Blood containing oxyhemoglobin returns to the heart?

Answer 1

Blood returning from its cycle through the body is not oxygenated. Once the blood reaches the heart it is then sent to the lungs, where it is oxygenated, then returns to the heart to be sent through the body.

Answer 2

Yes, hemoglobin in the blood is pumped to the lungs where it reacts with oxygen to form oxyhemolobin, then it returns to the heart in the pulmonaryvein (the only oxygen carrying vein in the body) where it is pumped around the body.

Answer 3

The oxygenated blood is returned to the heart to the atrium (left if I remember right) and it also feeds the vessels to the heart muscle itself to keep it alive. When a heart muscle has a myocardial infarction that means the heart vessels are not feeding oxygen to the heart muscle and the muscle area affect is getting necrotic or has already become that way (the more serious type of infarction). The heart pumps oxygenated blood through out the entire body to keep the body alive. If the body fails to receive the oxygen it begins to die off. It also needs waters. We must have water and oxygen in our entire body and our heart and blood.

Answer 4

all blood is carried to all parts/organs of the body by arteries and by veins. arteries typically carry oxygenated blood to the muscles and tissue throughout the body, while veins return deoxygenated blood back to the heart. now to answer your question. when the deoxygenated blood reaches the heart it is pumped to the lungs via the pulmonary artery (correct, deoxygenated blood to the lungs). the deoxygenated blood is then revitalized (oxygenated) via the alveoli/capillary beds in the lungs. this oxygenated blood is then sent back to the heart via the pulmonary vascular system. in the final outcome in answer to your question: oxygenated blood is returned to the heart via the pulmonary vein.

Answer 5

Oxygenated blood comes from the lungs and back to the heart by way of the 4 pulmonary veins.
