Oxygen is primarily transported in vertebrates through the bloodstream, bound to hemoglobin molecules within red blood cells. Hemoglobin has a high affinity for oxygen, allowing it to efficiently pick up oxygen from the lungs and deliver it to tissues throughout the body.
Carbon dioxide, on the other hand, is transported in several ways in vertebrates. Some of the carbon dioxide produced by cells is dissolved in the plasma of the blood. The majority of carbon dioxide, however, is converted into bicarbonate ions by the enzyme carbonic anhydrase within red blood cells. These bicarbonate ions are then transported in the plasma to the lungs, where they are converted back into carbon dioxide and exhaled from the body. Additionally, a small amount of carbon dioxide can also bind to hemoglobin molecules in the blood.
Overall, the transport of oxygen and carbon dioxide in vertebrates is a complex process that involves the coordination of various systems within the body to ensure that cells receive the oxygen they need for energy production and that waste carbon dioxide is efficiently removed from the body.

Oxygen Transport
- Hemoglobin: Majority of oxygen is bound to hemoglobin, a protein in red blood cells.
- Dissolved in plasma: Small amount of oxygen dissolves directly in blood plasma.
- Myoglobin: Some oxygen is stored in myoglobin, a protein found in muscle cells.
Carbon Dioxide Transport
- Bicarbonate ion (HCO3-): Majority of carbon dioxide reacts with water to form bicarbonate ions in red blood cells and plasma.
- Carbaminohemoglobin: Some carbon dioxide combines with hemoglobin to form carbaminohemoglobin.
- Dissolved in plasma: Small amount of carbon dioxide dissolves directly in blood plasma.
Mechanisms of Transport
Oxygen:
- Oxygen diffuses from the lungs into capillaries, where it binds to hemoglobin.
- Hemoglobin transports oxygen through the bloodstream to tissues.
- Oxygen diffuses from capillaries into tissue cells for use in cellular respiration.
Carbon Dioxide:
- Carbon dioxide diffuses from tissues into capillaries.
- Most carbon dioxide is converted to bicarbonate ions in red blood cells.
- Bicarbonate ions diffuse back into plasma and are transported to the lungs.
- In the lungs, bicarbonate ions are converted back to carbon dioxide, which diffuses out into the air.
Additional Features of Transport
- Bohr effect: Increase in acidity (low pH) reduces the affinity of hemoglobin for oxygen, facilitating the release of oxygen in tissues.
- Haldane effect: Increase in carbon dioxide concentration increases the affinity of hemoglobin for oxygen, facilitating the loading of oxygen in the lungs.
- Ventilation and perfusion: The rate of breathing and blood flow to the lungs determine the amount of oxygen and carbon dioxide that is exchanged.
- Hemoglobin: Majority of oxygen is bound to hemoglobin, a protein in red blood cells.
- Dissolved in plasma: Small amount of oxygen dissolves directly in blood plasma.
- Myoglobin: Some oxygen is stored in myoglobin, a protein found in muscle cells.
