Our basic function is kidney sifting through all blood, picking out things we no longer
needed and putting them out through the urine. Because all the blood and things inside
the blood is constantly getting ﬁltered by the kidneys, the kidney will maintain BP and
BV, and solute concentration
Kidneys are where we make urine.
It will go down to the ureter, and these will go to the urinary bladder where it is stored
until it ﬁlls up then down to the urethra.
Renal artery brings oxygen rich supply to kidneys, renal vein carries away
deoxygenated blood and waste products.
Basic structure: cortex, medulla, and pelvis.
Right at the cortex and edge of medulla, the renal pyramids is where we start ﬁltering
We do our ﬁltration in the renal pyramid in medulla, the little ends of the pyramid where
urine comes out is called the papillae of the pyramid, they then come into the openings
called minor calyx and a few of these form together to make a major calyx, which form
together to form the renal pelvis.
Once the urine is there, it’ll go out through the ureter.
We ﬁlter blood to maintain homeostasis, and in the blood it carries all our nutrients and
solutes, the kidney is going to consistently check the blood and alter the level of all
things we don’t need
The area where the ureter and blood vessels are coming out is called the hilum
Kidneys are protected by the ribs.
