The blood transports carbon dioxide in the form of carbonic acid, which is formed by combining with water in the red blood cells. The dissociation reaction can be represented as:
H₂CO₃ ↔ H⁺ + CO₃⁻
As the pH of the blood decreases, the level of H⁺ ions rises, leading to a shift in the equilibrium backwards in accordance with Le Chatelier's principle. The H⁺ ions are reconverted into carbonic acid, which in effect raises the pH. When the pH exceeds certain levels, the reverse process occurs.
The main function of sugars in living organisms is to supply energy.
Grains, seeds, nuts, and root vegetables are types of COMPLEX carbohydrates that require a LONGER time to be broken down, which helps one feel full for an extended period. Complex carbohydrates are polysaccharides made of chains containing hundreds of monosaccharide units, so they take more time to digest completely.

Answer:
The respiratory system is comprised of specialized organs and structures for gas exchange in both animals and plants. The structure and function of this system differ significantly based on the organism's size, habitat, and evolutionary background. In terrestrial animals, the respiratory surfaces are typically the linings of the lungs. In mammals and reptiles, gas exchange occurs within millions of tiny air sacs known as alveoli, while birds have atria for this process. These tiny air sacs boast an extensive blood supply, ensuring air comes into close proximity with the bloodstream. They connect to the outer environment through airways or hollow tubes, with the trachea being the largest that divides in the chest into two primary bronchi. These then branch further into successively narrower secondary and tertiary bronchi, eventually leading to numerous smaller tubes called bronchioles. In birds, these are referred to as parabronchi. The air needs to be drawn into the alveoli or atria from the outside through the act of breathing, which involves respiratory muscles.
