Low level of carbon- dioxide and more level of oxygen.
Blood coming from the lungs has lower pressure while that from the heart has higher pressure. Blood coming from the lungs also has higher oxygen content and lower carbon dioxide content compared to that coming from the heart.
The heart pumps blood low in oxygen and high in carbon dioxide to the lungs, where blood releases carbon dioxide and picks up oxygen.
Carbon dioxide is at high levels and oxygen at low levels in blood that is being pumped from the heart to 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.
Blood coming from the lungs enters the left side of the heart.
The heart pumps the blood that takes carbon dioxide to the lungs. So, the heart is a necessary element, but isn't the one effectively doing it.
veins
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.
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.
Ariel zapata.... its the lungs.... that's how we breath... in with the oxigen out with the carbon dioxide, i got myspace. for further queations...
Blood containing carbon dioxide flows from veins throughout the body to the heart, and then the heart pumps it to the lungs. Small air sacs (alveoli) in the lungs remove the carbon dioxide from the blood and release it into the lungs where it is exhaled.
The artery that carries blood from the heart to the lungs to pick up carbon dioxide is the pulmonary artery. It transports deoxygenated blood from the right ventricle of the heart to the lungs, where gas exchange occurs, allowing carbon dioxide to be expelled and oxygen to be absorbed. After this process, the oxygenated blood returns to the heart via the pulmonary veins.
