Detailed explanation-1: -Selective reabsorption takes place in the proximal convoluted tubule (PCT) of the kidney. It is the process by which certain substances that are required by the body (such as glucose, amino acids, vitamins and water) but have been filtered out of the blood during ultrafiltration, are reabsorbed.

Detailed explanation-2: -Selective reabsorbtion occurs in the PCT (proximal convoluted tubule). The PCT is highly permeable meaning it is easy for molecules to diffuse through it.

Detailed explanation-3: -Final answer: Selective reabsorption of Glomerular filtrate takes place in Proximal Convoluted Tubules and Distal Convoluted Tubules.

Detailed explanation-4: -The proximal convoluted tubule is responsible for the most amount reabsorption of almost all filtered substances (sodium, glucose, amino acids, etc) and reabsorbs around 67% of each filtered substance.

Detailed explanation-5: -Selective reabsorption occurs because during ultrafiltration, important components of the blood are filtered out and they need to be reabsorbed into the body.
