The reasons for the growth of the Nationalist tension in the Balkan region before the first World war are highlighted below:

● The Balkan was the region of geographical and ethnic variation comprising modern-day Romania, Albania, Bulgaria, Greece, Serbia, Croatia, etc.

● A large part of the Balkan was under the control of the Ottoman Empire.

● It was an explosive area due to the spread of the ideas of romantic Nationalism in Balkan and the disintegration of the Ottoman Empire.

● The Empire was not even able to strengthen itself through modernization and internal reforms.

● The people of the Balkan claimed for independence and political rights using their nationality and history to prove that they were an independent nation but were subjugated by a foreign power.

● The people struggled to define their identity and their Balkan area became an area of intense conflict.

● At the same time the great European powers of Russia, England, Germany and Austro Hungary were keen on capturing this area as it was important from the viewpoint of trade.

● This led to a series of War and finally became the cause of the first world war.

Nephron is the basic functional unit of kidneys that consists of a glomerulus and its associated tubules through which the glomerular filtrate passes before it emerges as urine.

Functions of Nephron

The primary function of nephron is removing all waste products including the solid wastes, and other excess water from the blood, converting blood into the urine, reabsorption, secretion, and excretion of numerous substances.

As the blood passes through the glomerulus with high pressure, the small molecules are moved into the glomerular capsules and travel through a winding series of tubules.

The cell present in each tube absorbs different molecules excluding the glucose, water, and other beneficial molecules which are called ass the ultrafiltrate.  As the ultrafiltrate molecules travel down the tubules they become more and more hypertonic, which results in more amount of water to be extracted from the ultrafiltrate before it exits the nephrons.

The blood surrounding the nephron travels back into the body through the renal blood vessels, which are free of toxins and other excess substances. The obtained ultrafiltrate is urine, which travels down via the collecting duct to the bladder, where it will be stored and released through the urethra.
