Final answer:
The filtrate entering the DCT is different from the filtrate in the glomerular capsule as it undergoes reabsorption and modification before entering the DCT.
Step-by-step explanation:
The filtrate entering the Distal Convoluted Tubule (DCT) is different from the filtrate in the Glomerular capsule. In the Glomerular capsule, filtration occurs under high pressure, resulting in the formation of a filtrate that mainly lacks cells and large proteins.
On the other hand, in the DCT, approximately 80% of the filtered water has already been reabsorbed, and the DCT further reabsorbs another 10-15% before the forming urine enters the collecting ducts. Additionally, the DCT can also secrete substances into the urine.
Therefore, while the filtrate in the glomerular capsule is the initial result of filtration, the filtrate entering the DCT has already undergone significant reabsorption and modification.
