4.6 Homeostasis and Reproduction System Flashcards
What is the function of the teste?
Produce sperm and testosterone
What is function of seminiferous tubules?
Produce immature sperm cells
What is the function of Epididymis?
stores and matures sperm cells in coiled tubules
What is the function of vas deferens?
Carries sperm from epididymus to urethra
What is the function of seminal vesicle?
Secrete fructose into semen which provides energy for sperm
What is the function of the prostate gland?
Secrete base buffer into semen to protect sperm from acidic vagina
What is the function of cowpers gland?
Secrete mucous rich cells into semen to protect from acidic vagina
What is the job of the urethra in the male body? (2)
Tube to carry semen out of the body during ejaculation
Tube to carry urine out the body from the bladder
What is the job of the penis?
Deposit sperm into the vagina
What are the outer characters of male secondary sexual characteristics? (8)
development of facial hair, body hair, growth of the larynx, lower voice, stronger muscles, secreting more body oils (responsible for acne and odour) Maturation of testes, maturation of penis
What produces testosterone in the body?
Interstitial cells of the testes (cells in the teste)
What does testosterone influence? (3)
Influences development of secondary male characteristics
influences sex drive
Influences spermatogenesis
What produces gonadotropic hormones?
The pituitary gland
What is the job of gonadotropic hormones in males?
Regulate the function of the testes
Where is the male follicle stimulating hormone produced and stored?
In the pituitary
What is the job of the male follicle stimulating hormone in males?
Stimulate production of sperm cells in seminiferous tubules
Where is the male lutenizing hormone produced and stored?
The pituitary
What is the job of the male luteniizng hormone?
Promote production of testosterone by interstitial cells in the teste
Which gland secretes the gonadotropin releasing hormone?
Hypothalamus
When is gonadotropic releasing hormone secreted? What is its job?
Secreted at puberty
Activate pituitary to secrete follicle stimulating hormone and lutenizing hormone
What type of cell do ovaries contain
Follicle
What are the two distinct types of follicle cells? How many follicles remind after menopause?
Primary procure and granulosa cells
Few new follicles remind after menopause
What is the job of primary oocyte?
46 chromosomes
Undergo meiosis to turn into a mature oocyte or ovum
What is the job of granulosa cells?
Provide nutrients to the oocyte cells
Around what age do female overuse undergo continual decline
12-50
In a female life about how many eggs will mature
400
What is the function of the ovaries?
Site of egg cell development and ovulation
Produce estrogen and progesterone
What is the job of the fallopian tube?
Site of fertilization
Carry ovum from ovary to uterus
What is the oviduct?
the tube through which an ovum or egg passes from an ovary.
What is the job of fimbria?
Sweep ovum into oviduct during ovulation
What is the appearance of the uterus?
Pear shaped organ
What is uterus used for?
Embryo and fetus development
What is the appearance of the cervix?
pathway separating vagina and uterus
What is the function of the cervix? (2)
Hold fetus in place during pregnancy
Dilates during birth to allow fetus to exit
What is the appearance of the vagina?
region starting from cervix to the outside
What is the job of the vagina? (3)
Provide passage for sperm
passage for menstrual flow
Functions as the birth canal
What are female secondary sex characteristics? (6)
thicker hair on the head in some cases, breast, ability to nurse children, rounded hips, decrease ability to generate muscle mass at a fast rate, increased body fat composition, relative lack of body hair
Where is estrogen secreted from? what’s is it regulated by?
Ovaries
Regulated by the pituitary
What is the function of estrogen?
Helps with the maturating and release of an ovum in every menstrual cycle
What produces progesterone?
The corpus luteum in the ovary
What is the function of progesterone?
Prepare the inner lining of the uterus (endometrium) for shedding
Suppress production of estrogen after ovulation has occurred
