To produce male gametes called sperm and reliever them to the woman's reproductive tract. The also produce testosterone.
The primary sex organs such as the testes in men and the ovaries in women
An organism in its early stages of development; in humans, first two months after conception
The fertilized ovum; produced by Union of two gametes
The female sex organ in which eggs are produced
The sperm-contains fluid that is propelled out of the male's reproductive tract during ejaculation. It is a milky white, somewhat sticky mixture of sperm and accessory gland secretions
Where is semen formed?
In the paired seminal vesicles, the single prostate, and the bulbourethral glands.
Where is semen stored?
The process of sperm production in the male; involves meiosis
The process of formation of the ova
What are the male secondary sex characteristics?
Deepening of voice, increased hair growth, enlargement of skeletal muscles to help produce the heavier muscle mass typical of the male physique, increased heaviness of the skeleton due to bone growth and increase in density
What are the female secondary sex characteristics?
Enlargement do uterine tubes, uterus, vagina, external genitals; development of breasts; appearance of axillary and public hair; increased deposits of fat beneath the skin in general, and particularly in the hips and breasts; widening and lightening of the pelvis; the menstrual cycle
Inner layer or mucosa of the uterus
Layer of the uterus that is composed of interlacing bundles of smooth muscle, it is also the middle layer
The outermost serous layer of the uterus
Hormones that stimulate female secondary sex characteristics; female sex hormones
Helps maintain the pregnancy by inhibiting contraction of the Myometrium of the uterus, and prepare the breasts for milk production; it is produced by the glandular corpus luteum
During puberty, as the seminiferous tubules are being prodded to produce sperm by...
Activates the interstitial cells; it is also released by the anterior pituitary gland
Male sex hormone produced by the testes; during puberty promotes virilization and is necessary for normal sperm production
Regulates the endocrine activity of the cortex portion of the adrenal galnd
The superficial functional layer of the thick endometrial lining of the uterus is sloughing off from the uterine wall. 3-5 days of bleeding
Days 1-5: Menstrual phase
Stimulated by rising estrogen levels produced by the growing follicles of the ovaries, the basal layer of the endometrium regenerates the functional layer, glands form in it, and the endometrial blood supply increases
Days 6-14: proliferation phase
Rising levels of progesterone production by the corpus luteum of the ovary act on the estrogen behind endometrium and increase its blood supply even more.
Days 15-28: secretory phase
Are present in both sexes but they normally function only in women
A pigmented area that is slightly below the center of each breast
The Areola surrounds a central protruding what?

The time from the appearance of true contractions until the cervix is fully dilated by the babies head. As labor starts regular week uterine contractions began in the upper part of the uterus and move downward toward the vagina. Gradually the contractions become more rapid and as the infants head is forced against the cervix with each contraction the cervix begins to soften becomes thinner and dilates.
Stage 1: dilation stage
The period from full dilation to delivery of the infant. In this stage, The infant passes through the cervix and vagina to the outside of the body. During this stage a mother experiencing natural childbirth has an increasing urge to push for bear down with the abdominal muscles.
Stage 2: expulsion stage
The delivery of the placenta is usually accomplished within 15 minutes after birth of the infant. The strong uterine contractions they continue after birth compress uterine blood vessels, limit bleeding, and cause the placenta to detach from the uterine wall. The placenta and it's attached fetal membranes, collectively called the afterbirth, then easily removed by a slight tug on the umbilical cord.
Stage 3: placental stage
At puberty, perhaps 250,000 oocytes remain; and, beginning at this time, a small number of oocytes are activated each month. There's typically one ovulation each month.
