Blood is de-oxygenated when it it pumped into the lungs, and after going through the lungs, is now oxygenated.

What collects blood from the lungs?
Blood that has perfused the lungs and is now oxygenated collects into the pulmonary veins to travel back to the heart. Once reaching the heart, oxygenated blood from the lungs enters the left atrium. The left atrium collects blood from the lungs
How does blood travel to the muscle?
Blood moves from the heart. The heart is a pump and it moves the blood to the lungs where it picks up oxygen. The blood carries oxygen by way of large arteries into smaller arteries, into even smaller arterioles, into capillary beds. At this point oxygen is lost into tissues (like muscles). The blood is now low on oxygen and must pick up more in the lungs. It also has to deliver carbon dioxide to the lungs. Back to the capillary bed, into very small venules and then larger veins and larger veins and even larger veins to the heart. Blood moves into the lungs and drops off carbon dioxide and picks up another load of oxygen and back down and around again. The Circulatory System with the heart as a pump.
Which of the three major parts of the circulatory system can now be replaced by surgery?
The heart, individual heart valves, and blood vessels can be replaced by surgery.
What carry the purplish or blue blood back to the heart to get more oxygen?
Veins carry the blood back to the heart and lungs for more oxygen. then the arteries carry the blood that now has oxygen it it to the rest of the body.
Explain how gases are exchanged at the alveoli?
The exchange of carbon dioxide and oxygen occurs in the alveoli. Each alveolus is surrounded by a network of small blood vessels. Like the alveoli, these small blood vessels have extremely thin walls. Blood that enters the vessels has a high level of carbon dioxide, which it picked up from the body tissues. It contains little oxygen. The carbon dioxide leaves the blood and moves through the walls of the blood vessels and alveoli into the lungs. Oxygen from the air in the lungs then passes through the walls of the alveoli and blood vessels and into the blood. The blood, now rich in oxygen, leaves the lungs and travels to the heart. The heart then pumps it to cells throughout the body. The carbon dioxide is finally expelled from the lungs when we exhale.By ichigo kurosaki
What is the function of vein?
Veins are the blood vessels responsible for returning blood to the heart. They carry deoxygenated blood (with the exception of the pulmonary vein) back to the heart whence it goes to the lungs to be re-oxygenated.
What supplies oxygen and eliminates carbon dioxide from the blood stream?
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.
How do the heart and lungs work?
When we breathe in our lungs fill with oxygen rich air. Membranes in the lungs exchange the oxygen from the air with carbon dioxide in the blood. Then we breathe out the spent air to inhale fresh. The blood, now replenished with oxygen, is pumped by the heart through the arteries to all cells in the body where the oxygen is exchanged with the cells for carbon dioxide and returned through the veins to the lungs.
When oxygen moves from the lungs into the bloodstream?
A protein called hemoglobin present in red blood cells is able to bind oxygen molecules. Capillaries surround the alveolar sacs in the lungs where oxygen diffuses into the blood where it is bound by hemoglobin. Now, the oxygen is in the blood.
What happens if the ductus arteriosus does not fully close after birth?
The infant will have abnormal blood flow between the aorta and pulmonary artery (those are the two major blood vessels in the heart). The ductus arteriosus is not needed after birth, since the lungs now fill with air (before birth, the pulmonary artery supplied blood to the lungs and aorta to be sent to the rest of the body).
How does the blood on the right side of the heart differ from the one on the left heart?
On the right side of the heart there is deoxygenated blood which has already been pumped round the body and is now returning to the heart. On the left side of the heart there is oxygenated blood which has just come from the lungs and is about to be pumped round the body Hope this is useful can't quite renember the names and technical words.. sorry...
How does the heart help the lungs do its job in the human body?
The heart is the bodies blood pump. Blood with a low oxygen level enters the heart at the right atria where it is pumped to the right ventricle and then out of the heart through the pulmonary artery ( the only artery in the body that contains low oxygenated blood) and to the lungs. While in the lungs, the blood enters the alveoli where it off loads carbon dioxide molecules and up loads oxygen molecules. The now oxygenated blood returns to the heart into the left atria, is pumped to the left ventricle and then out to the body through the Aorta where it supplies the oxygen to the bodies cells and collects carbon dioxide and other wastes. The cycle begins again.
