What’s In
The endocrine system is composed of glands
that secrete different types of hormones that affect
almost every cell, organ, and function of our body. It is
essential in regulating growth and development,
metabolism, as well as reproductive processes, and
mood. Endocrine glands secrete chemicals known as
hormones into the bloodstream, which carries them
throughout the body.
Hormones are chemical messengers, carrying
instructions to cells to change their activities. When a
hormone in the blood reaches the target organ, it
produces a notable effect. The effect of hormones can
last for hours, days, weeks, or even years. The glands
of the endocrine system produce hormones.

A gland is an organ in which cells secrete materials to be brought to the
different regions of the body, sometimes via tube-like structures called ducts.
Endocrine glands (endo mean “within,” krinein means “separate,” i.e., to secrete)
are ductless glands that secrete hormones directly into either the bloodstream or
the fluid around the cells or tissues that secrete hormones.

The Role of Hormones in Male and Female Reproductive Systems
Hormones play a very vital role in the
Female and Male Reproductive Systems.
The normal functioning of the male
reproductive system is due to the
hormones of the pituitary gland. These are
the follicle-stimulating hormone (FSH)
and the interstitial cell-stimulating
hormone (ICSH). Under the influence of
FSH, the seminiferous tubules of the testes
become active and start producing sperms.
The ICSH stimulates a group of cells called
the interstitial cell, surrounding the
seminiferous tubules to produce hormone
testosterone.
Once testosterone is produced, the
entire male reproductive system becomes active. Secondary sex
characteristics become evident in the adolescent boy. Among the secondary
sex characteristics are the growth of a big muscular body, a booming voice,
and the growth of mustache, beard, and hair in certain areas of the body.
Aside from its role in developing secondary sex characteristics,
testosterone also suppresses or limits the production of FSH by the pituitary.
The female reproductive system, just
like the male reproductive system, is also
regulated by hormones. In the female, a
close relationship exists among the
pituitary, ovary, and uterus. Upon reaching
the age of 12 to 16, the anterior lobe of the
pituitary starts secreting a hormone called
follicle-stimulating hormone (FSH). This
hormone controls the growth and release of
eggs from the ovaries. Estrogen is the
reproductive hormone in females that
assists
in
endometrial
re-growth,
ovulation, and calcium absorption; it is
also responsible for females' secondary
sexual characteristics.
These include breast development,
flaring of the hips, and a shorter period necessary for bone maturation,
menstruation, and fertility. Progesterone assists in endometrial re-growth
and inhibition of follicle-stimulating hormone and luteinizing hormone
5
release. While other hormones prepare the uterus so a baby can grow in it,
other hormones still control the stretching of the uterus during pregnancy.
From the hormones listed above, the next activity will focus on the role
of these hormones in the Male and Female Reproductive Systems.

My Final Farewell
Farewell, dear Fatherland, clime of the sun caress'd
Pearl of the Orient seas, our Eden lost!,
Gladly now I go to give thee this faded life's best,
And were it brighter, fresher, or more blest
Still would I give it thee, nor count the cost.
Let the sun draw the vapors up to the sky,
And heavenward in purity bear my tardy protest
Let some kind soul o 'er my untimely fate sigh,
And in the still evening a prayer be lifted on high
From thee, 0 my country, that in God I may rest.
On the field of battle, 'mid the frenzy of fight,
Others have given their lives, without doubt or heed;
The place matters not-cypress or laurel or lily white,
Scaffold or open plain, combat or martyrdom's plight,
T is ever the same, to serve our home and country's need.
Pray for all those that hapless have died,
For all who have suffered the unmeasur'd pain;
For our mothers that bitterly their woes have cried,
For widows and orphans, for captives by torture tried
And then for thyself that redemption thou mayst gain
I die just when I see the dawn break,
Through the gloom of night, to herald the day;
And if color is lacking my blood thou shalt take,
Pour'd out at need for thy dear sake
To dye with its crimson the waking ray.

My dreams, when life first opened to me,
My dreams, when the hopes of youth beat high,
Were to see thy lov'd face, O gem of the Orient sea
From gloom and grief, from care and sorrow free;
No blush on thy brow, no tear in thine eye.

Dream of my life, my living and burning desire,
All hail ! cries the soul that is now to take flight;
All hail ! And sweet it is for thee to expire ;
To die for thy sake, that thou mayst aspire;
And sleep in thy bosom eternity's long night.

If over my grave some day thou seest grow,
In the grassy sod, a humble flower,
Draw it to thy lips and kiss my soul so,
While I may feel on my brow in the cold tomb below
The touch of thy tenderness, thy breath's warm power.

I Am a Filipino, by Carlos P. Romulo
I am a Filipino–inheritor of a glorious past, hostage to the uncertain
future. As such I must prove equal to a two-fold task–the task of
meeting my responsibility to the past, and the task of performing
my obligation to the future.
I sprung from a hardy race, child many generations removed of
ancient Malayan pioneers. Across the centuries the memory comes
rushing back to me: of brown-skinned men putting out to sea in
ships that were as frail as their hearts were stout. Over the sea I see
them come, borne upon the billowing wave and the whistling wind,
carried upon the mighty swell of hope–hope in the free abundance
of new land that was to be their home and their children’s forever.
I am a Filipino. In my blood runs the immortal seed of heroes–seed
that flowered down the centuries in deeds of courage and defiance.
In my veins yet pulses the same hot blood that sent Lapulapu to
battle against the first invader of this land, that nerved Lakandula
in the combat against the alien foe, that drove Diego Silang and
Dagohoy into rebellion against the foreign oppressor.
The seed I bear within me is an immortal seed. It is the mark of my
manhood, the symbol of dignity as a human being. Like the seeds
that were once buried in the tomb of Tutankhamen many thousand
years ago, it shall grow and flower and bear fruit again. It is the
insignia of my race, and my generation is but a stage in the
unending search of my people for freedom and happiness.
14
I am a Filipino, child of the marriage of the East and the West. The
East, with its languor and mysticism, its passivity and endurance,
was my mother, and my sire was the West that came thundering
across the seas with the Cross and Sword and the Machine. I am of
the East, an eager participant in its spirit, and in its struggles for
liberation from the imperialist yoke. But I also know that the East
must awake from its centuried sleep, shake off the lethargy that has
bound his limbs, and start moving where destiny awaits.
I am a Filipino, and this is my inheritance. What pledge shall I give
that I may prove worthy of my inheritance? I shall give the pledge
that has come ringing down the corridors of the centuries, and it
shall be compounded of the joyous cries of my Malayan forebears
when first they saw the contours of this land loom before their eyes,
of the battle cries that have resounded in every field of combat from
Mactan to Tirad Pass, of the voices of my people when they sing:
“I am a Filipino born to freedom, and I shall not rest until freedom
shall have been added unto my inheritance—for myself and my
children and my children’s children—forever.”
