Verified step by step guidance

Understand the question: The problem is asking which structure is lined by simple cuboidal epithelium with tall microvilli, which is specialized for maximum reabsorption. This requires knowledge of epithelial tissue types and their functions in specific organs.

Review the characteristics of simple cuboidal epithelium: This type of epithelium consists of cube-shaped cells with a single layer. It is often found in areas where absorption and secretion occur. The presence of tall microvilli increases the surface area for reabsorption.

Analyze the options: Evaluate each structure based on its epithelial lining and function. For example, the esophagus is lined by stratified squamous epithelium for protection, not reabsorption. The alveoli of the lungs are lined by simple squamous epithelium for gas exchange, not reabsorption. The urinary bladder is lined by transitional epithelium to allow stretching, not reabsorption.

Focus on the proximal convoluted tubule: This structure, found in the nephron of the kidney, is lined by simple cuboidal epithelium with tall microvilli. Its primary function is to reabsorb water, ions, and nutrients from the filtrate back into the bloodstream, making it the correct answer.

Conclude: The proximal convoluted tubule is the only structure among the options that matches the description of being lined by simple cuboidal epithelium with tall microvilli for maximum reabsorption.
