Structure of the kidney Flashcards
Kidneys contain something that carries out the processes of urine formation, what is this something?
nephrons
what role to ducts play in relevance to nephrons and the renal pelvis
ducts collect urine from the nephrons and convey it to the renal pelvis
what 3 things does a nephron consist of
glomerulus, glomerular, renal tubule
what is the glomerulus
small pin head sized tuft of aerterioles
a glomerular capsule does what
holds the glomerulus and allows fluid to pass from the blood into the collecting tubules
what is the glomerulus and glomerular capsule collectively called
renal corpsucle
What is the renal tubule
tiny collecting tube divided into 3 specialised regions
name the 3 regions of the renal tubule
proximal convoluted tubule, loop of henle and distal convoluted tubule
The endothelium of the arterioles in the renal corpuscle has small holes called what
fenestraions
what do fenestrations allow
fluid and solutes but not cells to leak out of the bloodstream
Endothelium of arterioles has what
Fenestrations
Finest rations allow for what
Fluid and solutes but not cells to leak out of blood
Large solutes such as plasma proteins are prevented from being filtered out the blood by
Basement membrane
Fluid emerging from basement membrane are further filtered by what
2nd layer of epithelial known as podocytes
Podocytes have projections called
Pedicels
