꧁ ꧁  💖ৡ  W ay Of Living   2 ৡ 💖 ༒ ꧂ * 🔆🔆🔆STORY 06.09.2020🔅🔅🔅  Anger is man's greatest enemy.  Just as fire is born of wood and burns that wood, anger stays in our body and destroys the body.   The greatest service is to share the joys of life with others.  As long as you blame others for your own problems and sorrows, know that your problems and sorrows will never go away.   God has given you a hand when you write so that your enemy will love you too.  In the same way the brain has given judgment, so that even the guilty will shed tears of remorse.  And God has given us the mind and the heart to think well, so that you may think that just as this earth dances on the good of every creature, so you can go and keep the dignity of the human word.                      🙏🙏END🙏🙏   ꧁ ꧁  💖ৡ  Jay Jagannath🙏🙏ৡ 💖 ༒ ꧂ *

Red blood cells are responsible for carrying oxygen from your lungs to your cells and for carrying carbon dioxide from your cells to your lungs where it is exhaled. White Blood Cells- White blood cells defend the body against attack from foreign organisms, such as bacteria and some viruses and form antibodies that protect the body from future attacks. If the body is invaded by harmful organisms, the production of white blood cells increases dramatically. When a white blood cell encounters a smaller organism, it simply engulfs it. If the invading organism is larger, a number of whi...
