munuaisverenkierto

Munuaisverenkierto refers to the blood circulation system within the kidneys. This complex system is essential for the kidneys' primary functions of filtering waste products from the blood, regulating blood pressure, and maintaining electrolyte balance.

Blood enters the kidneys through the renal arteries, which branch into smaller arterioles. These arterioles lead to the glomeruli, tiny clusters of capillaries where filtration occurs. Here, blood is filtered under pressure, forcing water, salts, and waste products into the renal tubules. The filtered blood, now with essential components like proteins and blood cells retained, leaves the glomeruli and flows into venules.

These venules merge to form larger veins, eventually collecting into the renal vein, which carries the filtered blood away from the kidney. Within the renal tubules, the filtered fluid is further processed. Essential substances are reabsorbed back into the bloodstream, while waste products are concentrated into urine. This intricate interplay between arterial and venous blood flow ensures efficient waste removal and vital bodily fluid regulation. The entire process highlights the kidney's critical role in maintaining overall health.
