Human Reproductive System
Male reproductive system
Reproductive organs
Vasa Deferentia
Rapid transport of sperm
Ejaculatory Ducts
Conduct sperm to penis
Epididymides
Site of sperm maturation and subsequent storage
Penis
Organ of Sexual Intercourse
Testes
Sperm
Sex hormone production
Accesory glands
Prostate Gland
Secretes some fluid in semen
Bulbourethral Glands
Secrete Lubricating mucus
Seminal Vesicles
Secrete Most Fluid in Semen
Female Reproductive Organs
Uterus
Chamber where new individual develops
Cervix
Secretes mucus that enhances sperm movement into uterus and (after fertilization) reduces the embryo's risk of bacterial infection
Oviducts
Conduct oocytes from ovary to uterus
Vagina
Organ of sexual intercourse; birth canal
Ovaries
Produce oocytes and sex hormones
Hormones control sperm formation
Leydig cells
In tissue between the seminiferous tubules
Produce testosterone
Governs growth, form, and functions of the male reproductive tract
Promotes
secondary sexual traits
: facial hair and deepening of the voice
Stimulates sexual behavior
Sperm form inseminiferous tubules
Sperm
(spermatozoa)
Mature sperm: 9-10 week of processing
Tail
(flagellum)
Midpiece
; contains mitochondria
Nourished with secretions from
sertoli cells
Head
Nucleus with DNA organized into chromosomes
Acrosome
: cap with enzymes to penetrate egg
Ovaries are a female's primary reproductive organs
Ovaries
Release sex hormones
Secondary sexual traits: fat deposits in breasts, hips and buttocks
Produce eggs during reproductive years
Oocytes
(immature eggs)
Release into
oviducts
(site of fertilization)
Travel to
uterus
Vagina
Leads from the cervix to the outside
Uterus
Myometrium
(thick layer of smooth muscle) and
endometrium
(lining)
Cervix:
lower portion of the uterus
Organ where baby grows and develops
Menstrual phase
The menstrual phase is the
first stage
of the menstrual cycle. It's also when you get your
period
.
This phase starts when an egg from the previous cycle isn't fertilized. Because pregnancy hasn't taken place,
levels of the hormones estrogen and progesterone drop
.
The
thickened lining of your uterus
, which would support a pregnancy, is no longer needed, so it
sheds
through your vagina. During your period, you release a combination of blood, mucus, and tissue from your uterus.
On
average
, women are in the menstrual phase of their cycle for 3 to 7 days.
Some women have longer periods than others.
Period symptoms

Headaches
Mood swings
Tiredness
Bloating
Low back pain
Cramps
