What the the types of ducts in the male reproductive system 1. epididymus 2. Vas deferens 3. ejaculatory duct 4. urethra
________ Receives sperm from seminiferous tubules it is the Site of sperm maturation and it Takes 10-14 days for sperm to pass through the tube Epididymus
___ _____Extends from epididymus, through inguinal canal, enters pelvic cavity,runs along lateral surface of bladder, Uses peristalsis to move sperm Vas deferens

_______ _______ hormone - works with testosterone to stimulate spermatogenesis Follicle-stimulating
________ hormone - Promotes growth of interstitial cells and Stimulates production of testosterone by interstitial cells Luteinizing
What are the functions of testosterone in males 1. Promotes the formation of male sex organs in fetal development 2. Promotes maturation of male reproductive organs and the development of male secondary sex characteristics during puberty
What are the male secondary sex characteristics 1. Growth of body hair 2. Increased muscular development 3. Development of heavy bones, broad shoulders, and narrow pelvis 4. Deepening of the voice 5. Increase in rate of cellular metabolism 6. Increase rate of red blood cell production
What are the functions of the female reproductive system. *Produces female sex hormones and sex cells(eggs) *Transports eggs to site where they can meet sperm *Provides environment for development of offspring *Helps facilitate the birthing process *Supplies offspring with nutrients after birth
Describe the ovaries 1. Upper lateral portions of pelvic cavity 2. Size and shapes of almonds 3. Outer surface is covered by a germinal epithelium
During ________(ova production)All germ cells divide and become primary oocytes prior to birth, Females are born with their total number of primary oocytes Oogenesis
Primary ____ do not activate until puberty and only a few are activated and only one is released oocytes
Describe the uterine tubes 1. Extends from ovary to the uterus 2. Possesses fimbria to create current in surrounding fluid to sweep egg into tube 3. Inside lining possesses ciliated columnar epithelium that draws the ovum into the tube and propels it toward the uterus
What are the 3 layers of the uterus 1. Endometrium - Lines interior 2. Myometrium - Smooth muscle 3. Perimetrium - Covers the exterior surface
Describe the uterus 1. Posterior to bladder but bends over and above bladder 2. Hollow organ with thick muscular walls 3. Provides an appropriate internal environment for a growing baby
