Question

Quizplus · Accepted Answer

Filtrate reabsorption that occurs regardless of the concentration and volume of urine produced is referred to as obligatory reabsorption. This is because certain substances, such as glucose and amino acids, are always reabsorbed in a fixed amount by the body, regardless of the body's needs at the time. Obligatory reabsorption mainly occurs in the proximal convoluted tubule.
