it occurs somewhere in the lungs. sorry, i cant get anymore specific than that. sorry, though. :o(
RESPIRATORY
Ericaemily8's improved answer (instead of her's) (The one above mine is someone elses):
It happens at the capillaries, the red blood cells carry the Carbon Dioxide to the capillaries which dispose of it in the human body, that is why you have gas. The capillaries which had oxygen to start with then give the oxygen to the red blood cells which carry it all around your body, mostly your heart.
What else can I help you with?
Why does the blood that flows to the fish's heart lack oxygen?
It's because a process called gas exchange has taken place in the fish's body. Oxygenated blood is pumped throughout the body, and the cells in the body take out oxygen and put in carbon dioxide (gas exchange). The blood returning to the heart of the fish is deoxygenated, and it will have to eventually go to the gills. There, the carbon dioxide (CO2) will get dumped into the water and oxygen (O2) will be picked up from the water at the same time in another gas exchange.
What does the blood carry back to the lungs?
The blood carries carbon dioxide back to the lungs and oxygen out of it
What is deoxygenated blood?
it is blood that is rich in carbon dioxide rather than oxygen on the way back to the heart . the oxygen has been delivered to the body and carbon dioxide has replaced the oxygen. Blood that has released its oxygen. It is dark red in color with a tinge of blue. It is a common misconception that deoxygenated blood is blue. Oxygen bonds to hemoglobin in the blood cells and is transported to where it is needed in the body where it exchanges with carbon dioxide. Deoxygenated blood is found in veins and in the pulmonary artery.
Why does the veins contain more carbon dioxide than the artery?
Here is how it works.You breathe in oxygen, the blood around your lungs picks up that oxygen and goes to your heart (left part) which pumps it to your entire body.As the blood gives oxygen to your tissues, your tissues give carbon dioxide in return because it is a waste product that you need to get rid of.This blood then returns to your heart (the right part) so that it would be pumped back to the lungs where it gives off the carbon dioxide (which is exhaled by your lungs) and takes a new dose of oxygen so the cycle begins again.Therefore your heart functions in 2 ways simultaneously, it pumps blood that has oxygen to your body, and blood that has no oxygen (but has carbon dioxide) to your lungs.
Do arteries contain more oxygen or carbon dioxide than veins?
Arteries carry blood away from the heart and veins carry blood into the heart. Blood moving from the heart to the lungs through the pulmonary artery has less oxygen than blood moving from the lungs to the heart through the pulmonary vein, but most arteries carry oxygen-rich blood with little carbon dioxide, and most veins carry deoxygenated blood with carbon dioxide and other wastes.
Where does the exchange of oxygen carbon dioxide in the blood happen?
The exchange of oxygen and carbon dioxide in the blood occurs in the capillaries surrounding the alveoli in the lungs. Oxygen diffuses from the alveoli into the blood, while carbon dioxide moves from the blood into the alveoli to be exhaled.
What does blood do when you breathe?
Exchange carbon dioxide and oxygen
Where does the exchange of oxygen and carbon dioxide between the air and blood occur in humans?
The exchange of oxygen and carbon dioxide between the air and blood occurs in the alveoli of the lungs. Oxygen from the air diffuses into the blood in the capillaries surrounding the alveoli, while carbon dioxide from the blood diffuses into the alveoli to be exhaled.
What is the name given to the exchange of oxygen and carbon dioxide?
The exchange of oxygen and carbon dioxide between the lungs and bloodstream is known as respiration. This process occurs in the alveoli of the lungs, where oxygen is taken in and carbon dioxide is removed from the blood.
External respiration refers to the exchange of oxygen and carbon dioxide between?
External respiration refers to the exchange of oxygen and carbon dioxide between the lungs and the blood in the pulmonary capillaries. This process allows for oxygen to be taken up by the blood and carbon dioxide to be removed from it.
Where does carbon dioxide exchange with oxygen?
Carbon dioxide and oxygen exchange primarily in the lungs during respiration. Oxygen enters the bloodstream from the lungs, while carbon dioxide is removed from the bloodstream and exhaled out of the body. This exchange occurs in the alveoli, small air sacs in the lungs where oxygen from the air is absorbed and carbon dioxide from the blood is released.
Capillaries exchange food oxygen and what?
They exchange water, oxygen and carbon dioxide, as well as nutrient and waste chemical substances between blood and surrounding tissues.
Where the exchange of oxygen carbon dioxide and wastes take place?
The exchange of oxygen, carbon dioxide, and wastes takes place in the lungs during respiration. Oxygen is taken up by the blood from the air in the lungs, while carbon dioxide and wastes are released from the blood into the lungs to be exhaled out of the body.
What two gases are exchange in the cell?
oxygen and carbon dioxide. oxygen is delivered by the blood into the cell and oxygen from the cell is is given to the blood in exchange to be expelled by the lungs.
Where does blood exchange carbon dioxide for oxygen in the mammalian circulatory system?
the lungs
Does the exchange of carbon dioxide depend on the concentration of oxygen in the alveoli and the blood?
No. It depends on the concentration of carbon dioxide in the alveoli and the blood. The concentration of carbon dioxide in the capillaries of the alveoli is higher than the concentration of carbon dioxide in the air, so carbon dioxide in the capillaries of the alveoli diffuses out of the capillaries into the alveoli of the lungs and is exhaled.
How do capillaries exchange substances between the blood and the tissues?
Oxygen and Carbon Dioxide.
