Answer:<\/strong> There are around 480 million alevoli per lung, or each kidney has 1.1 million nephrons. Our human body relies on these structures to maintain its essential functions. The alveoli in the lungs and the nephrons in the kidneys play a significant role in respiration and excretion, respectively. The alveoli ensure proper exchange of oxygen and carbon dioxide, and that the blood contains enough oxygen. On the other hand, the nephrons would filter the blood and remove the waste. This maintains the fluid balance. <\/p>\n\n\n\n

Structure of Alveoli in the Lungs<\/h2>\n\n\n\n

What is the structure of alveoli? Alveoli are tiny balloon-like sacs situated at the ends of the bronchioles in the lungs. Each lung has millions of alveoli that allow a vast surface area for gas exchange. The walls of alveoli are very thin (around 0.2- 2 micrometres to be precise!) and are surrounded by a network of capillaries. This thin barrier facilitates the proper diffusion of gases between the air in the alveoli and the blood in the capillaries.<\/p>\n\n\n\n

Functioning of Alveoli in the Lungs<\/h2>\n\n\n\n

Alveoli are mainly known to perform 1 function- gas exchange.  The oxygen that you breathe in is diffused through the alveolar walls into the blood. On the other hand, the carbon dioxide from the blood diffuses into the alveoli to be exhaled. This process is important to maintain the oxygen supply and to remove the CO2, a waste product of metabolism.<\/p>\n\n\n\n

Structure of Nephrons in the Kidneys<\/h2>\n\n\n\n

The functional units of the kidneys are called nephrons. Each kidney contains around 1 to 1.5 million nephrons. A nephron mainly has 2 parts. That is- the renal tubule, and the renal corpuscle.<\/p>\n\n\n\n
