Reproductive System-Merari Hernandez Period 5
Reproductive Structures
Female-Uterus, fallopian tubes, labia majora, labia minora,clitoria, ovaries
Male- Primary sex organ is the testes-produces sperm and hormones. Accessory sex glands is internal and external reproductive organs
Major Functions
Only body system a person does not need to survive, develops and maintains organs for production offspring
Female-produce oocytes, houses developing embryo and fetus
Male- produces sperm, hormones. delivers sperm to female
Disorders in System
STI-have similar symptoms such as a fever, sores, blisters or rashes, lower abdominal pain discharge, painful intercourse
AIDS- caused by HIV and can be transmitted by sexual intercourse
Genital Warts-caused by HPV
Chlamydia- caused by chlamydia trachomatis bacteria, symptoms include painful urintation and intercourse mucous discharge from penis or vagina
Genital Herpes- herpes simplex 2 virus, symptoms include genital sores and fever
Gonorrhea
Events of female hormonal cycles
Oogonia give rise to oocytes. Before birth, oogonia multiply by mitosis. During development of the fetus, many oogonia begin meiosis, but stop in prophase I and are now called primary oocytes. They remain in this state until puberty
Before birth the primary oocytes become surronding by a single layer of granculosa cells, creating a primordial follicle, These are present until puberty
After puberty primordial follicles develop into primary follicles when the granulosa cells enlarge and increase in number
Secondary follicles form when the vesicles create a single atrium
Mature follicles for when the vesicles create a single atrium
6.Just before ovulation the primary oocyte completes meosis I creating a second oocyte and a noviable polar body
The secondary oocyte begins meiosis II but stops at metaphose II
During ovulation the secondary is released from the ovary
9.The secondary oocyte completes meiosis II only if it is fertilized by a sperm cell. The completion of meiosis II forms of an oocyte nucleus and the sperm cells nucleus unite creating a zygo
Following ovulation the granulosa cells divide rapidly and enlarge to form the corpus letuem
The corpus leteum degenerates to form a scar or corpus albicans
