Nephrons are structural and functional units of kidneys. They are long, colied tubular structures. Each nephron shows the following parts - Malpighian body, proximal convoluted tubule, loop of Henle, distal convoluted tubule and collecting duct. The Malpighian body shows a cup-shaped Bowman's capsule, in which is present a tuft of capillaries called glomerulus.
Nephrons are the basic filtration units in kidneys. They filter the blood and form and concentrate urine. Useful substances are reabsorbed by the nephrons and put back into circulation.

Hydrogen resembles both alkali metals and halogens. It can lose one electron like alkali metals and also gain one electron like halogens. Like halogens, it forms diatomic molecule and combines with metals and non-metals to form covalent compounds. Therefore, position assigned to hydrogen in the periodic table is considered anomalous.

Resistivity is defined as the resistance offered by a unit length of conductor having unit area of cross-section .
Its S.I. unit is ohm-meter.
It does not change with the increase in length of wire but resistance becomes 4 times on stretching the wire to twice its length.
