Draw a small round Bowman’s capsule
Draw a tuft of capillaries inside it for the glomerulus
Extend a short tube from the capsule for the proximal convoluted tubule
Draw the proximal tubule as a coiled segment
Continue the tube downward to form the loop of Henle
Draw the loop as a U-shaped bend
Extend the tube upward after the loop
Draw another coiled segment for the distal convoluted tubule
Connect the distal tubule to a collecting duct
Draw the collecting duct as a straight vertical tube
Add nearby blood vessels around the nephron
Label the glomerulus, Bowman’s capsule, proximal tubule, loop of Henle, distal tubule, and collecting duct
