Blood circulation to and from the kidney
Kidney as a tool to filter the blood, the kidney is
organ which has blood vessels very much.
Blood into the kidney comes from the abdominal aorta
(large abdominal arteries) which later branched off into
renal arteries (renal arteries) and then enter into
kidney through the renal basin (hilar renal). Renal artery
before entering the kidney is usually branched into 2 (two)
ie one in the anterior (front) and other kidney
posterior (rear). Once entered into dlam kidneys, renal artery
gives off the artery interlobaris, arcuata artery, the artery
interlobularis, afferent arteriole, glomerulus, efferent arteriole, capillary
peritubuler (juxta glomerulare), interlobularis vein, vena arcuata,
interlobularis vein, renal vein.
In the medulla found venulae rectae, where the blood
flowing back into the arcuate veins. These vessels
containing blood that have been filtered in the glomeruli, which
an important role in maintaining interstitial tissue osmolarity high medulla.
Capillaries and the outer cortex of kidney capsules united
form the veins that lead into stelata veins
interlobularis. Veins follow the same way as
artery. Blood from the veins into the interlobularis flow venavena
arcuate, and from here to interlobaris veins. Interlobaris veins which form the renal vein blood and left kidney.
Afferent arterioles
Efferent ateriol wall contains smooth muscle
able to change the lumen diameter, whereas the lumen ateriol
afferents remains constant at the center line, because the smooth muscle cells surrounding a role in secretion rather than the role
contraction. Glometulus the blood capillaries. Glomeruli
contains arterial capillaries
