Inguinal HerniaWhat is it called when the intestines push through the inguinal canal and enter the scrotum?Testis Make sperm cellsEpididymis Series of hollow tubes hat store mature sperm cellsDuctus Deferens When a male ejaculates, sperm cells travel from the epididymis through the ductus deferens into the urethraSeminal vesicleEjaculatory DuctUrethra Transports urine and spermBulbourethral GlandProstate GlandPenis Mostly made up of spongey tissue called the corpora cavernosa and corpora spongiosumGlans Sometimes called the head Cover by a layer of skin called the prepuce or foreskin Circumcision is the practice of cutting off the foreskinBladder Sotres urine formed in the kidneyKidneySpermatic cord1. Ductus Deferens 2. Testicular Artery 3. Testicular VeinWhat is the spermatic cord made of?Ovary Make oocytesUterine Tube/Fallopian Tube transports ovulated oocytes from the ovary to the uterus, if sperm cells are present, fertilization will occurInfundibulumFimbriaeUterus If fertilization has occurred, the zygote will implant in the uterusMyometrium - generate more force per cell than any other muscle in the body Endometrium - lines the uterusWhat two kinds of tissue make up the uterus?MyometriumEndometrium1.
