Breathing is the process of moving air into and out of the lungs. The process depends on a muscle called the diaphragm. This is a large, sheet-like muscle below the lungs. Inhaling, or breathing in, occurs when the diaphragm muscle tightens. This increases the size of the chest. This too decreases air pressure inside the lungs. This action allows air and gases to enter the lungs. Exhaling, or breathing out, occurs when the diaphragm muscle relaxes. This decreases the size of the chest. This increases air pressure inside the lungs. This action allows for air to leave the lungs. When you inhale, air enters the respiratory system through your nose and ends up in your lungs, where gas exchange with the blood takes place. What happens to the air along the way? In the nose, mucus and hairs trap any dust or other particles in the air. The air is also warmed and moistened. Next, air passes through a passageway that is connected to the windpipe. The air then finds its way to the lungs. In the chest, the windpipe splits so that air enters both the right and left lung.

The French have always wanted to know what it means to be aFrenchman. Their history has been a constant quest for national identity: a conflict between strong regional loyalties and central authority. In about 2000b.c. Celtic tribes probably from eastern Europe came looking for greener pastures in the areas that are now Franche-Comte, Alsace, and Burgundy. At the same time, migrants from the Mediterranean countries were trickling into the south. The first recorded settlement was the trading post set up by Phocaean Greeks from Asia Minor at Massalia (Marseilles) around 600b.c. , followed by other ports at Hyeres, Antibes, and Nice. But the Greeks developed few contacts with the interior beyond a little commerce in olives and wine with the Celts of Burgundy. When their position was threatened by Ligurian pirates at sea and warlike tribes from inland, the merchants of Marseilles called on Rome for help. From Gaul to France In 125b.c. , the Romans came in force, conquered the "Gallic barbarians," and set up a fortress at Aquae Sextiae (Aix-en-Provence). They took advantage of this new stronghold to create Provincia (now Provence), stretching from the Alps to the Pyrenees, in order to guarantee communications between Italy and Spain. When this province was endangered by fresh attacks from the north, Julius Caesar himself took charge, conquering practically the whole of Gaul by 50b.c. Caesar drew Gaul's northeastern frontier at the Rhine, taking in present-day Belgium, and warned that the Germanic tribes across the river the Franks (after whom France is named), Alamans, and Saxons would always threaten the security of the frontier. The Romanization of Gaul sent the most energetic warriors to defend the outposts of the empire while their families settled down to work the land or build towns such as Lyon, Orange, Arles, and Nimes, and the first great highways between them. At the same time, merchants built up a thriving trade with the rest of the Roman Empire. The pattern for the peasantry and bourgeoisie of France was thus established. Christianity was introduced into Gaul in the first century a.d.

The explosion, while killing one of the Cossacks and seriously wounding the driver and people on the sidewalk, had only damaged the bulletproof carriage, a gift from Napoleon III of France. The emperor emerged shaken but unhurt. Rysakov was captured almost immediately. Police Chief Dvorzhitsky heard Rysakov shout out to someone else in the gathering crowd. The surrounding guards and the Cossacks urged the emperor to leave the area at once rather than being shown the site of the explosion. Nevertheless, a second young member of the Narodnaya Volya, Ignacy Hryniewiecki, standing by the canal fence, raised both arms and threw something at the emperor's feet. He was alleged to have shouted, "It is too early to thank God". Dvorzhitsky was later to write:
