serve to carry the genomic information from cell to cell
chromosomes
single set of chromosomes in an organism's cell
haploid
two complete sets of chromosomes, one from each parent
diploid or somatic cell
an oval-shaped organ inside the protective sac of the skin
testes
protective sac of skin of the testes
scrotum
this is the needed temperature of the testes/scrotum to properly produce sperm lower than the body temperature
1 to 3 degrees
a clusters of hundreds of compartments w/ many tiny coiled tubes inside the testes
seminiferous tubules
stimulates secretion of sex hormone testosterone
luteinizing hormone (LH)
along w/ testosterone, stimulates sperm production in the seminiferous tubules
follicle-stimulating hormone (FSH)
this is produced by Leydig cells, found between the seminiferous tubules, responsible for secondary male characteristics
testosterone
where sperm cells mature after being produced by seminiferous tubules
epididymis
where sperm cells travel after being mature to the epididymis
vas deferens
where sperm cells exits the body, a larger tube which urine passes and exits the body
urethra
parts of sperm: it contains the chromosomes, made of nucleus
head
parts of sperm: contains mitochondria
midpiece
parts of sperm: responsible for the sperm's movement, powerful flagellum enable the sperm call to move
longtail
where sperm cell head are made of
nucleus
a cap of a head of sperm cells, stores the enzymes needed to penetrate an egg cell
acrosome
contains mitochondria that supply the energy needed
maprece
it closes the urinary tract, allows the sperm to exit the body
prostate gland
fluid rich in sugars, sperm cell use it for energy
seminal vesicles
alkaline fluid neutralizes traces of acidic urine in the urethra
bulbourethral glands
through ejaculation sperm exits the penis, sperm swim to encounyter the egg cell
ejaculation
how many semen expelled during ejaculation
3.5 milliliter
how many sperm cell produced during ejaculation
300 to 400 million
how many sperm cell in just one drop
5 to 10 million
its responsible for developing female sexual characteristics
estrogen
what is the term for first menstrual period, that occurs between the age 10 to 16, average of onset 12.4 years
menarche
it reduces the number of chromosomes in gametes
meiosis
its responsible for reproducing eggs
ovaries
egg cell starts to mature around and 11 to 14 years old
11 to 14 years old
its a process of fertilization occur, female reproductive system will began to nourish and protect the fertilized egg during nine months of development
gestation or pregnancy
how many egg cells females have after they're born
2 or two million eggs
number of egg cells would have gone down to about 400,000 during this stage
puberty
how many chromosomes does egg cell contain
23 chromosomes
how many egg cell will only mature
300 to 500 egg cell
what do you call a mature egg cell
ova or ovum
how many days does ova released from the ovary of an adult female
28 days
it sweep the ovum travel inside the fallopian tubes
cilia
how many days ovum travel inside the fallopian rube?
