General
=========================================================================

Metanephric blastema: forms glomerulus, proximal convoluted tubules, loops of Henle, distal convoluted tubules and connective tissue of renal interstitium
Ureteric bud: forms cortical and medullary collecting tubules and medullary collecting ducts

Stages of kidney development:
● Pronephros (based on Wolffian duct, kidneys non-functional)
● Mesonephros (appear at week 4, form nephron-like tubules but degenerate)
● Metanephros (form at week 5, function by week 11)
