What type of cells resemble cats and are described as convoluted?

The correct choice identifies the cells in the distal convoluted tubule (DCT) as those that are described as "convoluted" and resembling "cats." The term "convoluted" refers to the characteristic structure of the DCT, which is highly folded or twisted, allowing for increased surface area for the reabsorption of substances from the tubular fluid back into the blood.

Distal convoluted tubule cells are cuboidal in shape and lack the microvilli that are found in proximal convoluted tubule cells. Their functionality involves further adjustments in the filtrate, particularly in electrolyte balance and acid-base homeostasis. The distinct structure and arrangement of these cells contribute to their resemblance being compared to "cats," likely due to their agile nature and compact forms.

Other cell types mentioned do not fit this description as closely. Proximal convoluted tubule cells, while also convoluted, have a different shape and organization, primarily designed for significant reabsorption. Collecting duct cells play a role later in urine concentration and do not exhibit the convoluted appearance that characterizes the DCT. Renal epithelial cells is a broader term that encompasses various cell types found in the kidney and does not specifically refer to the convoluted structure associated
