Male and Female Reproductive System

1-7 (male) 8-16 (female)

Corpora Cavernosa

2 circular chambers that run the length of penis. Contains thousands of chambers that fill with blood that allow an erection to occur

Penis

External male erectile organ filled with spongy cavernous tissue, arteries, veins, and smooth muscle. Urine and semen leave the both through its urethra. Develops from the same embryonic tissue as the clitoris.

Urethra

A narrow fibromuscular tube that carries urine from the bladder and semen from the ejactulatroy ducts. When erect the flow of urine is blocked.

Glans Penis

The rounded head of the penis in which the urethra exits. Covered with a thin skin layer at birth

Testicle

(Gonads/Testis) Male sex glands, located behind the penis within the scrotal sack. Testicles produce and store sperm. Also, the main source of the male hormone, testosterone. 

Epididymis

On top of the testacle and stores sperm

Spermatic Cord

The tube that contains the vas deferens, penile artery, vein, lymphatic tissue, and nerves connects the testes to the abdominal cavity by way of the inguinal canal. 

Clitoris

small, highly sensitive erectile tissue with over 8,000 nerve endings that develops from the same embryonic mass of tissue as the male penis.

Urethra

opening where urine leaves the body

Vagina

External opening of the female reproductive system. Receives the penis during sexual intercourse, exit for menstrual flow during menstruation and exit during childbirth.

Cervix

The lower narrow neck of the uterus. Dilated to allow out of the uterus. Uterus

Uterus

Hollow, upside down pear shaped organ with thick fibrous walls located in the female’s lower abdomen between the bladder and rectum.

Endometrium

Mucous membranes lining of the uterus, regulated by hormones. Thickens during the menstrual cycle in preparation for the possible implantation of an embryo. 

Fallopian Tube

Thick hollow tube or oviduct that extends from the top of the uterus down to the ovary. Most fragile part of the female body.

Cilia

Microscopic finger like projections on the internal linkin of the fallopian tubes help transport fertilized egg to uterus

Fimbriae

Finger like branches that extend off the end of the fallopian tube into the pelvic cavity. When the egg is released from the ovary these branches pick it up for transport.
