Did you know that the most amazing product transportation system ever devised is located inside your own body?
The fascinating properties of blood deliver oxygen and remove waste through arteries and veins, a flexible tube system that carries blood to and from our cells. Our blood is mostly made up of plasma that carries the other solid materials: red blood cells, white blood cells and platelets. Red blood cells carry oxygen, white blood cells fight infections, and platelets plug leaks in the veins and arteries.
The 75 trillion cells in your body have many common characteristics. Each cell must breathe; each cell needs oxygen and food as fuel; each cell gets hot and needs cooling; each cell performs work and gives off exhaust gas and waste products. God has combined all of the required functions into one system in our body – the circulatory system.
Blood carries food, oxygen and other required chemicals and minerals. It constantly moves required nutrients from processing sites to delivery points and transports waste from the cells to disposal plants. It even acts to surround and destroy invading enemies (like germs) and replace worn out or damaged parts of a cell. The motor of the circulatory system is the heart, a two cylinder pump, which keeps working even as we sleep, sit, or run a race.
The intricate circulatory system is evidence of the Creator’s workmanship!
