Fertlisation and Implantation

• Steps of fertilization to implantation

  A) Fertilisation

  B) Zygote

  C) Morula

  D) Blastocyst

  E) Implantation

  
• the process that follows fertilisation is MITOSIS
• Vein and artery in placenta:

  • VEIN carries oxygenated blood with nutrients
  • ARTERY carries deoxygenated blood with wastes
• What is the outermost layer in the embryo?

  Chorion
• What embryonic layer develops outgrowths that penetrates the endometrium?

  Chorion
• Which embryonic layer increases attachment surface area?

  Chorion
• The chorion contains capillary network so that mother's blood and embryo's blood never mix
• Which embryonic layer is a temporary organ?

  Placenta
• Which embryonic layer secretes progesterone?

  Placenta
• Foetal waste is removed via placenta to mother's blood
• Which embryonic layer provides a barrier to prevent diseases?

  Placenta
• Label this diagram

  A) LH

  B) Estrogens

  C) FSH

  D) Progesterone

  
• Where does fertilisation take place?

  Fallopian tubes
• The process that allows a zygote to grow and develop?

  Mitosis
• Name the hollow ball of cells produced during embryonic development.

  Blastocyst
• Name the solid ball of cells produced during embryonic development.

  Morula
• Where does implantation occur?

  Endometrium
• What grows in order to attach the blastocyst to the endometrium?

  chorionic villi
