By 3 main mechanisms:
1. As bicarbonate ions (HCO3-)
Carbon dioxide combines with water to form carbonic acid with the aid of the enzyme, carbonic anhydrase. The carbonic acid dissociates into bicarbonate ions and hydrogen ions. Bicarbonate ions are transported via the blood plasma to the alveoli, where the reverse process occurs to revert back to carbon dioxide.
2. Carbaminohaemoglobin
Carbon dioxide combines with haemoglobin to form carbaminohaemoglobin. This is reversible at the alveoli. About 10% is transported this way.
3. Dissolved in blood plasma.
The most straightforward way. Simply dissolve in blood plasma and bring it over to the alveoli. About 5% is transported this way.

Why does oxygen and carbon dioxide move from the alveoli into the blood stream?
Oxygen moves from the alveoli into the bloodstream through diffusion, where it crosses the thin walls of the alveoli and capillaries. Similarly, carbon dioxide moves from the bloodstream into the alveoli for removal when blood with high levels of carbon dioxide comes into contact with alveolar air with lower levels of carbon dioxide.
How do carbon dioxide and oxygen move in and out of cells?
Carbon dioxide diffuses out of cells into the bloodstream and is transported to the lungs to be exhaled. Oxygen is taken up by red blood cells in the lungs and transported to cells where it diffuses into the cells to be used for energy production.
What substances go into the blood in the exchange at capillaries?
In the exchange at capillaries, substances such as oxygen, carbon dioxide, nutrients (glucose, amino acids), waste products (urea, carbon dioxide), and hormones move into and out of the blood. This exchange occurs to ensure that cells receive the necessary nutrients and get rid of waste products.
Where do Oxygen and Carbon dioxide move from high concentration to low concentration?
Oxygen moves from high concentration in the lungs to low concentration in the blood for delivery to tissues, while carbon dioxide moves from high concentration in the tissues to low concentration in the lungs for removal from the body.
What is a small opening on the underside of a leaf through which oxygen and carbon dioxide can move?
Stomata.
Why does oxygen and carbon dioxide move from the alveoli into the blood stream?
Oxygen moves from the alveoli into the bloodstream through diffusion, where it crosses the thin walls of the alveoli and capillaries. Similarly, carbon dioxide moves from the bloodstream into the alveoli for removal when blood with high levels of carbon dioxide comes into contact with alveolar air with lower levels of carbon dioxide.
What carries carbon dioxide wastes away from the cells of the body?
Red blood cells carry most carbon dioxide wastes away from the cells of the body.
How does carbon dioxide move into the blood stream?
Carbon dioxide moves into the bloodstream through a process called diffusion. In the lungs, carbon dioxide from the body's tissues diffuses across the thin walls of the capillaries and into the alveoli, where it is exhaled out of the body when we breathe.
What is the function of the aveoli?
The function of the alveoli is to allow gas exchange with the blood and lungs. It takes in the carbon dioxide and then diffuses it.
What job the lungs perform in eliminating wastes from the body?
Yes, in a way. They take out the carbon dioxide from the blood and put the oxygen back in the blood. The sole purpose of the blood is to get oxygen from the lungs and bring it to other body parts and take the carbon dioxide back to the lungs.
What is the process by which oxygen and carbon dioxide move across the alveoli?
It is the process of simple diffusion. The movement of oxygen from a high level (in the air) to a lower level (in the blood). The opposite occurs for carbon dioxide which is higher in the blood but lower in the air.
How do oxygen and carbon dioxide move into and out of cells?
Oxygen enters cells through diffusion, where it moves from areas of high concentration in the bloodstream to low concentration in cells. Carbon dioxide exits cells through the same process, diffusing from high concentration in cells to low concentration in the bloodstream for removal by the lungs.
How do carbon dioxide and oxygen move in and out of cells?
Carbon dioxide diffuses out of cells into the bloodstream and is transported to the lungs to be exhaled. Oxygen is taken up by red blood cells in the lungs and transported to cells where it diffuses into the cells to be used for energy production.
What gas moves from the heart muscles to the capillaries?
Two primary gases are found in the blood stream. Leaving the capillaries and going out into the tissue is OXYGEN which was carried by the hemoglobin in the red blood cell. Leaving the tissue and entering the capillary is CARBON DIOXIDE or "CO2" which is transported via carbonated water (aka carbonic acid) in the plasma of the blood stream.
What substances go into the blood in the exchange at capillaries?
In the exchange at capillaries, substances such as oxygen, carbon dioxide, nutrients (glucose, amino acids), waste products (urea, carbon dioxide), and hormones move into and out of the blood. This exchange occurs to ensure that cells receive the necessary nutrients and get rid of waste products.
The carbon dioxide cycle is the pathway in which carbon dioxide and oxygen move through the environment?
no because its online somewhere else
Why the dry ice first time the smoke will move up aftera few mins the smoke move downwards?
because of the carbon dioxide in the dry ice because of the carbon dioxide in the dry ice because of the carbon dioxide in the dry ice
