Reproductive System
Male-
Testes-
Seminiferous tubules- creation of sperm (gamete), influenced under a hormone (gonadotropin) and is a follicle stimulating hormone
Interstitial cells- secreting testosterone under the influence of gondadotrophin in luteinizing hormone. Testosterone maintains the males characteristics and organs
-
-
Spermatic cord- consists of the testicular artery, testicular nerve, venous plexus. The venous plexus absorbs heat from the testicular artery since the testes should stay cool for the sperm
Accessory glands-
Seminal vesicles- secrete nutrients for sperm substances that 1. increase sperm motility 2. suppress female immune system 3. clot semen (semen is sperm and secretion from glands), then liquefy it (happens within the vagina). The prostate glands add to number 1 and 3
Bulbo-urethral gland- secretes alkaline mucus, neutralizes acidity of urethra and lubricates the urethra (this happens slightly before ejaculation of semen, the scrotum protects testes and cools them down)
Prostate gland- secretes prostate fluid which is one of the components of semen. The muscles help propel the seminal fluid into the urethra during ejaculation
Corpus cavernosum- smooth muscle, connective tissue and vascular spaces

-
Female-
-
Uterine tube-
Passageway for ovum, sperm, fertilized egg which then becomes a zygote/embryo
-
-
Uterus- has three layers
-
2. Myometrium- muscle, thick and contracts during childbirth
3. Endometrium- mucous layer: functional layer builds up during menstrual cycle (approximately 28 days), it then sheds (approximately 1-5 days). Basal layer is deep to the functional layer, does not shed, responsible for formation of functional layer
