In males the penis and urethra belong to both the urinary system and reproductive system. The testes are carried in an external pouch that is more commonly known as the scrotum. They actually remain at a slightly cooler temperature than normal body temperature so that they are able to facilitate sperm production. 1…

    Female Reproductive System Essay

    The aim of the female reproductive system is to produce mature oocytes which match with the male spermatocyte to create offspring. Fertilisation most commonly occurs in the fallopian tubes, though this can also occur later in a female’s menstrual cycle if the egg has already moved down into the uterus, though there is a higher chance of miscarriage as the lining of the womb may continue to shed. The external female reproduction features have two functions; to allow insemination and to also protect against infection and injury. These structures include; the labia majora, which contains glands that produce sweat, the labia minora which surrounds the opening of the vagina and urethra, bartholin's glands which are just behind the vaginal…

Gametes are haploids which is the only type of cell that contains only one set of chromosomes.

    P3: Outline the main gross structure of the body system

    The scrotums function is to produce millions of male sex cells (sperm) and to make male sex hormones which affect the way a man’s body develops. The sperm produced by the scrotum then passes through the sperm ducts and mixes with fluids produced by the glands. The tube inside the penis that carries urine or semen is called the urethra; these two fluids can’t be mixed up due to a ring of muscle which prevents it from happening. The function of the penis is to pass urine out of the body and also pass semen into the woman’s vagina during sexual intercourse.…

    Ductus deferens- (also known as the vas deferens) is continuous with the epididymis within the scrotal sac. It travels upward through the scrotum and continues through the inguinal ring into the abdominal cavity. The spermatic cord is composed of a connective tissue sheath that encloses the ductus deferens, arteries, veins, nerves, and lymph vessels as it ascends up through the inguinal canal. In the abdominal cavity, the ductus deferens travels up, over, and behind the bladder. Posterior to the bladder the ductus deferens joins the seminal vesicle to form the ejaculatory duct…
