Proximal Convoluted Tubule
The kidney is the primary site of toxin filtering in the human body. This is mostly done by a filtering region in the kidney called the proximal convoluted tubule (PCT). As the blood passes through the vessel adjacent to the PCT cells water, proteins, polypeptides, and amino acids are reabsorbed.
