Detailed explanation-1: -Ultrafiltration is the process of filtering small molecules from blood to the glomerular filtrate at the glomerular capsule . On the other hand, selective reabsorption is the process of absorbing important substances from the ultrafiltrate back to the blood at the proximal convoluted tubule.
Detailed explanation-2: -The nephrons work through a two-step process: the glomerulus filters your blood, and the tubule returns needed substances to your blood and removes wastes. Each nephron has a glomerulus to filter your blood and a tubule that returns needed substances to your blood and pulls out additional wastes.
Detailed explanation-3: -Selective reabsorption is the process whereby certain molecules (e.g. ions, glucose and amino acids), after being filtered out of the capillaries along with nitrogenous waste products (i.e. urea) and water in the glomerulus, are reabsorbed from the filtrate as they pass through the nephron.
Detailed explanation-4: -It takes place in the Proximal Convoluted Tubule, or PCT, Henle loop, Distal Convoluted Tubule, or DCT, and collecting duct.
