pathway by which a baby leaves the mother's body A 1 2 3 4 5 6 7

16 Female Diagram OrganFunction 7UterusEmbryo develops here A 1 2 3 4 5 6 7

17 Stages of Fertilization Little Known Fact: Women are born with approximately 1 - 2 million immature eggs. Throughout her life, only about 40,000 survive and of those immature eggs, only about 400 will mature to be good enough candidates for fertilization Of the 400 eggs, one is lost each time a woman has a menstrual cycle. Quick math: 400 eggs = 400 periods (12/year for roughly 35 years) When eggs run out, no more periods = menopause

18 A. Egg is released from the ovary, otherwise known as ovulation or an ovulated egg. A. Ovulated egg released B. Fertilization C. Zygote D.D. E. F. Blastocyst implanting

19 B. Fertilization (sperm meeting the egg) occurs far down in the oviduct, NOT in the uterus! Sperm travel against gravity and swim about 18 cm Only about 100 sperm actually make it to the egg, but only 1 sperm can burrow inside the egg and fertilize it. A. Ovulated egg released B. Fertilization C. Zygote D.D. E. F. Blastocyst implanting

20 C. A zygote (fertilized egg) forms, otherwise known as day 0. A. Ovulated egg released B. Fertilization C. Zygote D.D. E. F. Blastocyst implanting

21 D. At the start of day 2, mitosis splits the zygote into 2 cells. A. Ovulated egg released B. Fertilization C. Zygote D.D. E. F. Blastocyst implanting

22 E. The fertilized egg travels farther down the oviduct during days 2-4, all the while mitosis is occurring at a rapid rate. A. Ovulated egg released B. Fertilization C. Zygote D.D. E. F. Blastocyst implanting

23 F. By day 7, the fertilized egg, now called a blastocyst (ball of cells) implants into the endometrium of the uterus and continues to grow for 9 months. When a fertilized egg does not implant itself into the uterus, the uterine lining is shed (menstruation) A. Ovulated egg released B. Fertilization C. Zygote D.D. E. F. Blastocyst implanting
