Study Notes

  • Study notes on sex ed, grade 8

Female Reproductive System

  • Ovaries are glands that produce egg cells and estrogen.
  • Fallopian tubes transport eggs from the ovaries to the uterus; fertilization occurs here.
  • Labia are the folds of skin located on the outside of the vagina.
  • Estrogen is the primary female sex hormone.
  • Egg cells are produced in the ovaries.
  • The cervix is the opening to the uterus.
  • The vagina is the female sex organ and serves as the birth canal.
  • The uterus houses the fetus during pregnancy.
  • The clitoris is erectile tissue located between the labia.
  • Progesterone is a hormone produced by the ovaries that works with estrogen to regulate the menstrual cycle.
  • Fimbria are finger-like projections at the end of the uterine tube, guiding eggs into the fallopian tube.
  • The hymen is a membrane fold near the vaginal opening.
  • The perineum is skin located between the anus and vagina that protect the membrane.

Male Reproductive System

  • Testosterone is the primary male sex hormone.
  • The prostate gland adds chemical fluid to the semen.
  • Semen is the fluid ejaculated from the penis.
  • Testes are the organs that produce sperm.
  • The vas deferens is a tube that carries sperm from the testes.
  • Ejaculation happens when semen leaves the penis.
  • The epididymis is where sperm fully mature and are stored.
  • The urethra is the tube that carries urine from the bladder to outside the body.
  • Sperm cells are produced in the testes.
  • Seminal vesicles add a sugary (alkaline) fluid to semen.
  • Cowper's gland consists of two small glands on each side of the urethra, adding lubricating/cleaning fluid to sperm.
  • The scrotum is a sac that regulates the temperature of the testes.
  • An erection occurs when blood rushes to the penis, causing it to become engorged and hard.
  • Foreskin is a skin covering the penile glans.
  • Circumcision is the surgical removal of the foreskin.

Pregnancy and Development

  • Fertilization occurs when a sperm cell joins an egg cell.
  • The embryo describes the first two months of development in the uterus.
  • The fetus describes the last 7 months of prenatal development.
  • The placenta nourishes the fetus with the mother's blood supply.
  • The umbilical cord is a flexible cord containing blood vessels connecting the fetus to the placenta.
  • The amniotic sac is a thin sac in which the fetus develops.
  • Amniotic fluid inside the amniotic sac regulates fetal temperature and provides cushion and protection.

Labor and Delivery

  • Dilation (labor) is the first stage of labor, with contractions and the cervix thinning out and dilating.
  • Expulsion is the second stage of labor, from full dilation to the birth of the baby.
  • Placental is the third stage of labor when the placenta separates from the uterine wall, ending with the placenta's delivery.
  • Dilation is the gradual opening of the cervix in preparation for delivery.
  • Episiotomy is a surgical cut made from the vagina to the anus to ease the baby's passage.
  • Afterbirth refers to the placenta after it has been delivered.

Pregnancy Stages

  • The first trimester lasts from 0-13 weeks and is most crucial for the baby’s development; most miscarriages happen during this time.
  • The second trimester lasts from 14-26 weeks and the baby begins to move and kick.
  • The third trimester is the final stage of pregnancy.

Other Terms

  • Puberty is the period of sexual maturation, usually starting around 12 or 13.
  • Menstruation is the process where the uterine lining is shed with a small amount of blood.
  • Identical twins develop from one fertilized egg that divides.
  • Fraternal twins develop from separate fertilized eggs.
  • Fraternal twins can also occur from two separate eggs and two separate sperm cells.
  • Pubic hair is hair on genitals meant to trap debris.
  • The rectum is the final section of the large intestine that stores waste.
