The function of the kidney is to filter blood daily to produce urine that contains waste and extra fluids. Extensions of the cortical tissue contains about one million blood filtering nephrons nephron these are the filtration units in the kidneys medulla inner region of the kidney contains 8 12 renal pyramids. Orientation the image on the left is taken from an area similar to that outlined by the black rectangle.
The adrenal medulla is at the center of each adrenal gland and is surrounded by the adrenal cortex.
The renal medulla is the innermost part of the kidney the renal medulla is split up into a number of sections known as the renal pyramids blood enters into the kidney via the renal artery which then splits up to form the interlobar arteries the interlobar arteries each in turn branch into arcuate arteries which in turn branch to form interlobular arteries and these finally reach the glomeruli. You may be wondering why the epithelium lining some of these tubules look taller and why acidophilic material is present in the lumen of these tubules. It is located just below the rib cage. Cortex the outer region of the kidney.
