Male Reproductive System

Male reproductive system makes sperm

  • Urethra - tube that carries sperm through the body during ***********. Urine also passes through here when exiting the body
  • Erectile tissue - swells when filled with blood, making the penis erect
  • Testis - where sperm is made
  • Scrotal sac (scrotum) - hangs behind the penis and contains the testes
  • Vas deferens (sperm duct) - muscular tube that carries sperm from the testis towards the urethra
  • Glands - produces the liquid that is added to sperm to make *****

Female Reproductive System

Female reproductive system makes ova (eggs)

  • Ovary - the organ that produces ova and sex hormones
  • Fallopian tube (oviduct) - muscular tube that carries the ovum from the ovary to the urethra
  • Urethra (womb) - the organ where the embryo grows
  • Vagina - where sperm is deposited
  • Cervix - the neck of the uterus
  • Endometrium (lining of the uterus) - has a good blood supply for the implantation of an embryo

Female Reproductive System...(2)

  • Ova are female gametes. An ovum is produces every 28 days from one of the two ovaries
  • The ovum passes into the Fallopian tube - this is where it may meet sperm that has entered the ****** during sexual intercourse
  • If it isn't fertilised, the ovum breaks up and passes out of the ******
  • If it is fertilised, the ovum starts to divide. The new cells will travel down the Fallopian tube to the uterus (womb) and attach to the endometrium (uterus lining)
  • A fertilised ovum will develop into an embryo

At puberty, your body starts releasing sex hormones - oestragen in women and testosterone in men. These trigger off the secondary sexual characteristics:

Oestragen in women causes:

  • Extra hair on underarms and pubic area
  • Hips to widen
  • Development of breasts
  • Ovum release and the start of periods

Testosterone in men causes...

  • Extra hair on face and body
  • Muscles to develop
  • Penis and testicles to enlarge
  • Sperm production
  • Deepening of voice
