Draw the kidney slide in color. Kidney histology at high power. Notice the glomerulus and the proximal and distal tubules. The proximal is active in reclaiming nutrients. Therefore there is more mitochondria and the cells have microvilli to increase surface area. The PCT have taller, pinker epithelium. The lumen is more cloudy due to the microvilli. Draw the following slide in color. Indicate the glomerulus, Bowman's capsule, proximal and distal convoluted.
