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.
What else can I help you with?
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.
Name one artery that contain valves?
veins have valves. y
What are the Vessels that carry carbon dioxide back to the heart?
Veins
How are oxygen and carbon dioxide exchanged between the veins and arteries?
Plants give us oxygen we give them carbon dioxide.
What is the difference between an umbilical vein and umbilical artery?
veins carry blood back to the heart, while arteries carry blood away/from the heart. therefore, the arteries carried the oxygen from the heart to the baby via umbilical artery, and the veins picked up waste products such as carbon dioxide and carried it back to the heart via the umbilical vein.
Which blood vessels has the lowest concentration of carbon dioxide?
capillariesVena CavaPulmonary artery
Do veins contain more oxygen or carbon dioxide?
Veins carry blood low in oxygen back to the heart. However, the amount of oxygen in veins is still higher than the amount of carbon dioxide.
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.
Do veins carry a lot of carbon dioxide?
Yes, veins carry alot of carbon dioxide.
What structuere has blood with a high carbon dioxide content?
Venous blood typically has a higher carbon dioxide content compared to arterial blood. This is because carbon dioxide is produced as a waste product of cellular metabolism and is carried back to the heart through veins to be expelled from the body through the lungs.
What is the function of the coronary artery?
The function of the coronary artery is to carry oxygen and nutrients to the myocardium (heart muscle), it does not actually take the carbon dioxide away, (that is the job of the great and small cardiac veins).
Which kind of vein carries blood with high oxygen and low carbon dioxide?
The pulmonary veins are high in oxygen and low in carbon dioxide. All other veins are high in carbon dioxide and low in oxygen.
Name one artery that contain valves?
veins have valves. y
What raw material do the veins of a leaf carry?
carbon dioxide
What are the Vessels that carry carbon dioxide back to the heart?
Veins
How are oxygen and carbon dioxide exchanged between the veins and arteries?
Plants give us oxygen we give them carbon dioxide.
Do Veins have high concentration in CO2?
Usually, but not necessarily. A vein is a blood vessel that is returning to the heart, so it usually has a higher concentration of CO2 than an artery. But in the case of the Pulmonary vein, it is returning to the heart from the lungs, so it has a higher concentration of oxygen than carbon dioxide.
