This structure is responsible for the selective filtration of the blood in the glomerulus. It is made up of three layers.
Glomerular Filtration Rate
The volume of fluid filtered from the capillaries into the bowmans capsule every minute.

Medullary Ray
Middle part of a renal lobule. Its a straight tube which a nephron drains into and it connects to a collecting duct. They are only in the renal cortex and its name refers to where it is heading not where it is located.
Micturition
Is the normal process of the passive storage and active voiding of urine

N

Natriuresis
Abnormal amounts of sodium loss in the urine
Nephron
The functional unit of the kidney consisting of the renal corpuscule and renal tubule.

O

P

Pressure Diuresis
Increasing blood pressure increases urinary output
Pressure Natriuresis
When blood pressure is increased sodium reabsorption decreases. This helps to restore blood pressure back to normal

R

Renal Clearance
Is dependant on glomerular filtration rate and demonstrates the kidneys ability to remove a compound from the blood.
Renal Corpuscule
Consists of the glomerulus and Bowman's capsule, a single layer of epithelial cells (podocytes) resting on a basement membrane.
Renal Lobe
The kidney has several lobes each consists of a renal pyramid and the piece of cortex above it
