Accepted Answer

The nephrons are the urine-producing tubules of the kidney. The renal pelvis is the flat, funnel-shaped cavity that collects urine from the nephrons and drains it into the ureter. The renal medulla is the innermost part of the kidney, composed of tissues that are responsible for producing urine. The renal cortex is the outer layer of the kidney, consisting of tissues that filter the blood and produce urine.
