kidney questions Flashcards
what products leave the kidney
ions, water and urea
what is osmoregulation
is the control of water around the body
what is ultrafiltriomn
Blood from the Renal artery flows through the glomerulus
High blood pressure squeezes out products and glucose out of the blood into bowman capsule
Membrans in capsule act like filters, so big molecules like proteins and blood cells are not squeezed out.
what is the filtered liquid from ultrafiltration know as?
the glomerular filtrate
why is there no glucose in urine
Glucose is reabsorbed back into the blood by active transportation
where are the wast products stored before being realised
stored in the bladder before being realised via the uretha
what happens when someone is dehydrated
the brain detects a water loss so the pituitary gland realises more ADH so the ADH makes the kidney reabsorb more water so the urine is more concentrated
what happens when there is a water gain
the brain detects that there is a water gain so the pituitary Galen releases less ADH
so less ADH means the kidney reabsorbs less waters so urine is more pale
