The veins lead the de-oxygenated blood back to the heart, where it goes through the right atrium, right ventricle, and through the Pulmonary Arteries to the lungs, where gas exchange happens.
Gas exchange is the process of CO2 and O2 swapping. This occurs in the capillaries, filled with blood and CO2, and the alveoli in the lungs. The capillaries wrap around the alveoli, and both capillaries and alveoli have very thin walls (one cell thick), so thin that CO2 and O2 particles can swap around.
When you breathe in, O2 travels into your lungs, through many tubes, to get to the tiny alveoli, where they then move through the alveoli's walls to the capillaries. When you breathe out, the opposite occurs, CO2 is transfered from the capillaries to the alveoli and leaves the lungs, and the body.
The capillaries then take the blood, now filled with oxygen, back to the heart. Then the blood circulates the body. This process is repeated every time you breathe.
Blood cells from the heart flow to the lungs, gather oxygen, and go to "share" the oxygen with the rest of the body.
Blood carried through veins is has no oxygen in it. Veins lead to the lungs and the air we breathe in gets into our veins (of course the carbon is removed leaving only oxygen or O2).
If the oxygen-rich blood and the oxygen poor blood mix the amount of oxygen becomes diluted. The cells and tissues need more oxygen than they will get.
oxygen is the answer
Oxygenated blood is the blood remaining after the oxygen intake by the body from the blood. And than oxygenated blood goes to Lungs and heart with enrich with oxygen for the body.
Blood gets oxygen in the cells. This is part of the body system.
Systemic Arteries carry oxygen rich blood (also called oxygenated blood). Pulmonary Arteries carry oxygen poor (deoxygenated) blood
The blood gets oxygen from the air around us which is made of oxygen. When we breath in, the oxygen is taken into our lungs and then into our blood.
the quality of our blood that rich with oxygen will become low
The oxygen poor blood (not enough oxygen) goes to the lungs to get more oxygen to turn into oxygen rich blood (has plenty of oxygen)
If the oxygen-rich blood and the oxygen poor blood mix the amount of oxygen becomes diluted. The cells and tissues need more oxygen than they will get.
no you have oxygen high blood.
oxygen is the answer
oxygen is transferred to the blood by breathing
If the oxygen-rich blood and the oxygen poor blood mix the amount of oxygen becomes diluted. The cells and tissues need more oxygen than they will get.
If the oxygen-rich blood and the oxygen poor blood mix the amount of oxygen becomes diluted. The cells and tissues need more oxygen than they will get.
Oxygen-poor blood is dark red; oxygen-rich blood is bright red.
haemoglobin carries oxygen in the blood
Dark red blood is oxygen-poor. Bright red blood is oxygen-rich.
