The Reproductive System

Hannah Cantrell
Across
A tissue in the body that becomes stiff when filled with blood
A donut-shaped gland which secretes fluid into the semen. This gland lies just below the bladder
A pair of muscular tubes that extend from the uterus to their corresponding ovary. The ducts consists of an interstitium, isthmus, ampulla, infundibulum, and fimbriae. These ducts transport eggs from the ovaries to the uterus. The duct's wall is composited of three layers: the mucosa, muscularis, and serosa
A hollow, pear-shaped organ in which a fertilized egg develops into a fetus. It is located in the lower abdomen (behind the bladder and in front of the rectum)
An elastic band of tissue under the glans penis that connects the foreskin (prepuce) to the vernal mucosa, and helps contract the foreskin over the glans
The broader upper part of the uterus which is made up of three layers of tissue: endometrium, myometrium, and perimetrium
The rounded part forming the end of the penis or clitoris
The mucous membrane lining the uterus, which thickens during the menstrual cycle in preparation for the possible implantation of an embryo
_ deferens is a long, muscular tube that travels from the epididymis into the pelvic cavity, to just behind the bladder. This tube transports mature sperm to the urethra in preparation for ejaculation
_ pubis is the area in front of the pelvis where the pubic bones meet
Female sex cells (eggs) (each ovum contains twenty-three chromosomes)
The uniting of the sperm and ovum into one cell
The external male sex organ for urination and reproduction. This organ is an elongated, cylindrical structure made of connective and erectile tissue that extends outside the body from the base of the pelvis. The penis itself is made up of three tissue sections. The first two form the corpus cavernosa, and the third is the corpus spongiosum
A female steroid hormone released by the corpus luteum that stimulates the uterus to prepare for pregnancy
The release of a mature ovum (egg) through a fallopian tube, which is then made available to be fertilized
Male sex cells (each cell contains twenty-three chromosomes)
Glands that are made up of glandular tissue and fat and which secrete milk after childbirth. They are located on the outside of the female chest
Two pea sized glands which are located on either side of the vaginal opening. These glands secrete a thick mucus to help lubricate and moisten the vagina
A small mass of erectile tissue and nerves in the female that is situated at the anterior apex of the vulva, near the meeting of the labia major. This organ becomes hard and pleasurable when sexually stimulated
The retractable roll of skin covering the end of the penis
The narrow lower portion of the uterus (the neck) which connects to the vagina
A thin membrane that partially or completely covers the opening of the vagina
A muscular canal extending from the cervix to the outside of the body. It provides access to the uterus for insertion of semen and from the uterus for the birth of a baby
Down
Two peas-sized glands under the prostate. They produce a clear, colorless fluid before ejaculation (the release of semen). The fluid cleanses the urethra, protects the sperm from damage, and provides some lubrication for intercourse
This duct is formed by the union of the vas deferens with the duct of the seminal vesicle. They pass through the prostate, and open up into the urethra at the seminal colliculus. During ejaculation, semen passes through the prostate gland, enters the urethra, and exits the body through the urinary meatus
A long, coiled tube that rests on the top and side of the testes. It stores and then transports sperm cells to the vas deferens
Oval or almond-shaped male sex glands that produce sperm and male hormones. The two main types of cells in these glands are germ and stromal cells
The upper section of the uterus that is connected to the fallopian tubes
The rounded mass of fatty tissue that lies over the joint of the pubic bone, located at the front of the vulva
The male hormone, which is produced in the testes. This hormone is needed for reproductive organ function. It is also needed for the development of the male secondary sex characteristics
A group of steroid hormones that promote the development and maintenance of female characteristics of the body. These hormones can also produced artificially for use in oral contraceptives, to treat menopausal as well as menstrual disorders.
Consists of the external female genitalia (labia, clitoris, etc.)
The process in which the lining of the uterus breaks up and is discharged from the body through the vagina. This cycle occurs about very twenty-eight days
The nipple is a raised region of tissue on the surface of the breast, which is surrounded by the areola. In women who are pregnant or have given birth, they can produce breast milk through the nipple's lactiferous ducts. The milk can flow through the nipple passively or it can be ejected by smooth muscle contractions that occur along the ductal system
Labia _, otherwise known as the inner labia lips. They are thin, pigmented, hairless flaps of tissue located inside the outer lips
Sac-like vesicles that attach to the vas deferens near the base of the bladder. They produce a sugar-rich fluid that provides sperm with a source of energy to help them move
Two almond-shaped glands which are located on either side of the uterus in the abdominal cavity. These glands store your ova (eggs), as well as produce hormones (including estrogen, progesterone, and testosterone). These hormones control things such as periods and pregnancy
A thin external sac of skin that is suspended between the thighs and is divided into two compartments. Each compartment contains one of the two testes and is made up of skin and muscle
Labia _, otherwise known as the outer labia lips. They are hair-covered folds of tissue located behind the mons pubis
A fluid that is emitted from the male reproductive tract which contains sperm cells (which are capable of fertilizing the female ovum)
