Document Summary
Production of gametes: sperm cells in males and oocytes (eggs in females) Function as endocrine glands: production of hormones wide range effect on other tissues. Male reproductive structures urethra serves two physiological functions in males: urinary and reproductive. 0. 01% of sperm make it to secondary oocyte. Tunica albuginea divides testis into lobules; connective tissue; continuous to interior part of gland and separates it into lobules. Seminiferous tubule: secrete testosterone, site of sperm and hormone production: convoluted tube maximizes sa to maximize cells that make sperm, fusing of tubules into tubulus rectus moves into efferent ductules. Tubulus rectus is a merging of tubule network from each lobule. Epididymis: extension of very long tubule network; comma shaped organ stage of sperm maturation. Before sperm cells enter the epididymis, they would not be able to fertilize oocyte; not mature. Sperm cells leave epididymis andmove into ductus deferens (vas deferens) sperm cells mature.
