Consider the following statements regarding the microscopic structure of the human nephron: 1. Podocytes are specialized epithelial cells present in the inner wall of Bowman's capsule, leaving minute spaces called filtration slits. 2. The Henle's loop is highly developed in desert mammals to facilitate the conservation of water by producing concentrated urine. 3. The proximal convoluted tubule (PCT) is lined by simple squamous epithelium which increases the surface area for maximum reabsorption. Which of the statements given above is/are correct?
