Nephron
= the functioning unit of the kidney, the part that does the filtration and the
controlling of the composition of blood
The
image below shows the structure of the kidney and the position of the nephrons,
NB: There are millions of nephrons in each kidney for simplicity, only
one has been drawn in the diagram
The
image below outlines all the relevant sections of the nephron, and just below
that I have briefly explained what they are/do.
Glomerulus
– The knot
of blood vessels where the blood is filtered from
Bowman’s
Capsule – the
“Dead End” to the Nephron, Ultrafiltraion happens here [see 2.71]
Proximal
Convoluted tubule – The first twisted section
Loop
of Henlé
- The Nephron dips into the Medulla
Distal
Convoluted tubule – The second twisted section, back in the Cortex
Collecting
duct – The
final tube where the urine travels to the Pelvic region.
