Marvelyn Breceda 6th period, Reproductive system
Anatomy of female reproductive structures :check:
deliver, feed, and nurture off spring
medulla
made up of connective tissue, blood vessels, lymphatic vessels,and nerves
primary sex organs(gonads) are ovaries
uterine tubes (oviduct or Fallopian tubes)
produce and maintain sex cells ( egg cells,oocytes)
uterus
hallow, muscular organ
vagina
fibromucular tube extends from the uterus to outside
Major functions of the Reproductive system (male and female) :check:
gonads testes and ovaries
male sex cells- sperm
develops and maintains organs for production off spring
female sex cells- oocytes
Only body system a person does not need to survive
Hormones of the reproductive system (male and female) :check:
andogens
low androgen
concentration allows the broadening of the hips
pubic and axillary hair
hypothalamus begins to secrete
more GnRH, which in turn stimulates the anterior pituitary
to produce LH and FSH
progesterone
main source are the ovaries
triggers uterine changes during menstrual cycle
estrogen
sex organ enlargement
increased adipose tissue deposition
breast development
Anatomy of male reproductive structures :check:
channels leading from seminiferous tubules our carry sperm to epididmis
interstitial cells lie between seminiferous tubules and produce male sex hormones
seminiferous tubules
lined with stratified epithelium that contains spermatogenic cells give rise to sperm cells
epididymis
seminal vesicle
prostate gland
ductus defermens
bulbourthral gland
testes
each testis consists of 250 lobules separated by connective tissue septa
Events of the female hormonal cycles :check:
Menarche
first female reproductive cycle
FSH stimulates the maturation of a follicle in the ovary
ovulation
process of releasing the secondary oocyte and polar body from mature antral folloicle and the surface of the ovary
Follicular cells produce and secrete estrogens.
anterior pituitary releases a surge of LH, which leads to ovulation.
Follicular cells become corpus luteum cells, which secrete estrogens and
progesterone.
Disorders associated with the reproductive system :check: :
Genital warts
Human papilloma virus
(HPV)
Genital herpes
Herpes simplex 2 virus
(HSV2)
Chlamydia infection
Chlamydia trachomatis
bacteria
Gonorrhea
Neisseria gonorrhoeae
bacteria
acquried immune deficiency syndrome
human immunodeficieny
Syphilis
Treponema pallidum
bacteria
Methods and Classification of contraceptives :check:
Mechanical Barriers
prevent sperm from entering vagina
Chemical Barriers
contain spermicides are more effective
when used with a condom
birth control
avoid fertilization
prevent implantation
Combined Hormone Contraceptives
contain estrogen and
progestins to prevent pregnancy
Contraceptive Implants
prevent follicle
maturation and ovulation for 3 years
