The closed end at the start of the nephron- it is cup shaped and surrounds a mass of blood capillaries known as the glomerulus, inner layer of renal capsule is made up of specialised cells called podocytes

Proximal convoluted tubule
Series of loops surrounded by blood capillaries. its walls are made of epithelial cells which have microvilli
20 of 31
Loop of henle
A long hair pin loop that extends from the cortex into the medulla of the kidney and back again. It is surrounded by blood capillaries
21 of 31
Distal convoluted tubule
Series of loops surrounded by blood capillaries. Its walls are made of epithelial cells but it is surrounded by fewer capillaries than the proximal tubule
22 of 31
Collecting duct
A tube into which a number a distal convoluted tubule from a number of nephrons empty, It is lined by epithelial cells and becomes increasingly wide as it empties into the pelvis of the kidney

What are the blood vessels associated with each nephron
A tiny vessel that ultimately arises from the renal artery and supplies the nephron with blood, the afferent arteriole enters the renal capsule of the nephron where is forms the glomerulus
25 of 31
What is the Glomerulus
A many branched knot of capillaries from which fluid is forced out of the blood .
26 of 31
The glomerular capillaries recombine to form the
Efferent arteriole
27 of 31
Efferent arteriole
a tiny vessel that leaves the renal capsule. it has a smaller diameter that the afferent arteriole and so causes an increase in blood pressure within the glomerulus.
28 of 31
The efferent arteriole carries blood
away from the renal capsule and later branches to form the blood capillaries
29 of 31
What are the blood capillaries
concentrated network of capillaries that surrounds the proximal convoluted tubule, the loop of henle and the distal convoluted tubule and from where they reabsorb mineral salts glucose and water
30 of 31
What do these capillaries merge together into
venules (tiny veins) that in turn merge together to form the renal vein
