Renal circulation
Renal Circulation
Renal circulation (pronunciation: /ˈriːnəl ˈsɜːkjʊleɪʃən/) refers to the movement of blood from the body organs towards the kidneys for filtration and then back to the body.
Etymology
The term "renal" is derived from the Latin word "renes", meaning kidneys, and "circulation" comes from the Latin "circulatio", meaning a going around.
Process
Renal circulation begins when oxygenated blood travels from the heart through the aorta to the renal arteries. The renal arteries branch into smaller arterioles, which further divide into the glomeruli. Blood is filtered in the glomeruli, and the filtered blood then moves into the renal veins. The renal veins carry the deoxygenated blood back to the heart via the inferior vena cava.
