In ancient cultures, people understood the importance of blood. God reminded the people of Israel, “The life of every creature is its blood” (Leviticus 17:14). Today, we understand the significance of this truth even more deeply.
There are no cells in the human body that can live without continual contact with life-giving blood.
Every type of cell, from the ones that survive only moments to those that live for many years, owes its life to the flow of blood. In our study, we’ll examine three types of cells in human blood: red cells, white cells, and platelets.
Each of these performs functions that are essential to life. The red cells nourish every other cell in our bodies with oxygen and other nutrients, and they carry away the toxins our cells create. The role of white cells is surveillance and defense. They are our valiant protectors, continually killing harmful microbes and rushing to the site of any breech in our defenses. Platelets form clots to plug up any breaks in our membranes to stop the bleeding and keep us alive.
The circulatory system is the epitome of consistency. Every day, the heart beats 100,000 times, and over an average lifespan, this amazing machine beats 2.5 billion times, pumping 60 million gallons of blood. During this time, the heart never takes time off. We can’t afford for it to take a break
—even a few minutes without blood supply causes severe brain damage or death.
Virtually all other cells in the human body are stationary, but blood is mobile tissue, carrying nutrients to every part of the body—parts we see and parts most of us don’t even know exist—protecting us from harm, healing our wounds, and eliminating toxins that threaten to harm us.
