female reproductive system

Ovaries

Produces ova eggs via oogenesis secreted hormones estrogen and progesterone

Fallopian tubes

Site of fertilization transport egg from ovary to uterus

Uterus

A muscular organ where implatation and fetal development occur

The endometrium thickens each cycle to support a potential pregnancy

Cervix narrow lower portion of the uterus opening into the vagina

Produces cervical mucus that changes

during the cycle (thicker → prevents sperm,

thinner → aids sperm travel).

Vagina

Canal for interocurse birth and menstrual flow

Mons pubis

A fatty rounded are over the pubic bone that cushions and protects underlying structures covered with pubic hair after puberty

Labia majora

Outer folds of skin containing hair sweat glands and sebaceous glands protects

Labia minora

Inner thinner folds without nail. Projects opening of Th vagina

Primordial follicle

Present at birth; it contains a primary oocyte

arrested in prophase I of meiosis.

Primary follicle

The ochre enlarges the follicle cells become cuboids and start producing estrogen

Secondary follicle

Follicle grows fluid filled spaces appear estrogen secretion increases

FSH

Anterior pituitary grows follicle

Estrogen

From follicles rebuilds endometriumsiganls LH surge

LH

Anterior pituitary triggers ovulation

Progesterone

Corpus luteum maintain endometrium suppresses new cycles

hCG

From embryo of pregnancy keeps the four-us luteum active until the placenta forms

Self renewal

Stem cells divide to create more cells that retain the ability to divide

Potency

The ability of a stem cell to differentiate into specialized cells

Totipotent

A cell that can develop into any cell or tissue in an organism or a complete organism

Pluripotent

A cell that can develop into any- into several different types of cell

Ectoderm

Outer

Skin cells brain and spinal cord pigment cells

Mesoderm middle

Cardiac muscle cells skeletal muscle cells smooth muscle rec kidney cells

Endoderm inner

Lung cells thyroid cells digestive system cells

Multipotent

Unspecialized cells that can divide and differentiate into multiple specialized Cell types big in tissue repair development and protection

Oligopotent only a few

Lumphoblast mueloblast

Ova travel uterus vagina

Ovaries = produce eggs + hormones.

Uterus = implantation and fetal support.

Vagina = birth canal + menstrual exit.

Mnemonic: “Ova Travel Uterus Vagina

” → Ova
