Answers:Male: Scrotum, Sperm, Testes, Sperm ductFemale: Vagina, oviduct, ovary, uterus, cervix, ovum
You will be given a word… Read it out then try to describe to the
class what it is…
What you need to do:
Complete the Human Reproductive System worksheet
Work in pairs / small groups to label the male and female reproductive organs.
Assignment 4: Objectives The structure of the male and female
reproductive organs, including functions of each part.
The process of gametogenesis (production of sex cells)
Fertilisation The reproductive hormones The menstrual cycle and hormone levels at
different times of the month. Fertility treatment and IVF (including analysis
of data relating to hormones)
Today’s Lesson Objectives The structure and function of the male
and female sex organs Gametogenesis (production of gametes) Reproductive Hormones: What are they?
How do they control fertility?
The ______ reproductive
system
*Sperm duct(Vas Deferens)
* Testes
* Scrotum
* Urethra
* Penis
* Gland
* Bladder* male
The ________ reproductive system
* Uterus
* Vagina* Cervix
* Ovary
* Fallopian Tube
*female
Card Sort: Now start thinking about what each
reproductive part does. Match the word to it’s function.
Sometimes called the womb – if an egg is fertilised it will implant in the wall of the uterus and develop into a foetus
After puberty, an egg or ovum is released from here once every 28 days or so.
The opening or ‘neck’ of the uterus at the top of the vagina.
Connects the cervix to the outside of the body - sperm is deposited here by the penis during sex
The female sex cell – sometimes called an ‘egg’.
UTERUS
OVARY
CERVIX
OVUM
VAGINA
Carries the ovum from the ovary to the uterus – the egg is fertilised here.
OVIDUCT/Fallopian Tube
Endometrium : The lining of the uterus, supports an embryo after implantation
Vas Deferens (Sperm Duct): Tube which sperm travels along from the testes.Epididymis: Where the sperm are stored
After puberty, these make sperm continuously.
A sac of skin which holds the testes .SCROTUM
TESTES
The male sex cell – it is adapted to swim from the vagina to the egg.
SPERM
The ________ reproductive system
* Uterus
* Vagina* Cervix
* Ovary
* Fallopian Tube
*female
Outline the route taken from the testes by the sperm as it leaves the body
Sperm leaves the testes and travels along the sperm duct...
... which travels past/through the glands.
The glands provide the sperm cells with food so that they have energy for swimming
The sperm duct joins the urethra...
... which carries the sperm out of the body.
Ovum
Sperm cell
Membrane
Nucleus
Cytoplasm
Jelly coat
Tail...... for swimming
Sperm
How are Sex Cells produced?
How much can you remember about meiosis from unit 18?
Have a go at the following:1. What does a) Haploid and b) Diploid mean?2. Why are gametes (sex cells) Haploid?3. What are the stages of meiosis?
Gametogenesis The production of sperm and the
production of ova are both examples of meiosis.
However, the processes differ in many ways because they result in different cells being made.
The production of ova is called Oogenesis The production of sperm is called
Spermatogenesis
Oogenesis
Oogenesis:
Class Task 1: Oogenesis Fill in the following words / terms on the
diagram:
Ovulation Degenerating corpus luteumDay 14 OvumCorpus Luteum Secondary follicleOocytePrimary folliclesPrimary OocyteOogonia
Spermatogenesis:
Label the Spermatogenesis diagram with the following words:SpermatogoniaPrimary SpermatocyteSecondary SpermatocyteSertoli CellsSpermatidDeveloping Spermatozoa
