reproductive voc

1. corpus luteum: a yellowish mass of progesterone-secreting endocrine tissue that forms immediately after ovulation from the ruptured graafian follicle in the mammalian ovary
2. epididymisa system of ductules emerging posteriorly from the testis that holds sperm during maturation and that forms a tangled mass before uniting into a single coiled duct which is continuous with the vas deferens
3. gonad: a reproductive gland (as an ovary or testis) that produces gametes
4. meiosis: the presentation of a thing with underemphasis especially in order to achieve a greater effect
5. oocyte: an egg before maturation
6. ovary: one of the typically paired essential female reproductive organs that produce eggs and in vertebrates female sex hormones
7. placenta: the vascular organ in mammals except monotremes and marsupials that unites the fetus to the maternal uterus and mediates its metabolic exchanges through a more or less intimate association of uterine mucosal with chorionic and usually allantoic tissues
8. scrotum: the external pouch that in most mammals contains the testes
9. seminiferous tubule: any of the coiled threadlike tubules that make up the bulk of the testis and are lined with a layer of epithelial cells from which the spermatozoa are produced
10. testis: a typically paired male reproductive gland that produces sperm and secretes testosterone and that in most mammals is contained within the scrotum at sexual maturity
11. vulva: the external parts of the female genital organs
12. blastocyst: the modified blastula of a placental mammal having an outer layer composed of the trophoblast
13. embryo:a vertebrate at any stage of development prior to birth or hatching
14. fetus: an unborn or unhatched vertebrate especially after attaining the basic structural plan of its kind
15. implantation: the process of attachment of the early embryo to the maternal uterine wall
16. lactation: to secrete milk
17. umbilical cord: a cord arising from the navel that connects the fetus with the placenta and through which respiratory gases, nutrients, and wastes pass
18. yolk sac: a membranous sac of most vertebrates that encloses the yolk, is attached in most forms (as in humans) through the yolk stalk with the intestinal cavity of the embryo,
19. zygote: a cell formed by the union of two gametes; broadly : the developing individual produced from such a cell
20. ultrasound: vibrations of the same physical nature as sound but with frequencies above the range of human hearing
