Puberty Flashcards
Puberty
the start of the body’s transition into becoming an adult
-hormones are triggered (estrogen, progesterone)
-5 stages
-at the end, sexual maturity is reached and you can reproduce
When do boys start puberty
ages 9-14
-2 yrs later than girls
Male Puberty: Stage 1
Prepubertal, no visible changes
Male Puberty: Stage 2
-physical changes begin
-genital development
-hair growth around groin + underarms
-height increase (abt 2 in a yr)
-growing pains
Male Puberty: Stage 3
-physical changes speed up (age 10-16)
-height increase (abt 3 in a yr)
-sweating

What type of organs does mens reproductive system have
internal and external
penis
the organ that urine and sperm (seminal fluid) go through the outside of the body
Foreskin
a loose fold of skin covering the head of the penis. It may be removed during a surgical procedure called circumcision
Testicles
2 walnut-sized organs that make sperm cells. The sperm unites with an egg from a woman for a baby to form
Scrotum
the sac located on the outside below the penis that holds the testes (temperature controlled)
Urethra
the tube that goes from the urinary bladder through the penis to the outside
Vas deferens
the tube that carries sperm from the testes to the urethra. Sperm move through the penis to the outside during ejaculation
Prostate gland
a gland that is inside the body at the base of the urethra. It secretes fluid that helps sperm move more easily
Rectum
butt
Seminal gland
the glands are important to reproduction since they produce seminal fluid and act with other body parts to push semen out during ejaculation
Cowper’s Gland (Bulbourethral glands)
pea-sized structures that produce a clear, slippery fluid that empties into the urethra. The fluid lubricates the urethra and neutralizes acidity that may be present from residual urine. Cannot reproduce without it
epididymis
long, coiled tube that rests on the back of each testicle. It carries and stores sperm cells that are created in the testes. Also brings sperm to maturity (the sperm that come from the testes are immature)
bladder
hollow organ that stores urine
Women’s reproductive system
-contains internal and external organs
-Creates hormones
-responsible for fertility, menstruation, and sexual activity
Cervix
the lowest part of the uterus. A hole that allows the sperm to enter and menstrual blood to exit. It opens up (dilates) to allow a baby to come out during a vaginal childbirth
Uterus
is a hollow pear-shaped organ that holds a fetus during pregnancy
Ovum
small, oval-shaped glands located on either side of the uterus. They produce eggs and hormones
fallopian tubes
narrow tubes that are attached to the upper part of your uterus and are pathways for your ovum to travel from the ovaries to the uterus. Fertilization of an egg by sperm normally occurs in the fallopian tubes. The fertilized egg then moves to the uterus, where it implants into your uterine lining
fimbriae
finger-like projections on the ends of your fallopian tubes closest to your ovaries. Each month, your fimbriae catch the egg that one of your ovaries releases during ovulation. You fimbriae then sweep the egg (ovum) into the fallopian tube where the egg can be fertilized
uterine lining
preparation for implantation, maintenance of pregnancy if implantation occurs and menstruation in the absence of pregnancy
ovary
produce and store your eggs (ovum) and make hormones that control your menstrual cycle and pregnancy
vagina
provides a passageway for blood and mucosal tissue from the uterus during a woman’s monthly period
