If the walls of the capillary cluster in a nephron were damaged or broken, what substance might you expect to find in urine that is not normally present? explain.

Broken capillaries occurs when the capillary walls narrow and widen too quickly causing the muscles in the walls tear. This in turn allows the blood to seep out resulting in broken capillaries.  I believe if the walls of the capillary cluster in a Nephron were damaged or broken Protein could pass into the nephron and end up in the urine. Blood cells might also be found in the urine.
