The epithelial tissue that lines the kidney tubules is known as simple cuboidal epithelium. This particular type of epithelium consists of a single layer of cube-shaped cells.
Simple cuboidal epithelium plays a crucial role in the kidneys, particularly in the renal tubules where it is involved in functions such as secretion and absorption. The cube-like structure of these cells allows for efficient transportation of substances, making them well-suited for their function in the nephron, the functional unit of the kidney.
Additionally, the cells have microvilli on their apical surface, which increases the surface area for absorption. This structural adaptation helps the kidneys effectively process filtrate and maintain homeostasis in the body.
