Reproductive Systems

1. Dilation

   1. The longest part of labor. The cervix dilates up to 10cm and thins out, then the water brakes.

2. Expulsion stage

   1. Infant comes out through the cervix, the the vagina and out of the body.

3. Placental stage

   1. Delivery of the placenta, you continue having contractions so the placenta can be realesed from the uterine lining

1. Seminiferous tubule

2. Rete testes

3. Epididymis

4. Vas defers

5. Ejaculatory duct

6. Urethra

When the vas deferent are cauterized by making a small incision inside the scrotum.

ovaries and testies

the union of ovum and sperm

Fallopian tube/ oviduct/ uterine tube

sperm producing

testosterone producing

white fibrous connective tissue that protects each testical

seminiferous tubules

interstitial cells

inside seminiferous tuble

• Highly coiled

• 6m or 20 in long

• Storage site for immature sperm to develop and mature

• Spermatid mature in 20 days

• Wall of the epididymis contract when a male is stimulated to expel sperm

• The muscle contraction is called peristalsis

• located at the base of bladder

• produce 60% of semen

• Thick, yellow secretion

• Rich in fructose, vitamin c, prostaglandins

• Size and shape of chestnut

• Below urinary bladder

• Secrets the milk fluid that helps activate sperm

• Pea sized

• Secrets clear and thick mucus that drains the urethra

• It purpose is to cleanse the urethra from acidic urine and lubricate during intercourse

fuel the sperm

7.2-7.6

seminalplasmin

relaxin

enzymes that enhance sperm mobility

2ml-5ml of sperm is released

begins and puberty and continues through life

4 sperm cells w 23 chromosomes

sperm steam cell

sperm

ovum

testosterone

estrogen

interstitial cells

1. Deepening of voice

2. Increased hair growth

3. Enlargement of skeletal muscles

4. Heaviness of skeletal muscles due to bone thickening

eggs or ova

estrogen or progesterone

when the egg is matured and gets ejected from the ovary

ovulation

mature the ovum

reputed follicle with yellow body that degenerates after ovulation

progesterone

fallopian (uterine) tube/ oviduct

1. Endometrium

   1. Sheds during menstruation

2. Myometrium

   1. Contracts during child birth or menstruation

3. Perimetrium

   1. Outer layer

menopause

female stem cell

1 ovum and 3 polar bodies

(only the OVUM can be fertilized)

1. Menstral phase

2. Proliferate phase

3. Secretory phase

• Enlargement of organs (Fallopian tubes, uterus, vagina and external glands)

• Development of breast

• Pubic + armpit hair

• Fat deposits in hips and breast

• Widening and lightening of pelvis

• Start of menstrual cycle

helps mention pregnancy and prepare breast for mil production

Found in men and women (only stimulated by female hormones)

Modified sweat glands

Each gland consists of 15 to 25 lobes

1. Zygote

2. Early clevage

3. Morula.

4. Early blastocyte

5. Late blastocysts

Hallow ball that releases hCG (hormone) which tells the corpus luteum to release hormones. This hormone is what the pregnancy test looks for

gives rise to nervous system and epidermis of skin

mucosal and associated glands

everything else

high estrogen levels in the last week of pregnancy makes the myometrium from oxytocin which cause weak and irregular contractions (false contractions)

placenta

powerful frequent contraction

forces the fetus to move into the mother pelvis due to stronger contractions
