EQ: How do humans reproduce? Human Reproduction EQ: How do humans reproduce? I can identify and describe the basic anatomy and physiology of the human female and male reproductive systems.

Reproductive Systems Reproductive System: a collection of specialized glands, organs, and hormones used to create offspring. Puberty: the time during which hormones start the process of developing sexual characteristics. Sexual Reproduction: how the human species pass on genetic information to each generation.

Reproductive Systems Gametes: are the cells used during sexual reproduction to produce a new individual organism or zygote. Male Gamete: sperm, is a smaller, mobile cell Produced by meiosis Haploid ½ the number of chromosomes 23 chromosomes Female Gamete: egg or ovum much larger and less mobile Produced by meiosis Haploid ½ the number of chromosomes 23 chromosomes 23 23 sperm egg

Reproductive System Fertilization: union of male (sperm) and female (ovum) gametes (each with a single, haploid set of chromosomes) to produce a diploid zygote. Haploid Gametes 23 Diploid Zygote 23 46 egg 23 23 fertilization sperm

Female Reproductive System Female Reproductive System: purpose is to produce ova (eggs) and provide a place for the fetus to develop. uterus cervix rectum vagina urethra urinary bladder pubic bone ovary fallopian tube

Female Reproductive System Uterus: where the fertilized eggs develop. Cervix: the lower end of the uterus. Fallopian Tube (oviduct): leads from ovary to uterus; where the egg cell can be fertilized. Ovaries: pair of organs where eggs are produced during meiosis.

Female Reproductive System Vagina: tube leading from cervix to external female genitalia; where sperm enters. Estrogen: the female hormone responsible for developing female sexual characteristics, helping egg cells develop before leaving ovaries, and preparing uterus for pregnancy.

Female Reproductive System Female Gametes Ova: egg cells (female gametes). Names: Ovum (singular) Ova (plural) Other known name: egg(s) Produced by the process of meiosis in the ovaries. Haploid (1/2 # chromosomes) Ovulation: 1 egg per month is matured and released from ovaries, most of the time Eggs are fertilized in the fallopian tube. Fertilization

Path of Egg(Ovum) Unfertilized Ovary  Fallopian Tube (oviduct)  Uterus  Cervix  Vagina Fertilized Ovary  Fallopian Tube (oviduct) fertilization takes place  implantation in uterus

Male Reproductive System Male Reproductive System: purpose is to produce, maintain, and transport sperm to the female reproductive tract for conception.

Male Reproductive System Testes (testicles): where sperm is produced during meiosis. Testosterone: hormone responsible for sperm production and development of male sexual characteristics. Scrotum: protects testes.

Male Reproductive System Epididymis: tube through which sperm leaves the testes; where sperm matures. Vas Deferens: duct where sperm travels to urethra before exiting the body.

Male Reproductive System Urethra: tube through which semen (and urine) is expelled. Seminal Vesicles: produces nutrients that helps move sperm. Prostate: produces additional fluid to help nourish sperm.

Male Reproductive System Male Gametes Sperm Produced by the process of meiosis in the testes (1/2 the number of chromosomes) Path of sperm from the male reproductive system Testes  Epididymis  Vas deference  Seminal Vesicle  Prostate gland  Urethra

Sperm and Egg Similarities They need each other to reproduce The both contain DNA Both produced by Meiosis

Put your pencils/pens in the cup on your table Pencil Talk Put your pencils/pens in the cup on your table WITHOUT writing, discuss the relationship between the two words. (7 min) How are they similar and/or how are they different? How are their functions or locations similar or different? THEN, silently and independently write down the relationship on your Do Now paper. Ovaries / Testes Sperm / Egg Sperm / Semen Vagina / Urethra Ovulation / Ovary Fallopian tube / Uterus Vas deference / Testes Vagina / Uterus Fallopian tube / Ovary Menstrual cycle / Menstruation

Human Reproductive Card Sort – Group Work Sort the reproductive pieces (slips of paper) as either male or female parts by placing them under the correct heading. Keeping the parts separated, slide the papers off the chart. Flip your chart over to the male and female reproductive system diagrams. Use the slips of paper to label the parts of the male and female reproductive system.

Human Reproductive – Independent Work Label the male and female reproductive parts List each parts of the specific system in the chart on your hand out. Create a hashtag # to describe the function of each part. This should be short and to the point To help you remember the function

A fertilized egg undergoes several stages before it is successfully implanted. The diagram below shows these stages as the fertilized egg travels through the female reproductive system. In which of the following structures of the female human reproductive system is the blastocyst implanted during normal human development?  A. ovary B. uterus C. vagina D. amniotic sac

Sperm are created through meiosis in an area of the testes called the seminiferous tubules. Through which structure do the sperm travel to exit the testes? A. vas deferens B. seminiferous tubules C. scrotum D. epididymis

Below is a diagram of the male reproductive system Below is a diagram of the male reproductive system. Which structure is represented by D? A. scrotum B. testes C. prostate gland D. epididymis
