Human Reproduction by Pepe Calvo

  1. 1. HUMAN REPRODUCTION By Javier Díaz, Guillermo García and Pepe Calvo February 2012
  2. 2. REPRODUCTION <ul><li>Reproduction is a life process that lets living things create other living things that are similar to them. </li></ul><ul><li>Primary sexual features : </li></ul><ul><li>The male and female </li></ul><ul><li>reproductive cells are </li></ul><ul><li>made in the male and </li></ul><ul><li>female reproductive </li></ul><ul><li>systems. </li></ul>
  3. 3. Secondary sexual features
  4. 4. Reproductive cells <ul><li>Reproductive cells or sex cells are responsable for carrying out the function of reproduction . </li></ul><ul><ul><li>Ovules. They are the female reproductive cells. An ovule matures every month since puberty. </li></ul></ul><ul><ul><li>Sperm. They are the male reproductive cells. They are small. They are constantly produced since puberty. </li></ul></ul>
  5. 5. REPROUCTIVE SYSTEMS <ul><li>Female reproductive system </li></ul><ul><ul><li>Ovaries. They produce ovules. </li></ul></ul><ul><ul><li>Uterus. A foetus develops </li></ul></ul><ul><ul><li>inside it. </li></ul></ul><ul><ul><li>Fallopian tubes. They connect the </li></ul></ul><ul><ul><li>ovaries to the uterus. The ovule </li></ul></ul><ul><ul><li>and sperm join inside it during </li></ul></ul><ul><ul><li>fertilisation. </li></ul></ul><ul><ul><li>Vagina. It is the canal that </li></ul></ul><ul><ul><li>connects the uterus to the </li></ul></ul><ul><ul><li>outside of the body. </li></ul></ul><ul><ul><li>Vulva. It is the outer part </li></ul></ul><ul><ul><ul><li>of the female reproductive </li></ul></ul></ul><ul><ul><ul><li>system </li></ul></ul></ul>
  6. 6. Male reproductive system <ul><ul><li>Testicles. They produce sperm. </li></ul></ul><ul><ul><li>Vas deferens. They are two thin tubes that take the sperm from the testicles to the urethra. </li></ul></ul><ul><ul><li>Urethra. It is the tube that takes urine or sperm outside the body. </li></ul></ul><ul><ul><li>Seminal vesicles and prostate. They are glands that produce seminal fluid and send it to the urethra. </li></ul></ul><ul><ul><li>Penis. It is outside the male reproductive system. </li></ul></ul>
  7. 7. Fertilisation <ul><li>Fertilisation is the union of a sperm and an ovule in one of the Fallopian tubes. Menstruation occurs if the ovule is not fertilised. </li></ul>
  8. 8. PREGNANCY AND BIRTH <ul><li>The development of an embryo </li></ul><ul><li>Pregnancy lasts about nine months and ends in a birth. </li></ul><ul><ul><li>The placenta. It takes nutrients </li></ul></ul><ul><ul><li>and oxygen from the mother´s </li></ul></ul><ul><ul><li>blood and gives it to the baby </li></ul></ul><ul><ul><li>The umbilical cord. Connects </li></ul></ul><ul><ul><li>the embryo to the placenta. </li></ul></ul><ul><ul><li>The amniotic sac. It is a </li></ul></ul><ul><ul><li>membrane filled with fluid </li></ul></ul><ul><ul><li>that protects the embryo. </li></ul></ul>
  9. 9. The development of a foetus <ul><li>The embryo has all its </li></ul><ul><li>organs formed after </li></ul><ul><li>the first three months. </li></ul><ul><li>By the fifth month, the </li></ul><ul><li>mother can feel </li></ul><ul><li>the baby´s movements. </li></ul><ul><li>After nine months, the </li></ul><ul><li>baby is ready to born. </li></ul>
  10. 10. Childbirth <ul><li>Childbird is when a baby leaves its mother´s womb. </li></ul><ul><li>Childbirth takes place in three stages: </li></ul><ul><ul><li>Labour. </li></ul></ul><ul><ul><li>Birth. </li></ul></ul><ul><ul><li>Afterbirth </li></ul></ul>
