some substances are not normal components of urine because they are completely reabsorbed. choose all the substances that satisfy this requirement under healthy
conditions.

filtered plasma proteins
glucose
hydrogen ions
lactate
calcium ions
amino acids

Explanation:

Under healthy conditions, glucose and amino acids are completely reabsorbed in the proximal convoluted tubule of the nephron. Filtered plasma proteins are not filtered in significant amounts (due to their large size) and if any small - sized proteins are filtered, they are reabsorbed. Lactate is reabsorbed but not completely under normal conditions. Hydrogen ions are secreted (not reabsorbed in the sense of being removed from the filtrate to prevent their presence in urine in large amounts as they are involved in acid - base balance). Calcium ions are reabsorbed but not completely (some are excreted in urine).

Answer:

filtered plasma proteins, glucose, amino acids
