Through the vena cava. Blood enters the heart at the right atrium when from the systemic circulation. It Gets here through the superior and inferior vena cava and the coronary sinus. From the pulmonary circulation it enters the left atrium from the pulmonary vein.
When blood leaves the lungs through the pulmonary veins, it returns to the heart and enters the left ventricle.
Blood passes through the bicuspid valve and enters the left ventricle.

The kidney receives blood through two renal arteries. One artery supplies blood to left kidney while the other supplies blood to the right kidney. Within the kidney, each artery branches out into arterioles and finally the afferent arterioles.
Oxygenated blood enters the kidneys through the renal arteries. Blockage of these arteries can affect kidney function as well as blod pressure.
Blood enters the kidney through the Renal artery.
Blood enters the kidney through the renal artery. It is then cleaned as it goes through the tiny filters called nephrons.
The nephron process is where the blood enters the glomerulus and is absorbed. It is then processed through the kidney's and turned into urine.
Heart goes from the right side, other wise you might have the disease that makes your heart pull from the left side.

Blood flows to the kidney through the renal artery. Once in the kidney the blood flows through a series of smaller and smaller arteries until it gets to the glomerulus. The glomerulus filters blood and to be very simplistic creates a filtrate of the blood or "urine". This urine then flows through a series of progressively bigger tubules and ducts until it gets to the renal pelvis. At this point urine exits the kidney, it enters the ureter (long tube connecting kidney and bladder), and flows into the bladder where it is held until one desires to urinate. At this time urine flows out of the bladder and into the urethra. The urethra connects the bladder to the outside of the body.
Two blood vessels enter and leave each kidney. The renal artery enters each kidney and the renal vein exits each kidney for more information see entrancei.com
Blood is purified when it enters a nephron through the artiole, impurities are filtered out and emptied into the collecting duct. The purified blood exits the nephron through the venule. Hope it helps ;)
