Lungs and Kidney both helps in removing the waste generated in our body.
Alveoli |
Nephron |
Structure |
Structure
|
Alveoli are small sac-like structures present inside the lungs. |
Nephrons are tubular structures present inside the kidneys.
|
The walls of the alveoli are one cell thick and it contains an extensive network of blood capillaries. |
Nephrons are made of glomerulus, bowman’s capsule, and a long renal tube. It also contains a cluster of thin-walled capillaries. |
Function |
Function |
Gas exchange of oxygen and carbon dioxide takes place in the alveoli. |
Nephrons principal function is to control the absorption of water and soluble substances such as sodium salts by filtering the blood, reabsorbing what is required and excreting the rest as urine. |
