Reproductive System Flashcards
Functions of the reproductive system
Production of gametes (sex/germ cells)
Store gametes
Nourish gametes
Transport gametes
Functions of female reproductive system
Provide nutrient and support to developing embryo, fetus, and infant
Fertilization
Fusion of male and female gametes to form a zygote (fertilized egg)
NUCULI ARE GOING TO FORM TOGETHER
What are the organs of the reproductive system
Gonads (testes, and ovaries)
Cuts
Accessory glands and organs
External genitalia
Function of Gonads
Produce sperm/egg
Testes produce ____
And secrete ____
Testes produce spermatozoa
And secrete testosterone
How many oocytes do ovaries release a month
One
What hormones do ovaries secrete
Estrogen
Progesterone
What is the function of ducts
A passageway that opens to the exterior and transport gamete
What does sperm do when it is along the ducts
Sperm mixes with secretion of accessory glands and then convert to semen
Oocyte travels along
Uterine tube (duct) (Fallopian tube) to uterus
Accessory glands and organs
Secrete fluid
Seminal vehicle secrete seminal fluid
Secondary sex characteristics that develop at puberty in both sexes
Pubic and auxiliary hair and their associated scent glands, and the pitch of voice
Male secondary’s sex characteristics
Facial hair
Coarse and visible hair on the torso and limbs, relatively muscular physique
Female secondary sex characteristics
Distribution of body fat, breaker enlargement, and relatively hairless appearance of the skin
Tunica vaginalis
Covers each testis
Tunica albuginea
White coat on testes
Septum created from tunica albuginea divides testes into
250 to 300 wedge shaped lobules
Seminiferous tubules
Ducts where sperm are produced
Seminiferous tubules contain
Spermatozoon is (stem/germ cell)
Spermatogenesis
Production of sperm cells
Spermatocytes go through meiosis I and meiosis II and make 4 spermatic
functions of Sustentacular (serotonin) cells
- Protect germ cells and stimulate development
2. Provide nutrients, waste removal, growth factors etc to germ cells
Interstitial (leadings) cells
Produce testosterone
Sperm passageway
‘SEVEN UP’
Seminiferous tubules
Epididymis
Vas/ ductus deferents (and seminal vesicular)
Ejaculatory duct
N/A
Urethra
Penis
What are the accessory organs of male reproductive system
Seminal vesicles
Prostate gland
Bulbourethral glands
Scrotal sac encloses testes
Spermiogenesis
Spermatic differentiate into spermatozoa (physical maturation of sperm)
ACTUAL MOBILE SPERM FORMATION
Changes that transform spermatids into spermatozoa
Discarding excess cytoplasm and growing tails
Head of spermatooon
Nucleus and densely packed chromosomes
Middle piece of spermatozoon
Mitochondria that produce the ATP needed to move the tail
Tail of spermatozoon
The only cell with flagellum in the human body
It enables the spermatozoa to swim
Blood testis barrier (BTB)
Formed by tight junctions between sustentacular cells
Separates sperm from immune system
Prevents antibodies from getting to the germ cells
Germ cells would be attacked by the immune system
