Draw a long, thin line for the renal tubule
Add a round Bowman’s capsule at one end
Draw a small ball of capillaries inside the capsule for the glomerulus
Extend the tubule from the capsule to form the proximal convoluted tubule
Draw a U-shaped loop for the loop of Henle
Continue the tubule upward to form the distal convoluted tubule
Draw the tubule leading into a collecting duct
Add nearby blood vessels if needed
Label the glomerulus, Bowman’s capsule, proximal convoluted tubule, loop of Henle, distal convoluted tubule, and collecting duct
