Histology of the Renal and Urinary Systems Practical Session Objectives

What is the sequence of flow of glomerular filtrate through the renal tubules before it is excreted as urine?

What is the equation for urinary excretion?

What plays a more important role in determining the final urinary excretion rate for many substances: reabsorption or secretion?

What are some common disease processes that can be better understood by studying tubular functions?

What are some substances that are significantly secreted in the tubules?

Name a class of diuretics used in managing fluid overload.

What is the mechanism by which water and solutes are transported through the cell membranes in tubular reabsorption?

What type of transport is directly coupled to an energy source and moves solutes against an electrochemical gradient?

What are the two types of sodium glucose transporters present on the brush border of the proximal convoluted tubule?

What type of transport is indirectly coupled to an energy source and involves the interaction of two or more solutes with a specific membrane protein?

What is the mechanism by which some solutes are secreted into the tubules, often involving counter transport of the solute with the Na+ ions?

What type of transport reabsorbs large molecules via a type of endocytosis in the proximal convoluted tubule?

In tubular reabsorption, which type of transport is always passive?

What is the term for the maximum rate at which a solute can be transported due to saturation of the specific transport system?

What are the substances actively reabsorbed or secreted in the proximal tubule?

What is the term for the type of endocytosis utilized by the proximal convoluted tubule to reabsorb large molecules such as proteins?

What are the components of the urinary system?

Identify the major components of a nephron.

What is the function of the renal cortex?

What is the inner portion of the kidney called?

What is the functional unit of the kidney?

What are the two main components of a nephron?

What is the structure that surrounds the glomerulus?

What specialized layer of epithelial cells invests the capillary loops of the glomerulus?

What is the term for the small foot-like processes of the podocytes' cytoplasm?

What forms the glomerular filtration barrier?

What is the first segment of a renal tubule called?

What are the three segments of the loop of Henle?

What is the lining epithelium of the proximal convoluted tubule characterized by?

What is the permeability of the thin descending segment of the loop of Henle to water and solutes?

What is the last part of a renal tubule where distal tubules of several nephrons join to form a single tubule?

What type of cells fill the spaces between the capillary loops in the glomerular lobule?
