The heart pumps blood low in oxygen and high in carbon dioxide to the lungs, where blood releases carbon dioxide and picks up oxygen.
Right ventricle.
Lungs and Lungs. Blood that contains carbon dioxide means it is lacking oxygen, and the carbon dioxide was put into the blood as a waste product by all the other organs. The blood then reaches the lungs and exchanges the carbon dioxide for oxygen. The now oxygen-rich blood is transported to the heart where it is pumped throughout the body, and the carbon dioxide is exhaled from the lungs.
the heart is a muscular organ which is as big as our fist. because both oxygen and carbon dioxide have to be transported by blood, the hear has different chambers to prevent the oxygen-rich blood from mixing with the blood containing carbon dioxide. the carbon dioxide rich blood has to reach the lungs for the carbon dioxide to be removed, and the oxygenated bolld from the lungs has to be brought back to the heart. this oxygen rich blood is then pumped to the rest of the body.
Carbon dioxide rich blood, which is red blood cells lacking oxygen but high in carbon dioxide concentration.These blood cells have circulated through the body and given up much of its oxygen while collecting waste carbon dioxide. The pulmonary artery carries this blood from the heart to the lungs, where it picks up a fresh supply of oxygen and eliminates carbon dioxide.
it changes oxygen to Carbon dioxide in the cells and the carbon becomes carboxy heamoglobin
The right side of the heart takes the blood returning from the body and sends it to the lungs. It is high in carbon dioxide and low in oxygen. After the blood goes to the lungs it returns tot he left side of the heart to be pumped back out tot he body and it low in carbon dioxide and high in oxygen.
The right ventricle pumps blood low in oxygen and high in carbon dioxide back to the lungs.
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.
Low level of carbon- dioxide and more level of oxygen.
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.
Pulmonary arteries
The are transported round attached to a molecule called haemoglobin, present in the red blood cells. The blood is then pumped round the body by the heart and Carbon Dioxide is replaced for Oxygen in the lungs and the converse in the body's capillaries.
Both oxygen and carbon dioxide cross the thin lining of the alveolus. Oxygen crosses from inside the lung into the blood and carbon dioxide crosses from the blood into the lung to be exhaled.
