The cup-like part located in the Malpighian body is called Bowman’s capsule. Its wall diameter is 0.2 mm. It is covered by squamous epithelium cells. Visceral and parietal layers. The outer layer is called parietal and the inner layer is visceral. The parietal layer is composed of epithelial cells. The visceral layer is composed of podocyte cells with flagella. Podocyte cells have finger-like pedicels at their free ends. Due to the position of the pedicels numerous pores are formed in the visceral layer. These holes are called filtration pore. Glomerular filtrate enters Bowman’s capsule through these pores. The space between the parietal and visceral layers is called capsular space. It is named Bowman’s capsule after Sir William Bowman.
