You are dissecting a kidney in class and, after cutting a sagittal section through the kidney, decide to remove some of the lighter-colored inner structures near the superior end of the ureter. you remove a funnel-shaped sac that connects directly into the ureter, along with many tubes that converge to form the funnel-shaped sac. which structures have you removed?

The renal pelvis and the calyces.

Explanation:

Kidney plays an important role in the excretion of the organisms. The kidney consists of millions of neurons that acts as the filtration unit and consists of coiled networks.

The renal pelvis is funnel like in shape that helps in the fluid elimination and helps in the direct connection with uterus. The three or more fibre structure condense at the renal pelvis to form the calyces. These structures helps in the transport of the filtered urine.

Thus, the correct answer is renal pelvis and the calyces.
