Which among the following substances are reabsorbed in the nephron?
Urea, Uric acid, Amino acid
Glucose, Amino acids, Salts
Glucose, Urea, Creatinine
KCl, Urea, Glucose
Glucose, Amino acids, Salts
Glucose, amino acids, salts and high amount of water are reabsorbed in the nephron during the second step of urine formation, i.e., the selective reabsorption. These essential substances were filtered out from the blood in the first step called glomerular filtration and are reabsorbed as they are vital for the functioning of our body.
