Oxygen is transported around the body by binding to hemoglobin in red blood cells, which then circulate through the bloodstream to tissues that need oxygen. Carbon dioxide is transported mostly in the form of bicarbonate ions in the blood, with a smaller amount carried bound to hemoglobin or dissolved directly in plasma.
What else can I help you with?
What process exchanges O2 and CO2?
The process that exchanges O2 and CO2 is called respiration. In animals, oxygen is inhaled into the lungs, where it diffuses into the bloodstream and is transported to cells for cellular respiration, producing energy. During this process, carbon dioxide, a waste product, is produced and transported back to the lungs, where it is exhaled. In plants, a similar exchange occurs during photosynthesis, where CO2 is taken in and O2 is released.
Do CO2 bind to hemoglobin in the same binding site as O2?
No, carbon dioxide (CO2) binds to a different site on hemoglobin than oxygen (O2). CO2 primarily binds to the amino groups of the protein portion of hemoglobin, forming carbaminohemoglobin. This is an important way that CO2 is transported in the blood.
What tissues will give co2 to the blood in exchange for o2?
Tissues throughout the body, particularly those with high metabolic activity such as muscles and organs, will give carbon dioxide (CO2) to the blood in exchange for oxygen (O2). This exchange occurs primarily in the capillaries, where oxygen is delivered to tissues, and CO2, a byproduct of cellular respiration, is transported back to the bloodstream. The process is facilitated by diffusion, allowing gases to move from areas of higher concentration to areas of lower concentration.
Which way would O2 and CO2 diffuse during internal respiration?
O2 would diffuse into the cells, and CO2 would diffuse into the systemic capillaries.
What is the balanced chemical reaction of CO2---CO O2?
This reaction is:2 CO2 = 2 CO + O2
How is oxygen and carbon dioxide transported in humans?
O2 and Co2 are transported throughout human body by blood. 97% of O2 combines with haemoglobin of RBCs to form oxyhaemoglobin within the lungs. The oxyhaemoglobin then gives out O2 to all the cells. The remaining 3% gets dissolved in blood plasma. 70% of CO2 gets dissolved in blood plasma to reach the lungs from the tissues. The remaining contents of Co2 then combines with haemoglobin to form carboxyhaemoglobin to reach the lungs from the tissues.
What substance needed by the body cells enters the body through the lungs?
O2 and Co2, but we breathe out the Co2 again + the O2 which is converted in more Co2
What process exchanges O2 and CO2?

Why do you have a lungs?
to expel CO2 from your body and to allow O2 into your bloodstream
What are the functions of blood in respiration?
Blood in the body carried respiratory gases (i.e. O2 and CO2) around the body to cells where it's needed for cellular respiration.
Three major characteristics of the respiratory system?
1)Breathing2) Transport of O2 from the lungs to the rest of the body; transport of CO2 from the tissues back to the lungs3) O2 diffuses from Red Blood Cells into body cells; CO2 moves into the blood
What tissues will give co2 to the blood in exchange for o2?
Tissues throughout the body, particularly those with high metabolic activity such as muscles and organs, will give carbon dioxide (CO2) to the blood in exchange for oxygen (O2). This exchange occurs primarily in the capillaries, where oxygen is delivered to tissues, and CO2, a byproduct of cellular respiration, is transported back to the bloodstream. The process is facilitated by diffusion, allowing gases to move from areas of higher concentration to areas of lower concentration.
Where does the blood go after it was pump to the body?
it will go back to the lungs carrying CO2 to exchange with O2
What describes the role of lungs in gas exchange A takes in O2 from blood B produces CO2 as a cellular respiration waste C extracts O2 from the atmosphere for body cells D gives CO2 to capillaries?
It extracts oxygen from the atmosphere for use by body cells.
Which way would O2 and CO2 diffuse during internal respiration?
O2 would diffuse into the cells, and CO2 would diffuse into the systemic capillaries.
What gas does the body require And what gas does it produce?
Requires: O2 (Oxygen) Produces: CO2 (Carbon Dioxide)
