Yes, oxygen is necessary for the process of respiration in the lungs, where it allows for the exchange of gases and the removal of carbon dioxide from the blood. This helps to oxygenate the blood, which is essential for proper cellular function throughout the body.
If by that you mean where they get their own oxygen, then from nowhere because red blood cells do not need oxygen, they perform all reactions anaerobically.If you mean where they get it to give off for the rest of your body, then its from the lungs.
Yes, unless you're on cardiopulmonary bypass, which oxygenates the blood directly without the need for the lungs. (This is also called a heart-lung machine, since it fulfills the primary purposes of those organs. They're used for heart surgeries.)
The placenta. Deoxygenated blood flows to the placenta where the carbon dioxide is removed and oxygen added. Oxygen rich blood returns to the fetus. Blood is carried to and from the fetus by the umbilical cord.
Because blood from the whole body is carried toward to right auricle
Lungs are the vector through which oxygen can reach blood. Then blood carries oxygen to somatic cells.
You need oxygen in your lungs in order to breathe. Without blood to transport it your lungs would have none and you wouldn't be able to breathe.
It's not so much that the lungs need alot of blood, but more that the blood depends on the lungs. The nature of the lungs allows the blood to pick up and carry oxogen to the rest of the body and the very thin membranes of the lungs allow the exchange of gasses, oxygen into the blood and carbon dioxide out of the blood.
So as to get OXYGENATED by process of OXYGENATION(and not oxidation).
Because you need to do so to survive. Without blood circulating through the lungs, it would not be able to distribute oxygen to areas like muscle groups or the brain, and the body would quickly die.
Right ventricle. Blood gets pumped from the body to the lungs where it is oxygenated then returns to the heart where it is pumped to the the other organs that need oxygen, e.g. the brain.
Blood is the conduit for oxygen around the human body. If the blood did not circulate through the lungs, oxygen could not be carried around the body. Added to that, decreasing the amount of carbon dioxide is also an essential function of the lungs; the deoxygenised blood needs to relieve itself of the carbon dioxide and collect the oxygen again. The carbon dioxide is then breathed out via the lungs.
The lungs have a large number of blood vessels because blood vessels carry oxygen to the lungs and the lungs need a lot of oxygen.Because it makes the transfer of oxygen from the lungs to the bloodstream quicker.
Beacause the Heart pumps blood & oyxgen throughout your body, & your lungs use oxygen to keep your heart beating. If you want more information about this subject, you should probably ask your doctor. They would know this.
Of course the heart needs lungs. without them the heart wouldn't be able to pump because it needs to take in oxygenated blood and pass through the heart and become oxidized.
lungs are tubes that transfer blood from your heart to your lungs and other parts of your body. (doesn't need to be improved)
Heart has two sides (4chambers) separated by a septum.One side it collects the impure blood ie from all the parts of our body and pumps it to lungs. At lungs through alveoli the co2 diffuses out and oxygen enters the blood. this pure blood (oxygenated blood) enters the other side of heart from where it is pumped to all body parts AND cycle continues.
