Filtrates in the Bowman's capsule contain vitamins because
they have low molecular weight.
most of them are fat soluble.
they cannot be reabsorbed into the blood.
little amount is required by the blood.
توضیح
Filtrates in the Bowman's capsule contain vitamins because the filtration process in the kidney allows small molecules like vitamins to pass through from the blood into the Bowman's capsule, while larger molecules like proteins are retained in the bloodstream; essentially, the filtrate is composed of blood plasma minus the large proteins, which means it includes most of the small molecules present in the blood, including vitamins.
