Transcript of The Birds and The Bees
with an egg... The ovaries are small, oval-shaped glands that are located on either side of the uterus. YOU ARE HERE Once a month,
the ovaries release one egg... meanwhile fallopian tubes are narrow ducts that
connect the ovaries to the uterus Conception (fertilization) usually occurs here in the tubes Meanwhile...
in the brain two important hormones are being released
... which in return causes a thick mucus
to be produced in the lining of the uterus these hormones (FSH&LH) do two things... they stimulate the growth of
about 15-20 eggs in the ovaries.... but only one egg in one of the ovaries become dominant and mature... this is again, the one that is released every month but more importantly, the hormones trigger an increase in ESTROGEN IN FACT!
If a woman were to have intercourse during this time, the thick mucus captures the man's sperm, nourishes it, and helps it to move towards the egg for fertilization. meanwhile...
in the body of the male the reproductive system of
a male primarily serves to produce, store and deliver sperm how so ?... lets begin... sperm and the male sex hormones are produced in the testes the interior of each testicle
consist of multiple lobules every male has a total of two testicles who produces the sperm, Androgens, and testosterone the testes are suspended in a pouch of skin called the scrotum the scrotum protects and supports the reproductive organs that are located outside the body cavity which include the testicles, epididymis, and the Vas deferen the sperm is produced in the seminiferous tubules of these lobules the sperm moves out of these tubules and into the Epididymis at first the urethra is surrounded by the prostate gland A thread like tube structure of about 6 m long. It is connected to the ducts within a testis. It stores spermatozoa while they mature and transport them. the sperm enters the Vas Deferens... these two 30 cm long ducts not only connect the left and right epididymis but they then carry the sperm upward to the ejaculatory ducts. after the sperm leaves the Vas deferens through the ejaculatory ducts they pass the opening of the seminal vesicles located near the urinary bladder and base of the ejaculatory ducts, the seminal vesicles secrete a thick yellow substance to nourish the sperm.. this secretion forms 60% of semen's volume sperm containing fluid that is ejaculated at the climax of a male's sexual excitement from here the semen travels into the 8 inch long urethra which transports both urine and semen then it is surrounded and protected by the penis during sexual excitement the penis becomes erect and during the ejaculatory process the prostate glands secrete an alkaline fluid that increases the ability of the sperm to move in the semen the sperm travels up the first canal that connects the cervix to the outside of the body called the vagina this also serves as the birth canal . the sperm continues up and through the cervix... all the way to the fallopian tubes where the egg awaits to be fertilized. . . after a man's sperm has fertilized the egg... the fertilized egg will travel through the fallopian tube and implant in the uterus... CONGRATULATIONS !
you are now considered pregnant ! ...now the uterus becomes the womb the lining of the uterus, ENDOMETRIUM,
provides the nutrients to the embryo during the pregnancy... then the baby grows and grows and grows... VOILA ! you have successfully made a baby !
