male and female reproductive system Flashcards
Components of the male reproductive system
el pp, vas deferens, urethra, prostate, seminal vesicles, testis, and scrotum.
scrotum
a sac that houses the testes away from the body to lower their temperature during sperm production.
Sperm does not mature properly at normal body temperature and higher
testis
primary reproductive organs; contain seminiferous tubules where sperm is produced.
sperm produced by testosterone and FSH
prostate and seminal vesicles
produce the fluids necessary for lubricating and nourishing the sperm
components of the female reproductive system
ovaries, fallopian tubes, uterus, cervix, vagina, labia minora, labia majora, and the clitoris.
labia minora and majora
open into the vagina
vagina
birth canal that connects to the uterus through the cervix
fallopian tubes
connect the ovaries to the uterus
ovaries
changing hormone levels cause a follicle in the ovary to mature and release an egg that travels down the tubes to the uterus.
the primary roles of the female reproductive system
generating female gametes (ova, or eggs), fertilization (conception), implantation (start of pregnancy), gestation (pregnancy), and parturition (birth).
zygote
fertilized egg with full set of genetic material resulting from merging of egg and sperm nuclei
several divisions make it turn into a blastocyst
puberty
changes in hormone levels cause a general “growth spurt” and development of secondary sex characteristics.
how puberty is initiated
initiated by the production of gonadotropin-releasing hormone from the hypothalamus which triggers the release of follicle-stimulating hormone (FSH) and luteinizing hormone (LH) from the anterior pituitary gland.
follicle stimulating hormone (FSH)
secreted by the pituitary gland that stimulates the development of eggs and sperm.
luteinizing hormone
secreted by the anterior pituitary gland that is responsible for triggering ovulation and the production of testosterone.
