Alveoli
Structure
(i) Alveoli are tiny balloon-like structures present inside the lungs.
(ii) The walls of the alveoli are one cell thick and it contains an extensive network of blood capillaries.
Function
(i) 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.
(ii) Alveoli are the site of gaseous exchange.
Nephron
Structure
(i) Alveoli are tiny balloon-like structures present inside the lungs.
(ii) The walls of the alveoli are one cell thick and it contains an extensive network of blood capillaries.

Function
(i) 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.
(ii) Alveoli are the site of gaseous exchange.
Structure
(i) Nephrons are tubular structures present inside the kidneys.
(ii) Nephrons are made of glomerulus, bowman’s capsule, and a long renal tube. It also contains a cluster of thin-walled capillaries.
Function
(i) The blood enters the kidneys through the renal artery which branches into many capillaries in the glomerulus. The water and solute are transferred to the nephron at Bowman’s capsule. Then the filtrate moves through the proximal tubule and then down into the loop of henle. From henle’s loop, filtrate passes into the distal tubule and then to the collecting duct. The collecting duct collects the urine from many nephrons and passes it to the ureter. During the flow of filtrate, some substances such as glucose, amino acids, and water are selectively re-absorbed.
(ii) Nephrons are the basic filtration unit.

1.The alveoli are found in the lungs while the nephron is found in the kidneys.
2.The alveoli aids in the respiratory system while the nephron acts as the functional unit for the endocrine system.
3.The alveoli have one very essential part called the surfactant while the nephron has three important sections to aid its function.
4.The alveoli support the filtering of the air while the nephron supports the filtering process of the blood.
5.The main difference is that the alveoli are the main functional units of the lungs while the nephron is the main unit of the kidney.
