3167089051	corpus luteum	A yellow glandular mass in the ovary formed by an ovarian follicle that has matured and discharged its ovum.	0
3167089052	Male organs	Testes: the sperm-producing organs (testosterone is the hormone). Sperm: male gamete and is highly specialized for its role as a carrier of genetic information. Semen:The fluid released at orgasm which contains sperm and secretions from the prostate gland.	1
3167091842	prostate gland	A gland in the male that surrounds the neck of the bladder and urethra. The prostate contributes to the seminal fluid.	2
3167094871	uterus	The hollow muscular organ in female mammals in which the fertilized ovum normally becomes embedded and in which the developing embryo and fetus is nourished. Uterine cycle: Cyclic operation of the uterus whose function is to prepare the lining of the uterus, called the endometrium, to receive a possible embryo in case of fertilization.	3
3167096514	penis vs vagina	Penis: external tube containing two long cylinders of spongy tissue. designed to inflate. Vagina: The female organ of sexual intercourse, the birth canal.	4
3167098211	ovary	Ovary: these are located in the outer layer of compact masses of cells. Ovarian cycle: The normal sex cycle that includes development of an ovarian follicle, rupture of the follicle, discharge of the ovum, and formation and regression of a corpus luteum. Ovulation: during each reproductive cycle, one or a few of these oocytes are initiated to continue their development	5
3167100558	seminal vesicles vs seminiferous tubules	Seminal vesicles: Each of a pair of glands that open into the vas deferens near its junction with the urethra and secrete many of the components of semen. Seminiferous tubules: each compartment is packed with large numbers of tightly coiled tubes (site of spermatogenesis).	6
3167104173	HIV vs AIDS	Human Immunodeficiency Virus: Type 1: the retrovirus recognised as the agent that induces aids. Type 2: a virus closely related to hiv-1 that also leads to immune suppression. Acquired Immunodeficiency Syndrome:An epidemic disease caused by an infection by HIV a retrovirus that causes immune system failure and debilitation and is often accompanied by infections such as tuberculosis (spread through bodily fluids)	7
3167112305	follicle	An ovarian follicle, an oocyte surrounded by one or more layers of granulosa cells. Follicular Phase: phase of the estrous cycle during which follicles in the ovary mature, ends at ovulation.	8
3167113542	estrogen	A general term for female steroid sex Hormones that are secreted by the ovary and responsible for typical female sexual characteristics.	9
3167115996	gonad	sex organs (testes for males and ovaries for females).	10
3167117837	menopause vs menstruation	Menopause: Cessation of menstruation in the human female, occurring usually around the age of 50. Menstruation: female reproductive cycle, follicular phase in which an egg reaches maturation and is ovulated the luteal phase where the body prepares for pregnancy.	11
3167120956	reproductive system for women	Egg: An organic vessel where an embryo develops, and one in which the female of an animal species lay as a means of reproduction (Ovum). Fallopian tubes: The fallopian tubes (also known as uterine tubes, or oviducts) transport eggs from the ovaries to the uterus cervix: uterus narrows to a muscular ring. Placenta: An organ characteristic of true mammals during pregnancy, joining mother and offspring, providing endocrine secretion and selective exchange of nutrients.	12
3167128864	lactation	The period of the secretion of milk. Luteal Phase: The post-ovulatory phase of a woman's cycle, which in turn causes the uterine lining to secrete substances to support the implantation and growth of the early embryo.	13
3167131740	yolk	Nutritive material of an ovum stored for the nutrition of an embryo.	14
3167131741	gamete	By the union of two cells, which are formed by meiosis in the sex organs	15
3167133213	germ line	The reproductive cells in multicellular organisms.	16
3167138699	endometrium	The tissue lining the uterus, it is sloughed off during the woman's menstrual period, and afterward grows back and slowly gets thicker and thicker until the next period.	17
3167140759	vas deferens	from the epididymis, the sperm is delivered to another long tube then it travels to the urethra to be released.	18
3167140760	oocyte	eggs develop from cells. primary oocyte waits to receive the proper developmental signal to continue on with meiosis	19
3167140761	extraembryonic membrane	a structure or tissue that develops from the fertilised ovum but does not form part of the embryo proper.	20
