Reproductive System Delia Ocampo P.2 - Coggle Diagram
Reproductive System Delia Ocampo P.2
Major Functions(Male and Female)
Male:
-Develops and maintains organs for production of offspring
-Delivers sperm to female
Female:
-Produces and maintains sex cells(egg cells and oocytes)
-Transports the cells to the site of fertilization
-Provides environment for a developing fetus
-Delivers,feeds,and nurtures offspring
-Produces female sex hormones
Female Reproductive Structures
Ovary:produces oocytes and female sex hormones
Uterine tube: conveys secondary oocyte toward uterus also the site of fertilization
Uterus: protects and sustains embryo during pregnancy
Vagina: conveys uterine secretions to outside of the body and provides a passageway for offspring during birth process
Labia majora: encloses and protects other external reproductive organs
Labia minora: protects openings of vagina and urethra
Clitoris:produces feelings of pleasure during sexual stimulation
Vestibule: space between labia minora that has vaginal and urethral openings
Vestibular glands: secreted fluids that moistens and lubricates vestibule
Male Reproductive Structures
Ductus Deferens: muscular tube leading from epidymis into body cavity
Seminal Vesicles: saclike structure attached to the vas defferens near the base of the urinary bladder
Bulbourethral Glands: small glands located inferior to prostate gland
Prostate gland: chestnut-shaped structure surrounding the urethra at the base of the urinary bladder
Scrotum: a pouch of skin and subcutaneous tissue that houses the testes
Penis: cylindrical organ that conveys both urine and semen to the outside
Male and Female Hormones
MaleHormones:
-Gonadotropin releasing hormone(GnRH): secreted by the hypothalamus and triggers the production of gonadotropins from the anterior pituitary gland
-Luteinizing hormone(LH): promotes the development of interstitial cells of the testes which then secretes male hormones
-Follicle stimulating hormone(FSH): stimulates sertoli cells of seminiferous tubules to respond to testosterone
Female Hormones:
-Progesterone:prevents the wall of the uterus from breaking down
-Estrogen:initiates secondary female characteristics and causes thickening of the endometrium
-FSH: stimulates the development of the follicle cells in the ovary
LH: stimulates ovulation and the formation and maintenance of the corpus luteum
Disorders/STI'S
-Syphilis:a sexually transmitted infection that can cause serious health problems if not treated and you can get it by direct contact with a person who has it and can be treated with antibiotics
-Gonorrhea: a sexually transmitted disease that can infect both men and women and it can be transmitted by having sex with someone who has it you can experience symptoms that can be treated with medication
-HPV:the most common sexually transmitted infection which can be transmitted by having sex with someone who has the virus sometimes no symptoms can be expirenced but you can get vaccinated for it
IUD:one time procedure
Pill:it is a pill that you can take by mouth everyday at the same time
Internal and external condoms:provides protection against some STD's
Withdrawal :pull penis out of vagina before ejaculation
Female hormonal cycle
-Menstruation:the elimination of the thickened lining of the uterus from the body through the vagina
-Follicular phase: starts on the first day of menstruation and ends with ovulation
-Ovulation: the release of a mature egg from the surface of the ovary and usually occurs mid cycle
-Luteal phase:during ovulation the egg bursts from its follicle but the ruptured follicle stays on the surface of the ovary
Methods and Classification of contraceptives
Coitus Interruptus:withdrawal of penis from vagina before ejaculation
Rhythm Method:abstinence from sexual intercourse around time of ovulation
Mechanical Barriers:prevents sperm from entering vagina during sexual intercourse
Chemical Barriers:contains spermicides
Combined hormone contraceptives:contains estrogen and progestins to prevent pregnancy
