taken place—to bind with a substance that has not yet been manufactured?
How do they know the formula for an enzyme that will convert one mole-
cule into another? No doubt is the incomparable God Who inspires this
knowledge in the lung cells.
The enzyme angiotensin-II has two vital functions; first, to ensure the
constriction of the blood vessels. Angiotensin-II stimulates the muscles
around the blood vessels and sets the mechanism that provides the con-
traction—yet another proof of flawless creation. The muscles are thus con-
tracted, the diameter of the blood vessels is reduced and blood pressure is
elevated. This is the first intended outcome.

The second major duty of angiotensin-II is to call to duty the miracu-
lous hormone aldosterone. When the angiotensin-II reaches the adrenal
cells, it commands them to secrete aldosterone. This is yet further proof of
the flawless nature of the allover blueprint, because the aldosterone will af-
fect the kidneys, causing them to re-absorb the water in urine and release
that water back into the bloodstream. In this way, the volume of blood will

Figure 44.
Angiotensin II reaches the adrenal cells above the kidneys and commands them
to secrete aldosterone. This affects the kidneys, causing them to re-absorb
water from the urine and release it back into the bloodstream. This results in an
increase in blood pressure. This magnificent plan functions absolutely flaw-
lessly and is a manifestation of the omniscience of God.
