What are we learning today? Benchmark Objectives SC.912.L.16.13 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. I will identify and describe the basic anatomy and physiology of the male human reproductive system. seminal vesicle prostate gland vas deferens urethra epididymis scrotum penis testes. Science Lab: Learn About Reproduction http://www.thesciencelab.co.uk/biology/middle/7breproduction/sci_repro.swf

What is the main function of the male reproductive system? To produce gametes (sperm) by meiosis To deliver sperm To produce male sex hormones To the Teacher: Ask students to respond to the question posed in the title of the slide. Assess their prior knowledge. If needed, instruct students to listen to short video segment about the functions of the male reproductive system. Engage them in a discussion about what structures of the male reproductive system accomplish these function.

As they name the structures, ask them to explain what their function is. Assess their prior knowledge. If needed, instruct students to listen to short video segment about the anatomy of the male reproductive system. Engage them in a discussion about what structures of the male reproductive system accomplish these function.

Do Now Sequence the path that sperm follow in leaving the human body. _5__ urethra and penis _1__ testes _3__ vas deferens _4__ prostate gland and seminal vesicle _2__ epididymis Explain the function of at least three of these structures Answer the following questions in your science notebooks.

What are we learning today? Benchmark Objectives SC.912.L.16.13 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. I will identify and describe the basic anatomy and physiology of the female human reproductive system. ovaries fallopian tubes uterus cervix vagina

What is the essential question? Which male and female reproductive organs are similar to one another in function? Male Female testes ovaries Vas deferens/urethra fallopian tubes penis vagina 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.

What is the main function of the female reproductive system? To produce gametes (eggs) by meiosis To accept male gametes (sperm) To nourish and develop offspring To produce female sex hormones To the Teacher: Ask students to respond to the question posed in the title of the slide. Assess their prior knowledge. If needed, instruct students to listen to short video segment about the functions of the female reproductive system. Engage them in a discussion about what structures of the female reproductive system accomplish these functions.

If needed, instruct students to listen to short video segment about the functions of the female reproductive system. Engage them in a discussion about what structures of the female reproductive system accomplish these function.

Do Now Identify the following structures of the male and female reproductive system. Can you think of any structures that have the same function in both systems? _3_testes _1_prostate _4_penis __6_ovum _10vagina _7_ovary _8_uterus _2_vas deferens _9_cervix _5_fallopian tube To the Teacher: Hand out the students It Takes Two worksheet (Bell Ringer) found in Day 3 folder. Ask students to explain the functions of each structure.

Human Development: From Conception to Birth Research 3 Bio EOC Reproductive System Human Development: From Conception to Birth

What are we learning today? Benchmark Objectives SC.912.L.16.13 …Describe the process of human development from fertilization to birth and major changes that occur in each trimester of pregnancy. I will describe the process of human development from the zygotic stage to the end of the third trimester and birth.

Occurs in upper third of Fallopian tube What is fertilization? Fertilization is the union of a sperm cell and an egg cell to form a zygote. Occurs in upper third of Fallopian tube Only 1 sperm can fertilize an egg To the Teacher:

What cellular processes make it all happen? Growth or the increase in the number of cells. Development or the arrangement of the cells into specific organs. Differentiation or the specialization of cells to perform specific tasks and functions. To the Teacher: Use the frog diagram to explain cellular processes.

What is implantation? Zygote divides several times to form a hollow ball of cells called a morula. More cellular divisions result in a blastocyst, a ball of cells with a large fluid cavity. Blastocyst burrows into the lining of the uterus during implantation. Describe the process of fertilization and implantation?

What happens after implantation? Implanted blastocyst gradually sorts itself into three layers forming a gastrula. All the organs and tissues of the embryo will be formed from these three layers by cell differentiation.

What is neurulation? Neurulation is the development of the nervous system. Neural folds create neural tube. One end of the neural tube will develop into the brain, the other end develops into the spinal cord.

What are some important extraembryonic structures? Placenta is the structure through which the mother nourishes the embryo Umbilical cord contains arteries and veins that carry blood between the embryo and the placenta C Amniotic sac is a membrane that surrounds the embryo Amniotic fluid keeps cushions the embryo from injury and keeps it moist

What are the major milestones of the first trimester? All organ systems begin to form (cell differentiation) Nervous system begins forming Heart begins beating Embryo begins to move Ears, eyelids, and teeth buds are formed

What are the major milestones of the second trimester? Mostly growth Fetal skeleton forms Mother can feel the fetus moves Fetus can now hear. Hair forms on the body

What are the major milestones of the third trimester? Fetus turn into a head-down position. Fat is deposited beneath the skin A greasy substance forms on the fetus skin. Lungs mature Fetus can see light and react to sounds.

Muscles in the vagina and cervix relax allowing them to enlarge What is birth? Takes place about 38 weeks after fertilization Muscles in the vagina and cervix relax allowing them to enlarge Uterine contractions force fetus through birth canal Once umbilical cord is cut, baby functions independently
