the process that initiates urine formation in most types of vertebrates is ultrafiltration of fluid from the blood plasma into kidney tubules under the force of blood pressure. What properties of the blood plasma in the urine-forming structures of the kidney are likely to affect the rate of ultrafiltration into the kidney tubules?
