If you connected all of the veins, arteries and capillaries in one human, it would form a line 60,000 miles long, wrapping around the earth’s equator 2.5 times. Capillaries, which are the smallest vessels, have a diameter that’s 1/10th the diameter of the human hair (or 1/3000th of an inch). Because red blood cells are approximately this same size, they must travel through these capillaries single file.
Scientists are mimicking vascular structures in new materials that are designed to assist with wound healing and skin grafts. This field of science is called ”microfluidics”.
Scientists that are copying God's creation don't realize if they have to copy the more intelligent design, it could not have come about by randomness or trial and error. God truly did it better, and we are wonderfully made!
Psalm 139:14 I praise you because I am fearfully and wonderfully made
