Question Question 13
Compare the functioning of alveoli in the lungs and nephrons in the kidneys with respect to their structure and functioning.
Structure and functioning of alveoli in the lungs and nephrons in the kidneys is compared below:
| Alveoli | Nephron | |
|---|---|---|
| Structure | Alveoli are balloon shaped tiny air sacs present in lungs. | Nephron is cup shaped with long tube like structure present in kidneys. |
| The walls of alveoli are thin, allowing for efficient gas exchange. | Each nephron consists of bowman's capsule, glomerulus and renal tubule. | |
| Function | Alveoli are the site of gaseous exchange. | The nephron is the primary filtration unit of the kidney. |
| Oxygen diffuses from the alveoli into the blood, and carbon dioxide diffuses from the blood into the alveoli to be exhaled. | The blood flows through capillary cluster i.e glomerulus under high pressure which results in collection of filtrate. |
