Not: Carbonate ions CO3
Corrected:
Carbon dioxide, when dissolved in blood, is almost exclusively present as hydrogen carbonate ions: HCO3-
CO2 + H2O --> H2CO3
but this reaction is followed by two possible equilibria:
H2CO3 <-->> HCO3- + H+
HCO3- <-- CO32- + H+
Only at pH above 10.25 there is a significant amount (50%) of carbonate (CO32-) present, but blood can NEVER reach that high pH value.
When carbon dioxide (CO2) dissolves in water in blood cells, it forms carbonic acid (H2CO3). Carbonic acid then dissociates into bicarbonate ions (HCO3-) and hydrogen ions (H+). This reaction is part of the bicarbonate buffer system, which helps maintain the pH balance of blood.
Red blood cells take carbon dioxide (CO2) away from body tissues. The carbon dioxide is then transported to the lungs where it can be exhaled.
Red blood cells carry most carbon dioxide wastes away from the cells of the body.
Venous blood is loaded with carbon dioxide and low in oxygen Arterial blood is rich in oxygen with little carbon dioxide
In arterial blood cells Oxygen. In venous blood cells Carbon Dioxide.
carbon dioxide is expelled from cells into the blood stream, carried to the lungs, and exhaled.
Carbon dioxide, made by the cells as they do their work, moves out of the cells into the capillaries, where most of it dissolves in the plasma of the blood. Blood rich in carbon dioxide then returns to the heart via the veins.
Carbon dioxide and water
Red blood cells take carbon dioxide (CO2) away from body tissues. The carbon dioxide is then transported to the lungs where it can be exhaled.
By the esophagus and then it gets into your blood cells.
The primary function of white blood cells is to fight infection. Red blood cells carry oxygen from the lungs to the body tissues, and carbon dioxide as a waste product away from the tissues and back to the lungs.
Red blood cells carry most carbon dioxide wastes away from the cells of the body.
Blood carries carbon dioxide out of cells.

Lungs
Carbon dioxide rich blood, which is red blood cells lacking oxygen but high in carbon dioxide concentration.These blood cells have circulated through the body and given up much of its oxygen while collecting waste carbon dioxide. The pulmonary artery carries this blood from the heart to the lungs, where it picks up a fresh supply of oxygen and eliminates carbon dioxide.
