For drawing any figure of biology, you need to first of all understand its theory. In case of the nephron figure, the parts of the nephron and their functions should be known before you attempt to draw the figure. Once you are thorough with the theory aspect, you will begin to find the figure easy to draw. Also remember that constant practice is needed to gain mastery over the figure. In case of nephron, draw the Bowman's capsule and glomerulus first followed by the tubular part and collecting duct. Then you can add on the renal artery and branch of renal vein.
You could take any one of the figure given in the following sites. The labels are not exactly the same, since the parts of the nephron are also labelled. The labeling of proximal convoluted tubule, loop of Henle and distal convoluted tubule need not be given, instead you need to name any region after the glomerulus as the tubular part of nephron. Branch of renal vein is not shown in these figures. These are some of the simplest figures available, as also is the NCERT figure.
