Question 1
Bowman's Capsule
Is a capsule-shaped membranous structure surrounding the glomerulus of each nephron in the kidneys of mammals that extracts wastes, excess salts, and water from the blood
Glomerular Filtrate
Is a renal process whereby fluid in the blood is filtered across the capillaries of the glomerulus and into the urinary space of Bowman's capsule.
Question 3
Podocytes
Are cells in the Bowman's capsule in the kidneys that wrap around capillaries of the glomerulus.
Question 4
Pedicels
Is a secondary process of a podocyte, which helps form the visceral capsule of a renal corpuscle.
Question 5
Filtration Slits
Are intercellular clefts between the interdigitatingpedicels of podocytes; they are part of the filtration barrier of renal corpuscles.
Question 6
Slit Diaphragm
Is made of nephrin and various proteins that are synthesized by the podocytes, extends across the filtration slits.
Nephrin
Is a zipper-like protein that forms the slit diaphragm, with spaces between the teeth of the zipper, big enough to allow sugar and water through, but too small to allow proteins through.
Fenestrated Endothelium
That there are pores (fenestrae or fenestrations "windows") that penetrate through the endothelial cells.
Question 9
Glomerular-Capsular Membrane
Is a cup-like sac at the beginning of the tubular component of a nephron in the mammalian kidney that performs the first step in the filtration of blood to form urine
Question 10
Juxtaglomerular Apparatus
Is found next to the glomerulus. It is found between where blood enters a renal corpuscle and distal convoluted tubule of the same nephron.
Juxtaglomerular Apparatus (function)
This location is critical to its function in regulating renal blood flow and glomerular filtration rate.
Question 12
Macula densa
Is an area of closely packed specialized cells lining the wall of the cortical thick ascending limb of the loop of Henle. And to the distal convoluted tubule.
Question 13
Juxtaglomerular Cells
Are cells in the kidney that synthesize, store, and secrete the enzyme renin. They are specialized smooth muscle cells mainly in the walls of the afferent arterioles.
Extraglomerular Mesangial Cells
Are strategically positioned between the macula densa and the afferent arteriole. These cells form a syncytium.
Question 15
Syncytium
Is a multinucleate mass of cytoplasm resulting from fusion of cells
