White blood cells

The immune system contains cells specialized in fighting pathogens. The first line of defense is your skin. Skin covers most of your body, so it is only fitting that it be the toughest. Because of how closely packed skin cells are, and the fact that they are always moving toward the surface, makes it very hard for pathogens to get in. Your second line of defense is made of organs like your nose and your stomach. Your third line of defense is made up of lymphocytes. White blood cells are the basic cell, almost like a soldier. Also known as phagocytes, they eat pathogens and infected tissue. It will eat, even if it cannot ingest what it is eating. Next, a macrophage, almost like a tank, comes if the phagocytes are not enough. It can catch and digest many more pathogens than a phagocyte. If this is not enough, a T-cell, a specialized cell, docks and extracts an antigen, a special part of a pathogen. It analyzes the antigen, and sends a, message to the B-cell, another lymphocyte. B-cells take the antigen, and build antibodies, special proteins in the shape of a Y, to lock with it (that’s why you eat your protein, folks). When the
antibodies are released, they are launched at the pathogens, and can immobilize or even destroy

them

What's wrong with the body, mama

Germs livin' like they ain't got no mamas

I think the whole body’s addicted to the drama

Only attracted to things that'll bring it trauma

With medicine, yeah, we try to stop terrorism

But we still got terrorists here livin'

In the body, the big ISA

The HIV and The Cold and the ‘fluenza

But if you only have no love for your own body

Then you only leave space for malady

And malady only generates hate

And when you hate then you're bound to get irate, yeah

Madness is what you demonstrate

And that's exactly how a germ works and operates

Man, you gotta have WBC just to set it straight

Take control of your mind and meditate

Let your lymphocyte gravitate to the germ, y'all, y'all

Germs a-killin', tissues dyin'

Cells hurt and you hear them cryin'

Can you protect from the breach

And would you turn the other cheek



Thymus, Thymus, Thymus help us

Send some lymphocytes from above

'Cause people got me, got me questionin'

Where is the White blood? (blood)



Where is the blood?(The blood)

Where is the blood? (The blood)

Where is the blood?

The blood, the blood.



It just ain't the same, always unchanged

New days are strange, is the world insane

If WBC and skin is so strong

Why are there things that don't belong?

Nations droppin' bombs

Chemical gasses fillin' lungs of little ones

With ongoin' sufferin' as the youth die young

So ask yourself is the virus really gone

So I could ask myself really what is goin' wrong

In this world that we livin' in people keep on givin'

in

Makin' wrong decisions, only thing left o’ them is dividends

Not respectin' each other, deny thy brother

A war is goin' on but the its under the skin

If the truth is kept secret, it's swept under the rug

If you never tell the truth then you never know life.
