UNIT 12: HUMAN REGULATION AND REPRODUCTION

Assignment 4: The Human Reproductive System

Starter:- Sort the keywords into two lists: one for the male system and one for the female system Male Female

Scrotum

Ovary

Sperm

Testes

Sperm duct

Uterus

Vagina

Ovum

Oviduct

Cervix

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
