| parotid gland | Either of a pair of large serous salivary glands situated below and in front of the ear [Brenda]. | — |
| submandibular gland | One of the three chief, paired salivary glands, predominantly serous, lying partly above and partly below the posterior half of the base of the mandible [Brenda]. | — |
| sublingual gland | Gland situated or administered under the tongue; the smallest of the three salivary glands, occurring in pairs, predominantly mucous in type, and draining into the oral cavity through 10 to 30 sublingual ducts [Brenda]. | — |
| duodenum | The first part of the small intestine extending from the pylorus to the jejunum [Brenda]. | — |
| jejunum | The section of the small intestine that comprises the first two fifths beyond the duodenum and that is larger, thicker-walled, and more vascular and has more circular folds than the ileum [Brenda]. | — |
| ileum | The last division of the small intestine extending between the jejunum and large intestine [Brenda]. | — |
| colorectal | Colorectal includes the colon and the rectum [MedTerms: http://www.medterms.com/script/main/art.asp?articlekey=2794]. | — |
| anus | The posterior opening of the alimentary canal [Brenda]. | — |
| testis | A typically paired male reproductive gland that produces sperm and that in most mammals is contained within the scrotum at sexual maturity [Brenda]. | — |
| epididymis | A 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 [Brenda]. | — |
| prostate | The prostate (from Greek ÏÏοÏÏάÏÎ·Ï - prostates, literally "one who stands before", "protector", "guardian") is a compound tubuloalveolar exocrine gland of the male reproductive system in most mammals [Wikipedia: http://en.wikipedia.org/wiki/Prostate]. | — |
| vas deferens | A spermatic duct especially of a higher vertebrate that in the human male is a thick-walled tube about two feet (0.61 meters) long that begins at and is continuous with the tail of the epididymis and eventually joins the duct of the seminal vesicle to form the ejaculatory duct [Brenda]. | — |
| penis | A male organ of copulation that in male mammals including humans usually functions as the channel by which urine leaves the body [Brenda]. | — |
| ovary | One of the typically paired essential female reproductive organs that produce eggs and in vertebrates female sex hormones [Brenda]. | — |
| uterine tube | The Fallopian tubes, also known as oviducts, uterine tubes, and salpinges (singular salpinx) are two very fine tubes lined with ciliated epithelia, leading from the ovaries of female mammals into the uterus, via the utero-tubal junction. In non-mammalian vertebrates, the equivalent structures are the oviducts [Wikipedia: http://en.wikipedia.org/wiki/Fallopian_tube]. | — |
| uterus | An organ of the female mammal for containing and usually for nourishing the young during development previous to birth [Brenda]. | — |
| vagina | A canal in a female mammal that leads from the uterus to the external orifice of the genital canal [Brenda]. | — |
| vulva | The vulva (from the Latin vulva, plural vulvae, see etymology) consists of the external genital organs of the female mammal. This article deals with the vulva of the human being, although the structures are similar for other mammals [Wikipedia: http://en.wikipedia.org/wiki/Vulva]. | — |
| 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; also: an analogous organ in another animal [Brenda]. | — |
| chorion | The outer membrane of the two membranes enclosing the embryo in reptiles, birds, and mammals. In placental mammals it contributes to the development of the placenta [Brenda]. | — |
| amnion | A thin, tough, membranous sac that encloses the embryo or fetus of a mammal, bird, or reptile. It is filled with a serous fluid in which the embryo is suspended [Brenda]. | — |
| amniotic fluid | Fluid within the amniotic cavity produced by the amnion during the early embryonic period, and later by the lungs and kidneys; at first crystal clear, it later becomes cloudy. It protects the embryo and fetus from injury. The amount at term normally varies from 500 to 1500 mL [Brenda]. | — |
| breast | The fore or ventral part of the body between the neck and the abdomen [Brenda]. | — |
| milk | A fluid secreted by the mammary glands of females for the nourishment of their young; especially: cow's milk used as a food by humans [Brenda]. | — |
| umbilical cord | A cord arising from the navel that connects the fetus with the placenta [Brenda]. | — |
