Female Reproductive Organs

runs from Cervix to exterior

lies between bladder and rectum

inner mucosa lined with epiththal cells

middle layer of muscle

EPITHITHAL CELLS contain Glycogen

Resistant to sperm and microorganisms because of acidic pH

Mon Pubis- Fat containing mound covered in hair during puberty

Labia Majora- Two folds of skin containing fat, protect Labia Minora

Labia Minora- produce sebum and lubricate the vagina.

Muscular, thick hollow organ

UTERINE WALL- Outer layer PERIMETRIUM

Thick middle layer of smooth muscle MYOMETRIUM

Inner mucous membrane ENDOMETRIUM

Uterine wall shed during menstrual cycle

Fertilised egg inbeds into uterus to prevent menstrual bleed.

Lie close to the ovaries, fringed with FIMBRAE

Transport ovulated oocyte from ovary to uterus

Fertilisation can occur

The AMPULLA is the main site of fertilsation

Around ovulation frimbrae move over surface and CILIA create currents in fluid

draws oocyte from PERITORIAL cavity into fallopian tube

Inner surface lined with secretory and cilated cells that nourish the oocyte with fluid

Beat towards uterus and aid transport of eggs down Fallopian tubes

Composed of mainly GRANULOSA CELLS, THECA CAPILLARIES and FIBROBLASTS

Synthesiszes and secretes steroid hormones which are necessary for implantation and maintanance of the ZYGOTE

If fertilisation occurs steroid hormones are secreted.

Produce Ova, Secret sex hormones (Oestrogen and Progesterone)

Level of hormones control menstrual bleed

Scarred wrinkled appearance

held by ovarian ligaments

covered by Epithitial cells

Ovarian follicles lie beneath epithitial

each follicle contains an oocyte

Medulla contains blood vessels and nerve fibres

Every cycle is approx 28 days long

The FOLLICULAR phase (days 1 -10) Irregular periods occur here

OVULATORY phase (days 11-14) release oocyte

LUTEAL phase (days 15-28)

Progesterone and Oestrogen levels are constant.
