2.70 - Nephron Structure

Branch of Aorta taking blood into the kidney is called the Renal Artery 

Kidney filters the blood

Contents which are removed are called Urine (through Ureter) - collects in Bladder

Filtered blood goes through the Renal Vein 

Out region - Cortex

Inner region - Medulla

The Space - Pelvic region - where the urine collects and drains down the ureter

Different colour because the kidney is made up of millions of tubes

Tube starts on the edge of the medulla and goes out into the cortex, then winds and then drops down to the medulla again, then winds and comes to a dead end. 

The dead end is called the Bowman's capsule. 

The tube structure is called a Nephron

Above the dotted line - Cortex 

Below the dotted line - Medulla

Twisted sections - Convoluted tubules 

The dip - loop of Henlé 

Dead end cup shape structure - Bowman's Capsule 

Tight knot of blood vessels - Glomeruloui

First twisted section - Proximal convoluted tubules (PCT) 

Second twisted section - Distal convoluted tubules (DCT)

This nephron structure is what gives the different colours - millions of them
