If by knot you mean a complicated intertwining of capillaries surrounding the nephron, they are called the peritubular capillaries. They are largely responsible for the bodies ability to concentrate urine and maintain homeostasis.
Renal capillaries, aka the glomerulus, where nitrogenous wastes and excess water in the blood plasma diffuse over to the nephron to be filtered and excreted.
This is a tuft of capillaries called the glomerulus. The glomerulus is one of the key structures that make up the nephron, the functional unit of the kidney.
