4. Continued Male Repro. System
Prostate Gland- produces fluid that aids in sperm longevity.
Urethra- tube that runs through the penis and releases sperm and urine from the penis.
Seminal Vesicles- small glands at the end of the vas deferens which secrete a fluid that is a source of energy for sperm.

Cervix- the lowest part of the uterus.
Fallopian Tube (oviduct)- tube that extends from near the ovaries to the uterus. Fimbria- the ends of the oviduct.
Endometrium (uterine lining)- the inner lining of the uterus. Thickens to prepare for pregnancy.
Estrogen- female sex hormone produced in ovaries.

10. Menstrual Cycle
Menstruation (menstrual period)- the monthly breakdown and shedding of the endometrium. This cycle lasts about 28 days.
Ovulation- when the ovaries release a mature egg/ova from the ovaries.
Fertilization- the joining of the male sperm and the female egg. This takes place in the fallopian tube/oviduct.
