Explanation:
Detailed explanation-1: -Urea is not reabsorbed during urine formation.
Detailed explanation-2: -Glucose, amino acids, NaCl and other essential salts are reabsorbed in the second step of urine formation i.e Tubular Reabsorption. These essential substances are filtered from blood in the first step called glomerular filtration and are reabsorbed as they are vital for body function.
Detailed explanation-3: -The substances that are not filtered through the nephrons are plasma proteins and blood cells as their large size prevents them from crossing the fenestrations of the glomerular filtration membrane.
Detailed explanation-4: -Urea is not required by the body. So, it is not reabsorbed.
