The majority of carbon dioxide produced by our body cells is transported to the lungs :
- Dissolved in the blood
- As bicarbonates
- As carbonates
- Attached to hemoglobin
The Correct Option is B
Solution and Explanation
The majority of carbon dioxide produced by our body cells is transported to the lungs dissolved in the blood as bicarbonates. This is part of the bicarbonate buffer system that helps regulate blood pH.
Therefore, the correct option is (B): As bicarbonates

Concepts Used:
Human Endocrine System
The human endocrine system is a messenger system that balances or controls distant target organs through feedback loops of hormones released by the internal glands of an organism right into the circulatory system. The hypothalamus is the neural control node for all endocrine systems, in invertebrates.
Functions of the Human Endocrine System are:
The endocrine system controls a variety of body functions through hormone release. Hormones are built by the endocrine system's glands and pass throughout the bloodstream to various organs and tissues in the body. Hormones then command these organs and tissues about how to act.
The Endocrine System is in charge of the following bodily functions:
- Metabolic rate
- Development and growth of a human being
- Reproduction and sexual function
- Heart Rate
- Blood pressure
- The appetite is the need to eat
- Controls cycles of sleep and wakefulness
- Controls the temperature of the body
