Female Reproductive System

The female reproductive system is located in the pelvic region. It supports ovulation, fertilisation, pregnancy, childbirth, and lactation through a coordinated set of organs and glands.

Ovaries

Ovaries are the primary sex organs of the female reproductive system, responsible for producing eggs and secreting hormones.

Feature Detail
Number A pair — one on each side of the lower abdomen
Size 2–4 cm in length
Location Pelvic cavity; connected to pelvic wall and uterus by ligaments
Outer Cover Germinal epithelium → encloses the ovarian stroma
Stroma Zones Peripheral Cortex (contains follicles) + Inner Medulla (blood vessels, nerves)
Hormones Produced Estrogen and Progesterone (steroid/ovarian hormones)
 
Functions of the Ovaries
  • Produce female gametes (ova/ovum) through the process of oogenesis
  • Secrete steroid hormones - estrogen (secondary sexual characteristics) and progesterone (supports pregnancy)

Fallopian Tubes (Oviducts)

Each fallopian tube extends from the periphery of the ovary to the uterus, transporting the ovum and hosting fertilisation.

Part Location Key Feature Function
Infundibulum Closest to ovary Funnel-shaped; finger-like fimbriae at edges Collects the ovum after ovulation
Ampulla Middle section Wider, curved Site of Fertilisation
Isthmus Closest to uterus Narrow lumen Connects tube to uterus

Uterus

The uterus (womb) is a single, hollow, muscular, inverted pear-shaped organ located in the pelvic cavity, supported by ligaments. It houses and nourishes the developing embryo.

Three Layers of the Uterine Wall

  1. Perimetrium: External thin membranous layer - protective outer covering
  2. Myometrium: Middle thick smooth muscle layer - contracts strongly during childbirth delivery
  3. Endometrium: Inner glandular layer - undergoes cyclical changes during the menstrual cycle; site of implantation

External Genitalia (Vulva)

The external genitalia collectively form the vulva, protecting the internal organs and providing sensory functions.

Structure Description
Mons Pubis Cushion of fatty tissue covered by skin and pubic hair
Labia Majora Fleshy folds extending from mons pubis; surround the vaginal opening
Labia Minora Paired folds of tissue lying under the labia majora
Clitoris Tiny finger-like structure at the upper junction of the labia minora, above the urethral opening
Hymen Thin membrane partially covering the vaginal opening (variable presence)

Mammary Glands

Mammary glands are a characteristic feature of all female mammals. They produce milk to nourish the offspring after birth.

  • Paired structures (breasts) containing glandular tissue and variable amounts of fat
  • Each breast has15–20 mammary lobes
  • Lobes contain clusters of milk-secreting cells called alveoli
  • Alveoli store milk in their lumens (cavities)
  • Alveoli open into the mammary tubules
  • Tubules of each lobe join to form the mammary duct
  • Several ducts join to form a wider mammary ampulla
  • Ampulla connects to the lactiferous duct, which opens at the nipple

Key Points: The Female Reproductive System

  • Includes - Ovaries, Fallopian tubes, Uterus, Cervix, Vagina, External genitalia, Bartholin's glands, Mammary glands - all in the pelvic region.
  • Ovaries - outer cortex (follicles) + inner medulla; produce ova and ovarian hormones; release one ovum monthly after puberty.
  • Fallopian tube - 3 parts: Infundibulum (fimbriae collect ovum) → Ampulla (site of fertilisation) → Isthmus (connects to uterus); cilia push egg towards uterus.
  • Uterus - 3 layers: Perimetrium (outer), Myometrium (muscular), Endometrium (inner, menstrual changes); opens into vagina via cervix (birth canal).
  • Zygote implants in the endometrium; the placenta connects the embryo to the mother for nutrient and waste exchange till birth.
  • External genitalia - Mons pubis, Labia majora, Labia minora, Hymen, Clitoris. Bartholin's glands provide lubrication.
  • Mammary glands - produce milk for newborns. Puberty begins at 10–14 years in females.
