lesson 1 Flashcards
The biological system made up of all anatomical organs involved in sexual reproduction.
Reproductive System (Genetal System)
• Produces male gametes (sperm cells)
• Transfer them to the female
Male Reproductive System
• Produces female gametes (egg cells/ovum)
(singular: ovum plural: ova)
• Receives male gametes
• Carries the baby throughout it’s develop
Female Reproductive System
Regulates the temperature of the testes
Scrotum
At what temperature does sperm form best at?
35°C
Deposits the sperm into the vagina during mating
Penis
Hangs behind the penis and contains the testicles. It acts as a climate control system for the testes.
Scrotum
Responsible for making testosterone and producing sperm cells
Testis
A long, coiled tube that rests on the back side of each testicle. It carries, stores, and brings the sperm to maturity.
Epididymis
It transports mature sperm to the urethra in preparation for ejaculation
Vas Deferens
Vasectomy
Formed by the fusion of the vas deferens and the seminal vesicles
Ejaculatory Duct
Carries urine from the bladder to outside of the body
Urethra
Produces a sugar-rich fluid (fructose) that provides sperms with a source of energy and help with the sperm’s motility (ability to move)
Seminal Vesicle
A walnut like structure which contributes additional fluid to the ejaculate, and help nourish the sperm
Prostate Gland
• Also called the 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
Cowper’s Gland
Site of oogenesis; produces hormones estrogen and progesterone
Ovary
Production of sperm cells
Spermatogenesis
Picks up ovum from the ovary
Fimbriae
Passage from ovary to uterus; site of fertilization
Fallopian Tube (Oviduct)
Nourishes the embryo ; sheds during menstruation
Endometrium
Site of egg implantation; embryo development
Uterus
Muscular opening of the uterus
Cervix
Entrance of the penis; also called the birth canal
Vagina
Pathway of the sperm
- Vagina
- Cervix
- Uterus
- Fallopian Tube
Chemical messengers of the body. They are important to maintain homeostasis
Hormones
MALE:
Signals sperm production (spermatogenesis)
Follicle-Stimulating Hormone (FSH)
MALE:
Stimulates production of testosterone
Luteinizing Hormone (LH)
• Most important male hormones
• Responsible for regulating sex differentiation
Testosterone
FEMALE:
Signals development of egg cells
Follicle-Stimulating Hormone (FSH)
FEMALE:
Plays a role in the development of ova, and stimulation of estradiol and progesterone production
Luteinizing Hormone (LH)
• Instrumental in breast development , fat distribution in the hips, legs, and breasts.
• Secreted by ovaries PRIOR to ovulation
Estrogen
• Helps prepare the body for potential pregnancy
• Secreted by ovaries after ovulation
• If egg is not fertilized, progesterone levels become low and menstruation happens
Progesterone
