Introduction: In this lab we will learn how the kidney processes blood and produces urine.
Activity 1: Investigating the Effect of Flow Tube Radius on Glomerular filtration.
Data/Results: Questions: Please answer the questions in complete sentences and explain your answers.
1. What effect does increasing the afferent radius have on glomerular filtration rate and pressure? Both the rate and the pressure increase as you increase the afferent radius.
2. What effect will decreasing the efferent radius have on glomerular filtration rate? When I decreased the efferent radius, it increased the filtration rate. Please see table below:
Summary:
In this Activity, I learned/observed that: the nephron has three important jobs on filtering the blood. Glomerular Filtration speed can be affected by the efferent radius and by the afferent radius. Which makes since, because it is like saying the size of the pathway for the blood will make a difference on how fast it is filtered.
Activity 2: Studying the Effect of Pressure on Glomerular Filtration
Data/Results: Please submit a chart or type your data.
Questions: Please answer the questions in complete sentences and explain your answers.
1. What effect does increasing the beak pressure have on glomerular filtration rate and pressure? When you increase the beak pressure, the glomerular filtration rate and the pressure are both increased.
2. In the absence of any regulatory mechanisms, what effect do you think an increase in blood pressure would have on glomerular filtration rate? If there is an increase in blood pressure, I would assume there would be an increase in the glomerular filtration rate, therefore causing an increase in the amount of urine.
