The Battle of Verdun in 1916 was the longest single battle of World War One. The casualties from Verdun and the impact the battle had on the French Army was a primary reason for the British starting the Battle of the Somme in July 1916 in an effort to take German pressure off of the French at Verdun. The Battle of Verdun started on February 21st 1916 and ended on December 16th in 1916. It was to make General Philippe PÃ©tain a hero in France. The attack on Verdun (the Germans code-named it âJudgmentâ) came about because of a plan by the German Chief of General Staff, von Falkenhayn.

Heartâs Chambers and Valves. The heart has four chambers. The two ventricles (right and left) are muscular chambers that propel the blood out of the heart. The right ventricle pumps blood to the lungs, and the left ventricle pumps blood to all other organs. The two atria (right and left) hold the blood returning to the heart, and at just the right moment empty into the right and left ventricles.
