Will this be a problem regarding urine formation? The mechanisms involve various hormones and electrolytes and are largely dependent on the amount of metabolic activity, the extrinsic control mechanism depending on the perfusion needs of the cells, and the vascular resistance generated by the blood pressure.
Increasing the afferent arteriole radius increased the glomerular filtration rate. Compare this data with your baseline data. The less water reabsorbed, the more urine will be formed.
In contrast, when the amount of fluid to be filtered is less, the urine will become concentrated. Activity 5. How does this compare to the effect of adding aldosterone, with respect to potassium concentration in the urine?
As pressure increased, what happened to the pressure in the glomerulus? How did increasing the afferent arteriole radius affect glomerular filtration rate?
The constriction of the efferent radius will limit blood drainage out of the glomeruli and that requires increasing the glomerular filtration rate.Aldosterone caused just slight decrease in the urine volume. The glomerular filtration rate decreases and that will definitely decrease the urine formation but as long as the remaining nephrons are functional urine formation will not be a problem. If blood pressure went down — for example, as the result of blood loss — what changes would the kidney need to make to maintain its normal filtration rate? How did increasing the efferent radius affect glomerular filtration rate? How does the addition of ADH affect the concentration of potassium in the urine? Review Sheet Exercise 8 wowkeyword. That means aldosterone has the capability to spare some potassium for reabsorption while ADH cares less about keeping it. Physioex 8. Compare this data with your baseline data. The other physiological functions particularly the metabolic functions of the body also decline with age and that can significantly decrease the workload of the nephrons.
