1 SC.912.L Describe the basic anatomy and physiology of the human reproductive system. Describe the process of human development from fertilization to birth and major changes that occur in each trimester of pregnancy. How does the fetus develop from fertilization to birth?

2 During fertilization, the male sperm unites with the female egg to form a zygote that develops into a fetus. In which female structure does almost all of fetal development take place? A. Ovaries B. Fallopian tubes C. Uterus D. Cervix Take 1-2 minutes to have students answer each question.

3 Following puberty, a female has a monthly cycle which includes ovulation, or the maturation of the egg cell. What structure of the female reproductive system is responsible for this process? A. Ovaries B. Fallopian tubes C. Uterus D. Cervix Answer: A Print Exit Slip questions as a separate handout if desired.

4 Interactive Journal Left side Title: Reproductive System Activity
Right side Title: SC.912.L Human Reproduction Attach the guided notes to the right side of your notebook and complete the blanks. Depending on the student levels in the class, you may opt to have students use Cornell notes instead; adjust the right side text if needed or provide copies of guided notes. Write this title on your left side page. Write this title on your right side page.

5 Human Reproduction Puberty - sexual maturity
follows release of male and female hormones production of mature gametes (sperm and eggs) Reproduction is sexual male sperm combines with the female egg to get a fetus Creates offspring with a unique genetic combination “I Do” phase begins and continues through slide 14

6 Female Reproductive System
Reproductive system – group of organs required to produce new offspring Major parts of the female reproductive system - the ovaries, fallopian tubes, uterus, cervix, and vagina

7 Female Reproductive System
Ovaries – produces egg cells, or ova, and female hormones such as estrogen and progesterone; ovulation (egg maturation) happens here Uterus – area where the fetus implants and develops when pregnancy occurs

8 Female Reproductive System
Fallopian tubes – the egg travels to the uterus in this area and may be fertilized here; problem if implantation occurs here

9 Female Reproductive System
Cervix – bottom of the uterus that opens into the vagina Vagina – the birth canal that a baby passes through as it is being born

10 Male Reproductive System
Major parts of the male reproductive system – testes, scrotum, seminal vesicle, prostate gland, vas deferens, urethra, epididymis, and penis

11 Male Reproductive System
Testes (testicles) – organs that produce sperm due to testosterone (male hormone) Scrotum – pouch that contains the testicles Epididymis – store sperm during maturation

12 Male Reproductive System
Prostate gland – produces fluid containing nourishment for sperm Seminal vesicles – secrete fluids containing sucrose for energy needed for sperm The sperm plus the fluid secretions are known as semen.

13 Male Reproductive System
Vas deferens – tube that semen travels through from the epididymis during sexual stimulation Penis – consists mostly of erectile tissue and is used for fertilization Urethra – tube found in the penis which releases both urine from the bladder and semen for reproduction

14 Male Reproductive System
Penis – consists mostly of erectile tissue and is used for fertilization Urethra – tube found in the penis which releases both urine from the bladder and semen for reproduction

15 Female Reproductive System
Label the following parts of the female reproductive system: ovary, fallopian tube, uterus, cervix, and vagina. “We Do” practice for female system – the teacher points to each structure and asks the students to identify what the part is on the diagram. The pictures for this slide and the next slide are in the attachment titled “ Reproductive System Diagrams” (if you wish to print them and have students put them in their Interactive Journals [left side page} and label them by hand as you and students answer the questions).

16 Male Reproductive System
Label the following parts of the male reproductive system: penis, scrotum, testes, seminal vesicles, epididymis, urethra, vas deferens, and prostate gland. “We Do” practice for male system – the teacher points to each structure and asks the students to identify what the part is on the diagram; use the optional diagrams mentioned in the notes on the previous slide if you wish.

17 Reproductive Systems – Your turn
Attach the Reproductive Systems chart to the left side page. Mark each part as male or female and write its function. Complete what you can independently from memory. “We Do” practice part 2 – let student complete copies of the chart that you provide. This activity would be a second left hand page if you use the diagrams, or you can have students “layer” the chart (attach sideways and fold to fit in Interactive Journal) on the same page as the pictures. Teacher knowledge: the urethra is found in males and females; testes and testicles are names for the same structure.

18 SC.912.L Describe the basic anatomy and physiology of the human reproductive system. Describe the process of human development from fertilization to birth and major changes that occur in each trimester of pregnancy. How does the fetus develop from fertilization to birth?

19 While a woman is pregnant, she will gain weight during the entire nine month period. However, the fetus does not gain weight and increase in length at the same rate throughout this time. At what point does the fetus change the most dramatically in size? A. the first week of birth B. the first trimester C. the second trimester D. the third trimester

20 One of the milestones of pregnancy is when a mother feels the fetus kicking. When does this movement first appear? A. The first trimester B. The second trimester C. The third trimester D. Immediately before birth Answer: B

21 Interactive Journal Left side Title: Trimesters Activity Right side
Title: SC.912.L Human Development Attach the reading selection titled “Pregnancy: The Three Trimesters” to the right side of your journal. Mark the text to make notes from the following slides. Provide copies of the reading selection. Let students know that information is not necessarily in exact order (reading strategy). Write this title on your left side page. Write this title on your right side page.

22 The Three Trimesters of Pregnancy
Each 40 week pregnancy is divided into 3 trimesters with a series of events that occur during fetal development and end in birth. First trimester: 0-12 weeks Second trimester: weeks Third trimester: weeks Teacher presents “I Do” part of lesson from this slide through slide 13

23 First Trimester Body structure and organ systems develop.
The zygote changes to a blastocyst and then an embryo that implants in the uterine wall. The spine, cerebral hemispheres, a beating heart, and the digestive tract form.

24 First Trimester The spine, cerebral hemispheres,
a beating heart, and the digestive tract form. Movement begins as muscles form. The reproductive system, white blood cells, and vocal cords appear.

25 Second trimester The hair and toenails grow, while eyes and ears move into correct positions. The fetus is sucking and swallowing amniotic fluid. The gender can be determined.

26 Second trimester Urination occurs and solids appear in the digestive system. Senses begin forming. Teeth, bones, and joints appear.

27 Second trimester Lanugo (body covering of fine hair) and vernix (waxy covering of skin) form. The capillaries begin to carry blood. Movement increases and is detected by the mother.

28 Third trimester Growth continues until a final weight of 6- 9 pounds and inches is reached. The brain can detect signals from senses, light and darkness, and outside sounds; synapses develop between neurons. Strong movement is felt by the mother.

29 Third trimester Body systems mature by 32 weeks except the lungs, which are complete by birth. Fat accumulates, and the vernix and lanugo shed. The fetus rotates to a “head first” position.

30 Pregnancy: The Three Trimesters
What significant developments to body structure and organ systems happen during each trimester? What changes does the mother feel as the pregnancy advances? Use this “We Do” time to discuss questions. Students can do a “think-pair-share” or you can have a question and answer discussion with the students. The goal is to make sure that students are thorough in their answers, and to correct misconceptions about the content.

31 Pregnancy: The Three Trimesters
On the left side of your journal, divide the page into 3 sections and label each with the first, second, and third trimester. Select and list 3 events for each trimester that you feel are the most significant for proper development. After students complete this activity, the teacher can have a brief discussion about the events to Check for Understanding.
