reproductive parts

Male reproductive system PARTS

7 main parts

• Penis

• Sperm duct

• Urethra

• Bladder

• Testes

• Scrotum

• Glands

(Foreskin)

Sperm duct

Transports sperms from testes

To be combined w/ semen from gland along the way

Before being:

Passed into urethra for ejaculation

(male)

Prostate glands

Produce liquid, called semen, containing nutrients (sperm cells).

(male)

Urethra

Tube that runs down the center of the entire penis.

Transport semen and urine to outside the body during ejaculation.

Urine: Toxic waste product to be removed

Semen: For ejaculation

(male)

How is urine/semen prevented from mixing in the urethra?

A ring of muscle in the urethra.

Scrotum

Sac (skin) supporting the testes outside the body.

WHY?

Keep sperm at a temp lower than body temperature (optimum temperature)

(male)

Penis

To deposit semen, containing sperm, into the vagina during sexual intercourse

and

passes urine out of the body from the bladder.

(male)

Testis (plural: testes)

Sperm (male gamete) and testosterone (hormone) production

Contained in scrotum (bag of skin)

(male)

Female reproductive system PARTS

7

• Fallopian tubes (oviducts)

• Ovary

• Uterus

• Endometrium

• Cervix

• Vagina

• Bladder

Fallopian tube/oviducts

The tube that the egg travels down to get to the womb.

Connects the OVARY to the UTERUS.

FERTILISATION OCCURS HERE.

(female)

Ovary (plural: ovaries)

Release the egg cells once a month

Produce female sex hormones.

(female)

Cervix

Holds the developing foetus in place during pregnancy.

Ring of muscle at the lower end of the uterus.

Closes the top of the vagina.

(female)

Uterus

Muscular bag with soft lining

Fertilised egg (ZYGOTE) IMPLANTS to develop into a FOETUS.

(female)

Endometrium

Soft lining of the uterus

EMBRYO IMPLANTS HERE

(female)

Vagina

Muscular tube

Opens to the outside of the body,

Male’s penis enters and sperm is deposited during sexual intercourse.

(female)

Testes ADAPTATIONS

Testes outside of body

Ensure sperm are kept at temperature lower than body temperature

(Optimum temperature for sperm)

Fallopian tube/oviducts ADAPTATIONS

Lined with ciliated cells to push released egg cell.

Endometrium ADAPTATIONS

Good blood supply for implantation of an embryo
