Normal and altered urine Flashcards
What is a glomerulus?
TUFT of capillaries
What is the glomerulus sandwiched between?
Afferent and efferent arterioles
Explain how the afferent and efferent arterioles work
Pressurised blood through the muscular afferent arteriole to the glomerulus.
Forced to exit through a narrow tubule of the efferent arteriole.
Where does ultrafiltration occur ?
Glomerulous
Where do secretion and reabsorption occur in the nephron ?
Proimal convuluted tubule
Where does formation of an osmolarity gradient occur within the nephron ?
Loop of henle
Where does final reabsorption of water occur within the nephron?
Collecting Duct
What cells does the glomerulous have ?
Fesnerstated cells
When does glomerular filtration occur ?
Glomerular filtration occurs when glomerular (blood) hydrostatic pressure exceeds the hydrostatic pressure of the glomerular capsule and the blood colloid osmotic pressure.The sum of all of the influences, both osmotic and hydrostatic, results in a net filtration pressure (NFP).
