Your lungs, as part of the respiratory system, bring oxygen into your body. Nothing removes carbon dioxide though, it's never in your body per se, the oxygen in your blood cells just gets used when your cells travel through your body, then they go to the lungs which in effect just "recharge" them with oxygen again.
A leaf gives out oxygen through a process called photosynthesis. During photosynthesis, plants use sunlight to convert carbon dioxide and water into glucose and oxygen.
Within the circulatory system gas exchange happens at two places. First within the lungs where it picks up oxygen and gives up its carbon dioxide. Secondly, within the capillary beds of the tissues to deliver the oxygen (and nutrients) and pick up the carbon dioxide to bring back to the lungs.
During photosynthesis, grass gives off oxygen gas (O2) as a byproduct. This oxygen is released into the atmosphere as a result of the plant using sunlight to convert carbon dioxide (CO2) and water (H2O) into glucose and oxygen.
Hemoglobin/haemoglobin (two different spellings of the same thing). It's a protein made up of four separate protein chains, each of which has a heme group, which has as its central feature a porphyrin ring containing an iron atom. This is what gives red blood cells their characteristic color (which is actually more of a dark purple than red when carbon dioxide is bound to the heme groups).
it is called cycle because when we exhale we gives off carbon dioxide, and it is absorb by plants, then after the process called photosynthesis it gives off oxygen to the atmosphere, then now we inhale it and after we inhale we exhale the carbon dioxide and goes to the atmosphere then absorb by plants, gives off oxygen, goes to the atmosphere, then inhale it and so on and so forth . . . . . . . . . . . . . . . for shorth will go back and go back. not like the one way flow of energy that will remain.... . . . . . . . . . . . . . . . . . . . . . . .
blood takes oxygen and gives carbon dioxide to the lungs
It gives up oxygen, and carries out carbon dioxide.
It gives up oxygen, and carries out carbon dioxide.
It gets rid of carbon dioxide, then it takes the oxygen and gives it to cells. Carbon dioxide is cell waste.
The oxygen in it is replaced with carbon dioxide.
Blood gives up carbon dioxide and obtains oxygen in the capillaries within the lungs during the process of gas exchange. In the lungs, carbon dioxide diffuses from the blood into the alveoli to be exhaled, while oxygen diffuses from the alveoli into the blood to be carried to the body's tissues.
blood takes oxygen and gives carbon dioxide to the lungs
Yes we do, we absorb the oxygen and give out carbon dioxide
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.
No, it does everything except picks up oxygen in the LUNGS. It gives up carbon dioxide instead! :)
capillary :)
After delivering oxygen to tissues throughout the body, red blood cells pick up carbon dioxide, a waste product produced by cells during cellular respiration. Carbon dioxide is then transported back to the lungs where it can be exhaled from the body.
