the alveoli in the lungs are present in millions and help in the exchange of gases. The more number of alveoli cause the increase in surface area for easy exchange of gases.
the nephrons are the functional units of the kidney which are also present in millions that filter blood for a healthy living. The nephrons purify blood by taking out the dangerous impurities and absorbing the essential nutrients required by the body again.
