Arteries are blood vessels responsible for carrying oxygen-rich blood away from the heart to the body. Veins are blood vessels that carry blood low in oxygen from the body back to the heart for reoxygenation. Arteries and veins are two of the body’s main type of blood vessels. These vessels are channels that distribute blood to the body. They’re part of two closed systems of tubes that begin and end at the heart. These systems of tubes are either: Pulmonary. The pulmonary vessels are arteries that transport oxygen-poor blood from the heart’s right ventricle to the lungs. Pulmonary veins transport oxygen-rich blood back to the heart’s left atrium. Systemic. The systemic vessels are arteries that carry oxygen-rich blood from the heart’s left ventricle to the tissues in all parts of the body. They then return oxygen-poor blood through the veins back to the heart’s right atrium.

Various factors such as common race, language, religion, aims and aspirations, culture and Shared past gave rise to nationalism.
The following factors were responsible for the rise of nationalism in Europe :
(i) Decline of Feudalism. There was a steady decline of federal lords and many of them died in mutual warfare. The crusades also improverished the barons. Federal lords were the major obstacle in the emergence of nationalism, and without their destruction the cause of nationalism might have greatly suffered.
(ii) Weakening Authority of the Pope. The Church enjoyed supreme and exalted position and commanded a great power in the middle Ages, but the Reformation movement as well as the Renvai-ssance led to awakening among the people and weakened the authority of the Pope. As a result, national churches and national states were established in many countries.
(iii) Wars. Wars roused nationalism among the people of both France and England. The Hundred Years’ War between in the two countries gave rise to national feeling both in France and England.
(iv) Foreign Rule. The foreign rulers suppressed the people and treated them cruelly and mercilessly. This led and united the people against the foreign rule and infused the spirit of nationalism in them.
