4 WHAT ARE WE LEARNING TODAY? Date: 12/14-12/15 Topic: Human Reproductive System Learning Target: Describe the basic anatomy and physiology of the human reproductive system.

5 WHAT IS THE ESSENTIAL QUESTION? How does the anatomy of the human reproductive system relate to its physiology?

6 GALLERY WALK AND POWERNOTES (15 min) 1. Using your Power Notes, view the posters in the Gallery Walk to copy in your notes. 2. Once finished, quietly return to your seat. 3. We will review these notes. 4. Work with URGENCY

7 FERTILIZATION VIDEO W6FG4

8 What should I take away from the video? (Answer Qs. on PowerNotes) Student, what is reproduction? Student, build upon previous students answer. Student, what is the result of not being able to reproduce? Student, challenge or support previous students answer.

9 Engage Student, what are the reproductive structures of humans called? Student, build upon previous students answer. Student, what is fertilization? Student, challenge or support previous students answer. Student, summarize what previous students have said about fertilization.

10 What are the main functions of the female reproductive system? (PowerNotes) The organs of the female reproductive system are specialized for three major functions: 1. To enable sperm to enter the body, to meet with the ova and create a fetus. 2. The location where a baby develops. 3. To protect the internal genital organs from infectious organisms.

11 Basic Anatomy of Female Reproductive System ovaries fallopian tubes uterus cervix vagina

12 HOW DOES THE OVA TRAVEL OUT OF THE BODY? 1) The female reproductive system produces ova, a female reproductive cell, or gamete in the ovaries. The ova (plural ovum) is produced by female gonads (sexual glands) called ovaries. All ovum are present at birth.

13 HOW DOES THE OVA TRAVEL OUT OF THE BODY? 2) The fallopian tube allows passage of the egg from the ovary to the uterus (~every 30 days). The uterus, or womb, is a major female hormone-responsive reproductive sex organ. 3) In the uterus, the ova can be fertilized by sperm, developing into a fetus during gestation. Without fertilization, the ova will exit the body through menstruation (shedding of the uterine lining) LEFT HAND SIDE OF POWER NOTES!!!!

14 HOW DOES THE OVA TRAVEL OUT OF THE BODY? 4) The cervix allows sperm and menstrual fluid to connect the fallopian tubes and uterus to the vagina. The cervix is the lower, narrow portion of the uterus where it joins with the top end of the vagina. 5) The vagina is the location where sexual intercourse and childbirth occurs. The vagina is a hollow muscular organ that joins the cervix (the lower part of uterus) to the outside of the body. The vaginal walls are lined in a mucus membrane for protection and to keep it moist.

15 What are the main functions of the male reproductive system? (Powernotes) The organs of the male reproductive system are specialized for three major functions: 1. To produce, maintain and transport sperm (the male reproductive cells) and protective fluid (semen) 2. To discharge sperm within the female reproductive tract. 3. To produce and secrete male sex hormones

16 Basic Anatomy of Male Reproductive System testes scrotum epididymis vas deferens seminal vesicle prostate gland urethra penis

17 HOW DOES THE SPERM TRAVEL OUT OF THE BODY? 2) The epididymis acts as a maturation and storage place for sperm before they pass into the vas deferens. Epididymis: mass of tightly coiled tubes cupped against the testicles. Vas deferens (sperm duct): thin tube that starts from the epididymis to the pelvic cavity.

18 HOW DOES THE SPERM TRAVEL OUT OF THE BODY? 3) Seminal vesicles produce a sticky, yellowish fluid that provides sperm with cells energy. sac-like structures attached to the vas deferens at one side of the bladder. 4) The urethra assists in the removal of fluids from the body. tube that travels through the penis, and carries semen as well as urine.

19 HOW DOES THE SPERM TRAVEL OUT OF THE BODY? 5) The prostate gland is responsible for the production of semen. The prostate gland surrounds the ejaculatory ducts at the base of the urethra, below the bladder. Semen: a liquid mixture of sperm cells, prostate fluid and seminal fluid. 6) The penis is the male sex organ, releasing the sperm

20 Higher Order Thinking Which male and female reproductive organs are similar to one another in function? (homologous) testes epididymis scrotum Male vas deferens seminal vesicle prostate gland Urethra Penis sperm ovaries Female fallopian tubes uterus cervix vagina ovum Urethra

21 Similarities: Student, what similarities are there between the male and female reproductive systems? Student, build upon previous students answer. Student, challenge or support previous students answer. Student, combine what your previous classmates mentioned

22 Similarities The testes and ovaries both produce gametes and sex hormones. The vas deferens and fallopian tubes both carry gametes away from their production areas. The penis and vagina are both structures that assist with the delivery of sperm to an awaiting egg. The uterus and urethra
