The medical term for dilation of a calyx is caliectasis. It refers to the enlargement or dilation of the calyces, which are part of the kidney's collecting system that helps transport urine to the renal pelvis.
No, calyx and sepal are not the same thing. The calyx is the collective term for all the sepals of a flower, while a sepal is one of the leaf-like structures that make up the outermost part of the flower. Sepals can be separate or fused together to form the calyx.

Bracteole and calyx
the papilla duct of each renal pyramid is in cup called a minor calyx which collects urine. The 2 or 3 minor calyx converge to make a major calyx.
Calyx is usually green, and smaller than Corolla; Corolla is coloured, delicate textured than Calyx

unire fromed in the kidney passes through a renal papilla at the apex into a minor calyx
Urine is in the major calyx but I don't know what else, sorry.
the four whorls of a flower are : 1.calyx 2.corolla 3.androecium 4.gynoecium
Calyx (plural: calyces) means "cup" or seed pod/outer covering (from it botanical usage). In anatomy it refers primarily to that tissue which surrounds the apex of the renal pyramid. Urine passes through the papilla (apex) into the calyx and finds it was outside in the renal pelvis and dribbling down the ureter to be held in the urinary bladder until urination.
Bougainvilleas do not have calyx or corolla. Only petaloid perianth lobes are found.
