EXPLANATION
|
RENAL ARTERY
|
Carries Oxygenated Blood to the Kidney
|
KIDNEY
|
Two Bean - Shaped Organs that Filters the Blood
|
URETER
|
Tube Leading from the Kidney to the Bladder
|
BLADDER
|
Organ that Stores Urine (Excess Water, Salts and Urea) as it is Produced by the Kidney
|
URETHRA
|
Tube that Connects the Bladder to the Exterior; Where Urine is Released
|
RENAL VEIN
|
Carried Deoxygenated Blood Away from the Kidney

PROCESS:
Renal Artery will Transport Oxygenated Blood to the Bowman’s Capsule under High Pressure
Blood Enters the Glomerulus and is Filtered to Produce Glomerular Filtrate: Glucose, Water, Salts and Urea
The Glomerular Filtrate will Enter the Bowman Capsule and into the Tubules
All Glucose is Immediately Reabsorbed at the Proximal Convoluted Tubule by Active Transport, Rest of the Filtrate will Continue through the Tubules
Salts will Be Filtered by the Loop of Henle Depending on the Water Concentrations in the Body, the Remaining Filtrates will Continue through the Tubules
Water is Reabsorbed into the Blood at the Collecting Duct Depending on the Levels of ADH Produced (Water Levels in the Body)
The Collecting Duct will Collect the Excess Filtrates: Water, Salts and Urea and this will be Urine
This is Transported through the Ureter to be Stored in the Gall Bladder and is Removed from the Body through the Urethra
Renal Vein will Carry Deoxygenated Blood Away from the Kidney
