reproduction

• Male reproductive system

  A) Bladder

  B) Glands

  C) Sperm duct

  D) Urethra

  E) Penis

  F) Testis

  G) Foreskin

  H) Scrotum

  
• The prostate gland produces semen which provides sperm cells with nutrients and helps them survive
• Urethra is the tube running down the middle of the penis that can carry out urine or semen. It has a ring of muscle to prevent the two fluids from mixing.
• Testes are contained inside of the scrotum and are responsible for the synthesis of sperm and testosterone
• The scrotum supports the testes outside the body to ensure that the sperm are kept alive at their optimum temperature which is slightly lower than body temperature
• The sperm duct gives the sperm a passage way to be mixed with fluids produced by the glands before travelling down the urethra for ejaculation
• The penis allows urine to be passed from the bladder and semen to pass into the vagina during sex
• Female reproductive system

  A) oviduct

  B) Ovary

  C) Uterus

  D) Cervix

  E) Bladder

  F) Urethra

  G) Vagina

  
• The oviduct, aka fallopian tubes, connects the ovary to the uterus and is lined with ciliated cells that push the released ovum down it. It is where fertilization occurs.

  A) Fallopian tubes

  B) Ovary

  C) Uterus
• The ovaries contain ova (female gamete) which will mature and develop when hormones are released.
• The uterus is a muscular bag with soft lining where a fertilized egg (zygote) will be implanted as it develops into a fetus.
• The cervix is a ring of muscle at the lower end of the uterus to keep the growing fetus in place during pregnancy
• The vagina is a muscular tube that leads to the inside of a woman's body, where the penis will be inserted and sperm deposited in
• Amniotic fluid surrounds the embryo in the amniotic sac. It protects the embryo during development by cushioning it from bumps to the mother's abdomen.

  
  

  Creates buoyancy so that the embryo does not have to support its own weight.

  
  

  The amniotic sac ruptures during labor- 'water breaking'
