The body’s river retains an age-old tie to Earth‘s waters. Like it’s prototype the ocean, blood is a crowded sea, teeming with a diverse society of cells that carry out specific tasks and coexist in strict proportions. So critical is this balance that a decline in the population of any one element can endanger life.
The red blood cells constitute about 45% of blood’s volume. EVERY red blood cell contains about 270,000,000 complex proteins to carry oxygen to our body parts. In turn, so many red cells crowd the bloodstream of a single human that stacked, these cells could reach 31,000 miles in the sky.
Amazing isn’t it?
