Slide 1-

The Human Body: The Reproductive System
Slide 2-

Review Mitosis is the type of cell division that occurs in non-reproductive cells. Produces exact copies of the parent cell Meiosis is cell division that occurs in reproductive cells; gametes. Produces egg and sperm cells with half the genetic material of the parent cells. 23 chromosomes are contained in gametes; this is so that when egg and sperm meet, they produce offspring with 46 chromosomes.

Organs of the Male Reproductive System Penis Urethra Vas Deferens Scrotum Testes Bladder* *Not a part of the reproductive system
Slide 4-

External Organs of the Male Reproductive System Penis: the external reproductive organ, urethra passes through the penis and allows urine and semen to exit the body. Scrotum: a sac or pouch which holds the testes. The function of the scrotum is to maintain the proper temperature of the testes. (slightly cooler than body temperature) Sperm is destroyed unless a temperature of 97o is maintained.
Slide 5-

Internal Organs of the Male Reproductive System Bladder*: holds urine prior to urination. Urine leaves the bladder via the urethra. (Not part of reproductive system) Urethra: a tube which allows urine and semen to exit the body. Connects to the bladder
Slide 6-

Internal Organs of the Male Reproductive System Prostate: gland that secretes fluid which is a component of semen. Vas deferens: a tube which connects the testes to the urethra and allows semen to exit the body. Testes: two glands which produce sperm and hormones (testosterone)

Organs of the Female Reproductive System Vagina Cervix Uterus Fallopian Tubes Ovary
Slide 8-

Organs of the Female Reproductive System Vagina: also called the birth canal, a tube leading from the uterus to the outside of the body. (Where sperm enters. It is acidic.) Cervix: the lower portion of the uterus; where the vagina and uterus meet. (Dilates for the delivery of baby.)
Slide 9-

Organs of the Female Reproductive System Uterus: a hollow, fist-sized organ located between the bladder and rectum. (Where the zygote implants and the embryo develops) Fallopian Tubes: also called oviducts; are two tubes connecting the uterus with the ovaries. (site of fertilization)
Slide 10-

Organs of the Female Reproductive System Ovaries: small organs on the ends of the Fallopian tubes responsible for the production and release of eggs (ova-pl). Females are born with all of the eggs they will ever produce. Ovaries alternate the release of eggs each month. Like testes, the ovaries produce hormones-estrogen. This release of the ova is called ovulation.
Slide 11-

The Menstrual Cycle The menstrual cycle typically lasts 28 days; approximately 1 month. One cycle is the amount of time from the beginning of one period to the beginning of the next period. The beginning of a period is marked by the release of the blood and lining from the inside of the uterus. This flow of blood typically lasts 3-7 days and is called menstruation.
Slide 12-

The Menstrual Cycle After menstruation, the ovaries release hormones that tell the uterus to grow a new lining and prepare to receive a new egg. As the uterus prepares a new lining, one of the ovaries releases an egg. This is called ovulation. Ovulation occurs about halfway through a woman’s cycle. The egg travels through the Fallopian tube. If it is not fertilized it breaks down and is released with the lining and blood of the uterus.

The Menstrual Cycle and Fertilization If the egg is fertilized by a sperm cell, the egg will implant in the lining of the uterus and begin to develop. Zygote: The first cells of a new organism; the time from fertilization to implantation. Embryo: The zygote is called an embryo from implantation to 8 weeks. Fetus: After 8 weeks of development, the embryo is known as a fetus. *To get from zygote to fetus, mitosis and differentiation occurs
