Human Reproductive Systems

Human Reproductive Systems We will be studying both the male and female reproductive systems. All males have the same physical body parts for reproduction as other males. All females have the same physical body parts for reproduction as other females. We will be looking at drawings of the male and female reproductive systems. We will learn and use accurate terms for male and female body parts – not slang words.

Female Reproductive System

Female: Internal View

Female Internal View Vagina: The muscular, hollow, tube-shaped organ that extends from the vaginal opening to the uterus Functions: Sexual intercourse The pathway that a baby takes out of a woman’s body during childbirth The route for the menstrual blood (the period) to leave the body from the uterus

Female Internal View Cervix Uterus (womb) The part of the uterus that opens into the upper part of the vagina Has a very small hole that dilates (opens) only when a woman is giving birth Uterus (womb) Shaped like an upside-down pear; has a thick lining and muscular walls Functions: Expands and contracts to accommodate a growing fetus Helps push the baby out during labor

Female Internal View Fallopian tubes Ovaries Connects the uterus to the ovaries Ovaries Two oval-shaped organs that lie to the upper right and left of the uterus Produce, store and release eggs into the fallopian tubes (ovulation)

Female: External View

Female External View The clitoris, a small sensory organ, is located toward the front of the vulva where the folds of the labia join. The urethra is the canal that carries urine from the bladder to the outside of the body. The labia are the inner and outer lips that surround the vaginal opening. The anus is the opening through which solid waste (feces) passes through the body.

Male Reproductive System

Male: Front View

Male Reproductive System Penis Made up of spongy tissue that can expand and contract Made up of two parts: The shaft (the main part of the penis) The glans (the tip, sometimes called the head) At the end of the glans is a small slit or opening, which is where semen and urine exit the body through the urethra

Male Reproductive System Testicles Produce and store millions of tiny sperm cells Scrotum A pouch-like structure outside the body Helps to regulate the temperature of the testicles, which need to be kept cooler than body temperature to produce sperm

Male Reproductive System Seminal vesicles are sac-like structures attached to the vas deferens, to the side of the bladder Vas deferens A muscular tube that passes upward alongside the testicles Transports the sperm-containing fluid called semen The epididymis is a set of coiled tubes (one for each testicle) that connects to the vas deferens.

Male Reproductive System Prostate gland Produces some of the parts of semen Surrounds the ejaculatory ducts at the base of the urethra, just below the bladder Urethra The channel that carries the semen to the outside of the body through the penis The channel through which urine passes as it leaves the bladder and exits the body

Male Reproductive System The bladder is the organ that collects and stores urine produced by the kidneys. Foreskin A fold of skin at the end of the penis covering the glans Some males have a circumcision, which means that a doctor or clergy member cuts away the foreskin
