THE KIDNEY
Each kidney is a bean shaped organ, which is about 10 cms long.
They lie in the abdominal cavity being attached with the dorsal
body wall on either side of the vertebral column. Each kidney is
enclosed in a thin, membraneous covering called peritoneum lo-
cated on the top of each kidney is adrenal gland. The kidneys re-
ceive blood through paired renal arteries, which directly arise
from the dorsal aorta. The blood is drained out from each kidney
Caption
by a renal vein. Both renal arteries enter and renal veins leave
kidney kidney at the site called hilus.
THE STRUCTURE OF KIDNEY
A longitudinal section of kidney shows that it consists of two dis-
tinct regions; an outer darker region, the cortex and an inner
lighter region, the medulla.The medulla consists of many cone
shaped structures called pyramids.Urine is dropped continuously
from the tips of pyramids into funnel shaped spaces called pelvis
of the ureter.
Nephron: Each kidney is composed of about a million microscopic
tubules or nephrons.It is regarded as structural and functional
unit of kidney, which performs osmoregulation as well as excre-
tion.
