Study Notes

Human Reproductive System

  • Reproduction is a process by which organisms produce new organisms like themselves.
  • It ensures the transfer of genetic information from one generation to the next and the continuity of a species.
  • Heredity is the process where characteristics are passed down genetically from one generation to the next.
  • The union of an egg cell's nucleus and sperm cell's nucleus forms a fertilized egg (zygote), which develops into a new individual.
  • Egg cells carry genes from the mother and sperm cells carry genes from the father.
  • The genes from both parents are then passed on to the new individual.

Puberty in Boys and Girls

  • Puberty is a period where adolescents become capable of reproduction and experience significant physical changes.
  • In boys, hair growth in armpits, face, and penis enlargement and voice deepening occur. Testes and penis grow in size.
  • In girls, hair growth in armpits and pubic region, breast and uterus development, and hip changes occur. Voice box enlarges.

Parts of the Male Reproductive System and their Functions

  • Sperm duct: Carries sperms from the testis to the urethra.
  • Sex gland: Secretes fluid containing nutrients and enzymes for sperm energy.
  • Penis: Male reproductive organ that becomes erect for sexual intercourse.
  • Urethra: Tube that leads to the outside of the body through the penis and transports sperm..
  • Testis: Contains sperms and sex cells
  • Scrotum: Holds the testes.

Parts of the Female Reproductive System and their Functions

  • Oviduct: Muscular tube connecting the ovary to the uterus and carrying the egg.
  • Ovary: Produces eggs and female sex hormones.
  • Uterus: Pear-shaped organ with thick walls to house the growing embryo or foetus.
  • Cervix: Ring of muscle at the lower end of the uterus.
  • Vagina: Muscular tube connecting the cervix to the body's exterior

Menstrual Cycle

  • A monthly cycle involving the release of an egg from the ovary.
  • Days 1-5: Menstruation (the shedding of the uterine lining).
  • Days 6-9: The uterine lining grows thicker.
  • Days 10-15: The fertile period (when ovulation occurs, the release of an egg).
  • Days 16-28: The uterine lining remains thick to supply nutrients and oxygen to a potential embryo.

Fertilisation

  • The process in which the nucleus of a sperm cell fuses with the nucleus of an egg cell to form a fertilized egg (zygote).
  • The zygote begins to divide repeatedly to form the embryo then foetus.

Disruption of Reproductive System

  • Substance abuse: Substance abuse can cause premature babies, undeveloped organs, low birth weights and higher infection risks in babies.
  • Sexually transmitted infections (STIs) : STIs like syphilis, gonorrhea, and AIDS have serious consequences which include tiredness, weight loss, fevers and diarrhea, infertility, lung infections, brain infection and eventually death.
  • Unwanted pregnancies: Unwanted pregnancies can lead to social and financial problems.

Methods Preventing Pregnancy

  • Temporary methods: Abstinence, rhythm method, use of contraceptive pills, spermicides, use of mechanical devices (condoms, diaphragms, intra-uterine devices).
  • Permanent methods: Vasectomy, tubal ligation.

Abortion

  • Abortion is the termination of a pregnancy.
  • It has both medical and social reasons. medical-physically or mentally unable to support a child or have difficulties getting pregnant again, social-family is not financially ready, or unwanted pregnancy resulting in rape.
