Which of the following parts of the human body releases carbon dioxide, brought in by the blood, from the rest of the body?
Answer & explanation
Correct answer: option 2
The correct answer is Option (2)-Alveoli
The part of the human body that releases carbon dioxide, brought in by the blood, is the Alveoli. Alveoli are tiny air sacs in the lungs where the exchange of oxygen and carbon dioxide occurs during the process of respiration. Oxygen from the inhaled air is transferred to the blood, and carbon dioxide from the blood is released into the alveoli to be exhaled out of the body.
