|
Answer» Filtration A\xa0nephron\xa0is the basic structural and\xa0functional\xa0unit of the kidneys that regulates water and soluble substances in the blood by filtering the blood, reabsorbing what is needed, and excreting the rest as urine. Its\xa0function\xa0is vital for homeostasis of blood volume, blood pressure, and plasma osmolarity.\xa0The nephron uses four mechanisms to convert blood into urine:\xa0filtration,\xa0reabsorption,\xa0secretion, and\xa0excretion. These apply to numerous substances. |
