Ovary

produces hormones and eggs

Follicle

cluster of cells that surround, protect, and nourish a developing egg cell in an ovary

Oviduct

tube that conveys egg cells away from the ovary toward the uterus; the usual site of fertilization

Uterus

in female mammals, the organ where the young develop before birth

Cervix

neck of the uterus, opening into the vagina

Vagina

part of the female reproductive system that leads from the uterus to the outside of the body; functions as the birth canal and the passageway for menstrual flow

Testis

male reproductive organ that produces sperm and hormones

Scrotum

sac that houses the testes outside the abdomen

Epididymis

long, thin-coiled tube where sperm mature and are stored

Semen

sperm-containing fluid that is released from the penis during ejaculation

Vas deferens

tube that conveys sperm between the epididymis and the urethra

Penis

male reproductive organ; also contains the urethra and functions in eliminating urine from the body

Ovulation

release of a secondary oocyte from an ovarian follicle

Ovum

mature egg cell with a haploid nucleus

Ovarian cycle

cyclic changes that occur in the ovaries

Endometrium

inner lining of the uterus; site of implantation of the embryo

Menstrual cycle

cyclic changes that occur in the uterus

Menstruation

discharge resulting from shedding of the endometrium during the menstrual cycle

Corpus luteum

ovarian structure that forms from a follicle after ovulation; secretes progesterone and estrogen

Fertilization

the fusion of the nucleus of a haploid sperm cell and the nucleus of a haploid egg cell, forming a diploid zygote

Zygote

diploid cell formed when the nucleus of a haploid sperm cell fuses with the nucleus of a haploid egg cell

Blastocyst

stage in human embryonic development; fluid-filled ball of cells that implants in the endometriu

Cleavage

series of rapid mitotic divisions of a zygote

Trophoblast

outer cells of the blastocyst that secrete enzymes that allow implantation

Embryo

stage in human development from the first division of the zygote until about nine weeks after fertilization

Gastrulation

developmental process in which three distinct cell layers form in an embryo: the endoderm, mesoderm, and ectoderm

Implantation

imbedding of a blastocyst into the endometrium

Placenta

organ that develops inside the uterus and enables the transfer of nutrients, gases, and waste products between the mother and developing baby

Fetus

stage of human development from nine weeks after fertilization until birth

Labor

series of rhythmic contractions of the uterus that expel the baby from the uterus, resulting in birth

Oxytocin

hormone secreted by pituitary gland that stimulates contractions of the uterus

Puberty

stage of human development when reproductive organs become functional and secondary sex characteristics develop

Menopause

point in life when a woman stops ovulating, usually in her 50s

Gynecology

medical specialty that focuses on wellness of the female reproductive system

Urology

medical specialty that focuses on the wellness of the urinary tract in males and females, and also the male reproductive system
