BIO 265 Section 7.2: Study Guide Section 7.2 Objectives: Describe the process of filtration, reabsorption, secretion, and excretion. Describe the process of how the kidneys nephrons regulated the Glomerular Filtration Rate. 7.2 –FILTRATION, REABSORPTION, AND SECRETION 7.2.1 – Filtration Describe the overall processes of filtration, reabsorption, secretion, and excretion.
Explain what the Glomerular Filtration Rate (GFR) is.
o What is the normal GFR range? o How does blood pressure change the GFR?
Describe how autoregulation of the afferent and efferent arterioles work to maintain the proper pressure in the Glomerulus. Draw your own diagram to show this process. o Test yourself: What would happen to pressure in the glomerulus if you
dilated the afferent arteriole and constricted the efferent arteriole?

BIO 265 Describe how Net Filtration Pressure (NFP) is calculated. What are the different forces or pressures influencing the NFP and what influences them?
