What is the shape of renal epithelial cells when observed under a microscope?

• A. Slightly larger than WBCs and more uniform
• B. Large and irregular
• C. Spherical with unequal nuclei
• D. Flat and spread out

Answer: (A)

The shape of renal epithelial cells, when observed under a microscope, is primarily characterized by their slightly larger size compared to white blood cells and their more uniform appearance. Renal epithelial cells, which line the tubules of the kidneys, typically exhibit a cuboidal or columnar shape. This structure allows them to perform functions such as absorption and secretion effectively.

The uniformity in size and shape is important for maintaining optimal function within the renal system. These cells also contain a prominent nucleus, which can sometimes make them appear larger than white blood cells, but they maintain a consistent morphology across the renal tubules.

Understanding the morphology of these cells is crucial for identifying various pathological conditions that may affect kidney function, where abnormal sizes, shapes, or arrangements may indicate disease.
