Respiratory
No - not really anyhow. Oxygen is brought to the lungs by breathing in air. The lungs function as an exchange system which loads up the red blood cells with oxygen. So lungs give oxygen to red blood cells which then deliver the oxygen to all the parts of the body.
loads of oxigen
the quality of our blood that rich with oxygen will become low
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.
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)
their is loads of it

Oxygen never fully dissociates from the haemoglobin in the red blood cells. There is a lot more oxygen in arterial blood, but there is still oxygen in veinal blood too.
Oxygen-poor blood is dark red; oxygen-rich blood is bright red.
Dark red blood is oxygen-poor. Bright red blood is oxygen-rich.
haemoglobin carries oxygen in the blood
