Understanding Human Reproduction The Male and Female Reproductive Systems STRUCTURES OF THE HUMAN REPRODUCTIVE SYSTEM Human Reproductive Male Reproductive Female Reproductive System System System oviducts Testes, scrotum, ducts, Ovaries, oviduct, uterus, penis, seminal visicles, cervix, vagina epididymis, vas prostate glands, deferens, urethra bulbourethral glands  LEARNING OBJECTIVES produce male produces female gametes (sperm gametes (egg cells cells), transfer or ovum), receives them to the female male gametes, carries baby  PROPERTIES OF LIFE The ability to reproduce is one of the most interesting and mysterious attributes organisms. Organisima reproduce to perpetute their kind. Asexually or Sexually  HUMAN REPRODUCTION Carried out through Sexual Reproduction These gametes are This mode of called spermatozoa or reproduction involves sperm cells and ova or the union of gametes. egg cells. These organs are also referred to as gonads or sex glands. The male gonads are the testes, while female gonads are the ovaries. Sperm Cell Egg Cell Nucleus Mitochondria Tail  PRESENTATION THE MALE REPRODUCTIVE SYSTEM ACTIVITY THE MALE REPRODUCTIVE SYSTEM  THE MALE REPRODUCTIVE SYSTEM Parts Function Testis Produces sperm cell Penis Deposits sperms into the vagina Vas deferens Carries sperm from testes to urethra Urethra Carries sperm and urine out of the body  THE MALE REPRODUCTIVE SYSTEM Parts Function Glands Provide liquid in which sperm can swim a. seminal vesicle secretes a fluid that makes up most of the components of the semen b. prostate gland secretes a slightly alkaline milky fluid that is discharged as a part of the semen c. bulbourethral secretes a thick and clear mucus that lubricats and neutralizes the any trace of acidic gland urine in the urethra  ROLE OF THE MALE REPRODUCTIVE SYSTEM The key role of the male reproductive system is to produce sperm cells in the testes and release them inside a female. If a sperm cell successfully reaches an egg cell and fertilization occurs, an embryo will be formed. The embryo will develop into a baby over the course of a pregnancy. The male reproductive system is controlled by hormones.  1 - PENIS The penis is used for both urination and sexual intercourse. It is made of spongy tissue and blood vessels. These blood spaces are relatively empty when the organ is flaccid, but is filled with blood when the penis is erect. The flow of uterine is blocked from urethra in order to allow only semen to pass through during sexual intercourse.  2 - TESTES The male reproductive system has two testes. They are oval-shaped organs located inside the scrotum. They are involved in the production of testosterone, the primary male sex hormone, and in the production of sperm cells or spermatogenesis. Glans  3 - FORESKIN The foreskin is a retractable fold of skin which covers the end of the penis.  4 - SCROTUM The scrotum is a bag of skin which contains the two testes. It acts as a climate control system. provide protection for the testes and aid in the normal development of sperm cells. testes must be at a temperature lower than the body temperature for proper production.  5 - URETHRA The urethra is a hollow tube which transports urine from the bladder to outside the body. It also transports sperm. 6 - SPERM DUCT/VAS DEFERENS The main role of the sperm ducts are to transport sperm away from the testes, where sperm is made. Epididymis is a long coiled tube; 6 meters long, located behind each testis. Store sperm cells that are prodeuce in testis. Sperm cell undergo maturation in epipidymis. 7 - SPERM DUCT/VAS DEFERENS Vas deferens or ductus deferens os another sperm duct that extends upward from epipidymis. It transports mature sperm cells to the urethra in preparation for ejaculation. Ejaculation refers to the discharge of semen through the urethra. Semen is a mixture of sperm cells and various secretions.  8 - BLADDER The bladder temporarily stores urine in the body. It helps expel urine from the body by sending nerve signals to the nervous system which tells the brain that you need to go to the toilet. 9 - PROSTATE GLANDS A walnut-like structure located below the urinary bladder, where it sorrounds the first part of the urethra. 10 - SEMINAL VESICLES produces a thick, yellow, an alkaline secretions rich in a sugar fluid (fructose) that provides sperms with a source of energy and helps with the sperms’ motility (ability to move) they are attched to the vas deferens near the base of the bladder. 11 - COWPER’S GLAND also called Bulbourethral gland, produce a clear slippery fluid that empties directly into the urethra. This fluid serves to lubricate the urethra and to neutralize any acidity due to residual drops of urine in the urethra.  Why is learning about the reproductive system important for understanding our own health, and how does it help us show respect and responsibility toward others in our community? EXIT CARD: 1/4 Write one key takeaway and one question about the male reproductive system that you are uncomfortable asking your parents.
