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.

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

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

FERTILIZATION VIDEO https://www.youtube.com/watch?v=_5OvgQW6FG4 1. Sexual Development – Hormones 2. Male Reproductive System a. Function – sperm development and release b. Structures - seminal vesicle, prostate gland, vas deferens, urethra, epididymis, scrotum, penis, and testes 3. Female Reproductive System a. Function – menstrual cycle b. Structures - ovaries, oviduct (fallopian tube), uterus, cervix, and vagina

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.

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.

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

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. The female reproductive system produces ova, a reproductive cell, or gamete. The ova is produced by female gonads (sexual glands) called ovaries. All of them are present at birth.

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!!!! In a woman's body the fallopian tube allows passage of the egg from the ovary to the uterus. The uterus, or womb, is a major female hormone- responsive reproductive sex organ. In the uterus, implantation happens and the fetus develops during gestation. One end, the cervix, opens into the vagina, while the other is connected to one or both fallopian tubes.

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. The cervix is the lower, narrow portion of the uterus where it joins with the top end of the vagina. The cervix has an opening to allow sperm and menstrual fluid to move through. The vagina is a sex organ with two main functions: sexual intercourse and childbirth. 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.

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

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. Coiled epididymis-increases area to hold more.* The vas deferens, also known as the sperm duct, is a thin tube approximately 43.2 centimetres long that starts from the epididymis to the pelvic cavity.

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. The vas deferens, also known as the sperm duct, is a thin tube approximately 43.2 centimetres long that starts from the epididymis to the pelvic cavity.

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 from the body. The vas deferens, also known as the sperm duct, is a thin tube approximately 43.2 centimetres long that starts from the epididymis to the pelvic cavity.

Higher Order Thinking Which male and female reproductive organs are similar to one another in function? (homologous) Male Female testes ovaries epididymis fallopian tubes scrotum uterus vas deferens cervix seminal vesicle vagina prostate gland ovum Urethra Penis sperm The reproductive systems of the male and female have some basic similarities and some specialized differences. They are the same in that most of the reproductive organs of both sexes develop from similar embryonic tissue, meaning they are homologous. Both systems have gonads that produce (sperm and egg or ovum) and sex organs. And both systems experience maturation of their reproductive organs, which become functional during puberty as a result of the gonads secreting sex hormones. Answer: 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

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

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

Neuroplasticity Session!!! Silently and Independently! End

Exit Ticket On your tablets Work silently and independently No notes allowed Work with urgency Estrogens: sex hormones that stimulate the growth of a girl's sex organs and “feminine” physical characteristics and regulate the functioning of the menstrual cycle. Androgens: sex hormones that help trigger the development of the testes and penis in male and of “manly” physical characteristics.
