Difference between PCT and DCT |
||
| Answer» | PROXIMAL CONVOLUTED TUBULE | DISTAL CONVOLUTED TUBULE | \t\t\tThe cells present in the Proximal Convoluted Tubule (PCT) have brush border which is capable of absorption.Distal Convoluted Tubule (DCT) is the highly coiled part found in the medulla of the kidney.URINEProximal Convoluted Tubule (PCT) receives primary urine from glomerulus.Distal Convoluted Tubule (DCT) receives urine from the glomerulus.RESULTS INPCT regulates excretion of urine by absorbing excess water from primary urine.In DCT, water and salts are secreted.FUNCTIONA small amount of tubular secretion also takes place in the Proximal Convoluted Tubule (PCT).The secretion of wastes of ions takes place in the Distal Convoluted Tubule (DCT).OTHERSThe substances which are reabsorbed into peritubular network from PCT are glucose, amino acid\'s, vitamin-c, potassium, Calcium, sodium chloride, 75% of water, etc.The substances like urea, uric acid, creatinine, sodium, potassium, hydrogen ions are secreted into DCT.\t|
