  • (20) These studies demonstrate that net oxalate secretion occurs in the early portions of the proximal convoluted tubule, undergoes bidirectional transport of approximately equal magnitude in later segments of the proximal tubule, and probably is not transported in more distal nephron sites.

Tortuous


Definition:

  • (a.) Bent in different directions; wreathed; twisted; winding; as, a tortuous train; a tortuous train; a tortuous leaf or corolla.
  • (a.) Fig.: Deviating from rectitude; indirect; erroneous; deceitful.
