Listed below are the differences:
Alveoli |
Nephron |
They are small balloon-like sacs found in the lungs |
They are small tubular structures found in the kidneys |
Thick-walled, comprising of a richly supplied network of capillaries |
Made of glomerulus, renal tube and Bowman’s capsule. They possess a cluster of thin-walled capillaries |
Site of exchange pf gases |
Site for filtration |
Carries out the exchange of carbon dioxide and oxygen occurring between blood capillaries surrounding alveoli and the gases in alveoli |
Blood entering in tnto the renal artery into the kidney branches into capillaries in the glomerulus. At the Bowman’s capsule, the solutes and water are shifted to the nephron which them moves to the proximal tube, down to the Henle’s loop |
