Expert Answer
- Carbon dioxide is essential for internal respiration in a human body.
- Internal respiration is a process, by which oxygen is transported to body tissues and carbon dioxide is carried away from them.
- Carbon dioxide maintains the pH of the blood, which is essential for survival.
- Low concentrationsof carbon dioxide are not harmful. Higher concentrations can affect respiratory function and cause excitation followed by depression of the central nervous system.
- A high concentration can displace oxygen in the air.
