Functions of the Urinary/Renal system
|
removal of metabolic waste Nitrogenous and foreign bodys from plasma.
Regulate plasma ionic composition regulate plasma valume regulate plasma osmolarity regulate ph secrete erythropoietin. |
|
|
Anatomy of Urinary System
|
Kidneys
ureters bladder urethra |
|
|
Anatomy of kidney
|
cortex
medulla pelvis nephron renal corpuscle renal tube |
|
|
nephron:
|
funcrional unit of the kidney
made of renal corpuscle & renal tubual |
|
|
anatony of
renal corpuscle: |
Glomerular or ( bowmans's)capsule
& Glomerulus |
|
|
anatomy of
renal tubule : |
(PCT)- proxamal convoluted tubule
(DCT)- distal convoluted tubule Loop of Henle & collecting duct |
|
|
DCT- distal convoluted tubual
starts flow to: |
collecting duct ->
papillarty duct -> minor calyx -> major calyx -> to the pelvis of kidney |
|
|
Blood Supply
flow in the kidney flows: |
Renal -> segmental -> interLOBAR -> arcurte ->
interLOBULAR -> Afferent art-> glomerulus -> Efferent art -> peritubular capillaries -> interLOBULAR vein |
|
|
Juxtaglomerular apparatus(JGA)
JG Cells : |
JG cells are granular and contain renin - JGA are in the arteriole and respond to
mechanoreceptors detecting arteriole strech from changing blood pressure |
|
|
Distal convoluted renal tubual (DCT)
Macula densa cells : |
chemorecepters (osmoreceptors)
that respond the the changing flow rate and solute content of the filtration |
