Abstract
We've now unlocked some of our body's incredible secrets for rapid response to the ever-changing threat from microbe invaders. "The life of the flesh is in the blood" (Leviticus 17:11). What we know today confirms what God taught the Israelites nearly 4,000 years ago. Blood really does sustain life. Red blood cells carry oxygen to body tissues. The liquid portion of blood, plasma, carries water and nutrients to nourish cells, while carrying away harmful wastes from their activities. Other cells in the blood (white blood cells) defend us from constant intrusion and attack by bacteria, viruses, fungi, protozoa, and even microscopic invertebrates. These potential intruders are sometimes collectively called microbes.
