The ultimate nutrition supplier to the body cells - Capillaries!

Small is not only beautiful but also essential to life! We take food to supply nutrition to our body.  How and from where this nutrition is received by the tissue cells of our body? Do you know? We all know that our heart pumps blood from the body organs to the lungs, and then returns the purified blood back to the body organs. But there is also a microcirculation existing at a microlevel between arteries, arterioles and the venules, veins! The components of this circulation are the Capillaries. Only through the walls of these capillaries, the nutrition is received by the tissue cells!
