System Physiology NAME: LAB TIME/DATE: Simulating Glomerular Filtration The following questions refer to Activity 1: Investigating the Effect of Flow Tube Radius on Glomerular Filtration. 1. Describe the effect of increasing the afferent radius on glomerular filtration rate and glomerular pressure. As the afferent radius increases the glomerular filtration rate and glomerular pressure both increase the pressure in slow steps the filtration rate greatly increases. 2. Describe the effect

Glomerular Filtration Activity 1: Effect of Arteriole Diameter on Glomerular Filtration 1. Compare this data with your baseline data. How did increasing the afferent arteriole radius affect glomerular filtration rate? >>Increasing the afferent arteriole radius pushed the glomerular pressure‚ the glomerular filtration rate‚ and the volume of urine to be higher than the baseline data. Increasing the afferent arteriole radius increased the glomerular filtration rate. 2. Under

affect the rate of glomerular filtration (select all that apply)? Your answer : b. A decreased afferent arteriole radius will increase the rate of glomerular filtration. Correct answer: c. An increased afferent arteriole radius will increase the rate of glomerular filtration. d. A decreased afferent arteriole radius will decrease the rate of glomerular filtration. 2. If all other variables are kept constant‚ how does the efferent arteriole radius affect the rate of glomerular filtration (select all that

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

FORMATION 1. Glomerular Filtration 2. Tubular Reabsorption 3. Tubular Secretion 4. Excretion GLOMERULAR FILTRATION ž This is the movement of fluid and solutes out of the glomerulus‚ across the glomerular capillary membrane‚ and into Bowman’s capsule. ž The filtrate that is formed here should NOT contain any red blood cells or protein. ž Filtrate contains mostly water‚ NaCl‚ K+‚ bicarbonate‚ glucose‚ amino acids‚ creatinine and urea GLOMERULAR FILTRATION

Chapter 17 - Urinary System 17.1 Introduction (Fig. 17.1) A. The urinary system consists of two kidneys that filter the blood‚ two ureters‚ a urinary bladder‚ and a urethra to convey waste substances to the outside. 17.2 Kidneys (Fig. 17.2) A. The kidney is a reddish brown‚ bean-shaped organ 12 centimeters long; it is enclosed in a tough‚ fibrous capsule. B. Location of the Kidneys 1. The kidneys are positioned retroperitoneally on either side of the vertebral column between the twelfth
