| Alveoli | Nephrons |
| Structure | Structure |
| Alveoli are tiny balloon-like structures present inside the lungs. | Nephrons are tubular structures present inside the kidneys. |
| The walls of the alveoli are one cell thick and they contain an extensive network of blood capillaries. | Nephrons are made of glomerulus, a Bowman’s capsule, and a long renal tube. |
| Function | Function |
| The exchange of O2 and CO2 takes place between the blood of the capillaries that surround the alveoli and the gases present in the alveoli. | The blood enters the kidneys through the renal artery. The blood is entered here and the nitrogenous waste in the form of urine is collected by collecting duct. |
| Alveoli are the site of gaseous exchange. | Nephrons are the basic filtration unit. |
