Question

bio1130 exam 2 - chapters 19,17, and 20 (2 attempts) 40 the renal medulla contains __________, whereas the renal cortex contains __________. multiple choice renal pyramids; ureters from nephrons renal corpuscles; nephron loops renal columns; renal pyramids and nephrons renal pyramids; renal corpuscles

Explanation:

The renal medulla is the inner part of the kidney. It contains renal pyramids which are triangular - shaped structures. The renal cortex is the outer part of the kidney. It contains renal corpuscles which are the starting point of the nephron (the functional unit of the kidney).

• Renal pyramids are not in the cortex and ureters are not part of the nephron structure within the kidney parenchyma.
• Renal corpuscles are in the cortex, not the medulla, and nephron loops (Henle's loops) are mainly in the medulla.
• Renal columns are extensions of the cortex into the medulla, and renal pyramids are in the medulla, not the cortex.

Answer:

renal pyramids; renal corpuscles
