HUMAN REPRODUCTION Flashcards
Male gonad that produces and nourishes sperm cells
Testes
External sac that regulates temperature for testis
Scrotum
Stores sperm cells produced and transports them to vas deferens
Epididymis
Common exit duct for both the urine and semen
Urethra
Pathway of sperms from testis to the urethra
Vas Deferens
Contributes alkaline fluid that nourishes and protects sperm cells
Seminal Vesicle
Contributes a fluid that neutralizes semen and vaginal fluid
Prostate Gland
Contributes a fluid that functions for lubrication
Bulbourethral Gland
Copulatory organ that conveys sperm to female reproductive tract
Penis
Female gonad that produces and nourishes egg cells
Ovary
Ducts that serve as fertilization site and leads to the uterus
Fallopian Tubes
Appendages of the fallopian tubes that catch eggs during ovulation
Fimbriae
Highly vascularized sac that nourishes the developing embryo
Uterus
Narrow channel that prevents further entry of foreign materials
Cervix
Receives the sperm cells and serves as the birth canal
Vagina
Accessory structures of the female reproductive system
External Genetalia
Produces fluid that serves as lubrication during intercourse
Bartholin’s Gland
● Reduction of the chromosome number
● Spermatogenesis or oogenesis
● Makes sperm cells sufficiently motile
● Produces egg cells with enough nutrients
Gametogenesis
● Occurs in the seminiferous tubules of male testis
● Nourishing cells include the Sertoli cells
● Starts during puberty and continuous throughout life
Spermatogenesis
● It occurs in the ovaries and fallopian tubes.
● The follicles of the ovary exert hormonal influence.
● It starts during the pregnancy of the mother.
Oogenesis
the resulting zygote from fertilization undergoes repeated cell divisions and reorganization.
Pre-Implantation Phase
contains the fluid that surrounds the developing embryo.
amnion
serves as the initial nourishment source of the embryo.
Yolk Sac
initially collects liquid wastes and facilitates gas exchange.
allantois
