Question | Answer |
The nephron | This is a structure which runs between the cortex and the medulla of the kidneys. |
The cortex | The outside of the kidneys |
The medulla | The inside of the kidneys |
The renal artery | The tube that blood enters the nephron through. |
The afferent arteriole | A tube which allows blood to flow into the glomerulus. |
The glomerulus | A bundle of capillaries through which ultrafiltration occurs. |
The bowman's capsule | A tubule where the glomerular filrate flows into. |
Capillary endothelium | The membrane of the capillary and it allows amino acids and other small substances through it. |
The basement membrane | The second layer of membrane between the capillary and the Bowman's capsule. Prevents amino acids from entering. |
The epithelium of Bowman's capsule | The final layer of the passage and only allows glomerular filtrate through |
The efferent arteriole | Allows blood to flow through from the glomerulus. It is thin increasing glomerular pressure so ultrafiltraion can occur. |
Proximal convoluted tubule (PCT) | A tube where selective reabsorption can occur. It allows the filtrate to travel to the loop of Henle. |
The descending limb | A tube of the loop of Henle which has walls permeable to water so water an move out by osmosis. |
The loop of henle | This a long tube where water water reabsorption occurs |
The ascending limb | This is the leaving tube of the loop of henle which has walls permeable to Na+ so these ions can move out by facilitated diffusion. |
The distal convoluted tubule | Water also moves out of this tubule. |
The collecting duct | This is a tube which collects urine and alloww it to flow to the ureter |
The ureter | This is a tube which carries the urine to the bladder |
The bladder | The site of urine storage |
The urethra | A tube which carries urine to the outside of the body |
