Q

produces an alkaline fluid which protects sperm

A

prostate gland

17
Q

composition of semen

A

sperm + lubricating fluid from cowper’s gland + alkaline fluid from prostate gland

18
Q

route of sperm from production to ejaculation (and what each organ does)

A

seminiferous tubules (sperm production) -> epididymis (sperm storage) -> vas deferens -> seminal vesicle (secrete sugars) -> prostate gland (alkaline fluid) -> cowper’s gland (lubricant) -> urethra

19

keeps the testicles suspended and away from body heat

A

scrotum

20
Q

connects each nurse cell to over 150 sperm cells throughout the tubule; enable nurse cells to feed and protect maturing sperm

A

tendrils

21
Q

give 5 causes of sperm deformity

any of these: slight elevation of temperature, environmental conditions, overcrowding, stress, smoking, chemical pollution of air and water, occupational hazards, radiation, poor nutrition, modern clothing

22
Q

silent languages

A

desire and physical love (eyes, skin)

23
Q

barriers to fertilization

high percentage of defective sperm has lowered odds of fertilization, acidic environment of vagina, femal immune system will destroy them, try to ertilize the first round object they find

24
Q

this is secreted by the cervix during ovulation which provides tiny channels directing the spem to egg

A

mucin

(what week) can the fetus bring its hands together and suck its thumb?
