Answer:
"Alveoli and Nephrons" are the respiratory unit of lungs and excretory unit of the kidney, respectively.
Explanation:
Alveoli are the respiratory unit of lungs. The exchange of gases in the human body takes place in alveoli. They are tiny air sacs ranging up to 350 million in number in each human lung.
Nephron is the term used for the excretory unit of the kidney. It is the structure responsible for creating urine while the waste substances present in the blood are expelled. A kidney contains about 1,000,000 nephrons.
