Study Notes
Grade 10 Reproductive System
- The reproductive system is a set of organs and structures essential for the survival of a species. It ensures the production of offspring.
Babies and Their Story
- Students should reflect on times when they learned about a new baby.
- It is appropriate to consider questions or ideas about how babies develop in the womb
Today's Learning Objectives
- Learning the structures and functions of the female reproductive system.
- Understanding the menstrual cycle in simple terms.
- A human baby's heart starts beating 21-22 days after fertilization.
The Human Reproductive System
- The human reproductive system is a group of organs and structures that work together in the production of offspring.
Female Reproductive System
- It has four main functions:
- Producing sex hormones like estrogen and progesterone.
- Producing eggs (ova).
- Supporting and protecting a developing embryo.
- Giving birth to a baby.
Major Organs (Female Reproductive System)
-
Cervix
-
Vagina
-
Ovaries (gonads)
-
Uterine tubes (fallopian tubes)
-
Uterus
-
Gonads (ovaries/testes) are the organs that produce reproductive cells (gametes) as well as sex hormones.
External Genitalia
- Vulva: A large area from the pubic region to the rectum.
- Mons pubis/mons veneris: A hairy, padded area of fat over the pubic bone.
- Labia majora: The larger folds of skin surrounding the vagina, containing Bartholin's glands that contribute to lubrication.
- Labia minora: Smaller, hairless folds of skin encompassing the vaginal opening.
- Clitoris: A small, pea-shaped structure involved in sexual arousal in females.
- Urethral orifice: The opening for urine, located below the clitoris on the wall of the vagina. The opening of the vagina is separate from the opening of the urethra.
- Vaginal orifice: The opening into the vagina.
- Perineum: The area between the vaginal opening and anus.
- Anus: The opening for waste elimination.
Vagina
- A muscular, ridged sheath connecting the external genitalia to the uterus.
- Acts as a two-way passage during intercourse, allowing for the entry of the penis and sperm.
- Serves as the birth canal.
Cervix
- The lower portion (neck) of the uterus.
- Lined with mucus (cervical mucus) for lubrication and sperm transportation.
- The cervical mucus increases during ovulation due to estrogen.
- During pregnancy the cervical canal enlarges significantly to allow the passage of a baby during childbirth.
Uterus
- Pear-shaped muscular organ within the female reproductive tract.
- Fundus: The top part of the organ, where pregnancy occurs.
- Cervix: The bottom part that connects to the vagina, acting as a sphincter that helps keep the uterus closed.
- The uterus expands substantially during pregnancy, potentially 10-20 times its normal size.
- The uterine wall consists of a firm outer coat (myometrium), and an inner lining (endometrium) which is vascular and glandular.
- The endometrium goes through changes during the menstrual cycle, preparing the uterus for potential implantation of a fertilized egg.
Fallopian Tubes
- Also known as uterine tubes.
- Connect the ovaries to the uterus, about 8-13 cm in length.
- Fimbriae: Ends of the tubes near the ovaries, they are feathery in appearance.
- Cilia: Tiny hair-like structures lining the fallopian tubes, moving the egg through the tube.
- Fertilization typically occurs in the fallopian tubes.
Ovaries
- Also known as female gonads.
- Produce eggs (ova) throughout a woman's lifetime.
- Produce estrogen and progesterone.
The Journey of the Sperm Cell
- The journey of the sperm from the testes to the fallopian tubes before fertilization.
- 8 steps
Menstrual Cycle
- A recurring natural process in females.
- Lasts approximately 28 days on average.
- Prepares the body for pregnancies and releases an egg.
- If no pregnancy occurs the lining is shed during menstruation.
Stages of the Menstrual Cycle
- Follicular Phase: The pituitary gland releases hormones that stimulate the growth and development of follicles in the ovaries, where eggs develop.
- Ovulation Phase: The mature egg is released from the ovary.
- Luteal Phase: The empty ovarian follicle becomes the corpus luteum, producing hormones that prepare the uterus for a possible embryo or pregnancy.
Menstrual Disorders
- Dysmenorrhea: Severe pain during menstruation
- Amenorrhea: Absence of menstruation
- Oligomenorrhea: Irregular or infrequent menstruation
Learning Check Answer Key
- The menstrual cycle prepares the body for pregnancy by releasing an egg and preparing the uterus.
- If no pregnancy happens, the lining of the uterus is shed during menstruation.
The Miracle of Life
- A summary of the process
