GAS 1
Essential for reproduction and in regulating sexual development.
Gonads
Are the primary reproductive organs in males and females, responsible for producing gametes (sperm or eggs) and sex hormones.
Gonads
Include the organs necessary for reproduction in males and females
Primary Sex Characteristics
Are directly involved in reproduction and are present at birth
Primary Sex Characteristics
Delivers sperm to the female reproductive system.
Penis
Produce sperm and male sex hormones (testosterone)
Testes
Involved in sperm production and ejaculation.
Seminal vesicles, Prostate gland, and Vas deferens:
Holds and protects the testes.
Scrotum
Nurtures the developing fetus during pregnancy.
Uterus
Produce eggs (ova) and female sex hormones (estrogen and progesterone).
Ovaries
Transport eggs from the ovaries to the uterus
Fallopian Tubes
receives sperm during intercourse and serves as the birth canal.
Vagina
External characteristics that signal maturation
Secondary Sex Characteristics
Changes are regulated by sex hormones
Secondary Sex Characteristics
Not directly involved in reproduction but distinguish the sexes
Secondary Sex Characteristics
Develop during puberty
Secondary Sex Characteristics
Broadening of shoulders
Male
Increased muscle mass and body size
Male
Growth of facial and body hair (chest, underarm, pubic).
male
Deepening of the voice
male
Uterus and vagina become larger
Ovaries start to release eggs and period begin
Female
Accumulation of body fat, especially around the hips and thighs
Female.
Widening of hips
Female
Growth of body hair (underarm, pubic)
Female
Development of breast
Female
Responsible for the production of offspring and the regulation of sexual functions
REPRODUCTIVE SYSTEM
Carrying messages through your blood to you organs,skin, muscles and other tissues
HORMONES
Are chemical messengers produced by glands in the endocrine system.
HORMONES
first menstrual period of females
Menarche
The average cycle is •• days long;however, a cycle can range in length from •• days to about •• days.
28, 21 to 32
is the hormonal process a woman's body goes through each month to prepare for a possible pregnancy.
menstrual cycle
individuals who possess both ovarian and testicular tissues.
Hermaphrodites/intersex
are formed who are individuals having accessory reproductive structures that do not"match" their gonads.
Pseudohermaphrodites
due to a narrowing of the foreskin of the male reproductive structure and misplaced urethral openings
Phimosis
a condition in which one or both of the testes fail to descend from the abdomen into the scrotum.
Cryptorchidism
The union of sperm and egg, usually occurring in the fallopian tubes,leading to the formation of a zygote.
Fertilization
They are typically located in the scrotum, which helps regulate their temperature.
Testes
The reproductive primary organs male that produce sperm and hormones,primarily testosterone.
Testes
The duct that transports sperm from the epididymis to the ejaculatory duct
Vas Deferens
A coiled tube where sperm mature and are stored after being produced in the testes.
Epididymis
Produces a fluid that helps protect and energize sperm, contributing to semen.
Prostate Gland
Glands that secrete a fluid rich in sugars to nourish sperm and form a significant portion of semen.
Seminal Vesicles
It contains erectile tissue that fills with blood during arousal,facilitating erection.
Penis
The external organ used for sexual intercourse and the delivery of sperm
Penis
Produce a pre-ejaculatory fluid that lubricates the urethra and neutralizes acidity.
Bulbourethral Glands (Cowper's Glands):
The primary female reproductive organs that produce eggs (ova) and hormones, primarily estrogen and progesterone.
Ovaries
The pouch of skin that contains the testes and helps regulate their temperature for optimal sperm production.
Scrotum
Fertilization typically occurs here if sperm is present.
Fallopian Tubes
Tubes that transport eggs from the ovaries to the uterus.
Fallopian Tubes
A hollow, muscular organ where a fertilized egg implants and develops into a fetus
Uterus
uterus has three layers: the endometrium (inner lining), myometrium (muscle layer),and perimetrium (outer layer).
endometrium, myometrium, perimetrium
muscular canal that serves as the birth canal and the receptacle for the penis during intercourse.
Vagina
The lower part of the uterus that opens into the vagina and allows the passage of menstrual fluid and childbirth
Cervix
A It also allows for menstrual fluid to exit the body.
vagina
A small, sensitive organ that plays a significant role in sexual arousal.
Clitoris
The external part of the female genitalia, including the labia majora, labia minora, clitoris, and vaginal opening.
Vulva
