Entire kidney
Blood flows through the kidneys in the following systematic way. It flows from Renal Artery to segmental artery to lobar artery to interlobar artery to arculate artery to interlobular artery to afferent arteriole to glomerular capillaries to efferent arteriole to peritubular capillaries to vasa recta to interlobular vein to arcuate vein to interlobar vein and finally to the renal vein.
Generally blood from the capillaries flows into venules which lead into larger veins and is then pumped to the heart. However there are a few exceptions where capillaries lead from one artery to another artery, but this only happens in the glomerular capsule of the kidney and the hypothalamus.

The primary artery that blood flows out of the heart to the rest of the body is the aorta. The aorta is also the largest artery of the body.
Blood enters the kidney through the renal artery, which branches from the abdominal aorta. Once in the kidney, the renal artery further divides into smaller arterioles, ultimately leading to the glomeruli, which are a network of capillaries. Here, filtration occurs, allowing waste products and excess substances to be removed from the blood for urine formation. The filtered blood then continues through the renal veins, returning to circulation.

Artery and vains
After leaving the subclavian artery, blood flows into the axillary artery as it passes under the clavicle and into the armpit region. From the axillary artery, it continues into the brachial artery as it travels down the upper arm. The brachial artery further branches into the radial and ulnar arteries at the elbow, supplying blood to the forearm and hand.
