There are little sacs called Alveoli in the lungs. In these sacs are where gasses are exchanged. Oxygen molecules attach themselves, from the air we breathed in, to the red blood cells, while carbon dioxide molecules unattach themselves from red blood cells and are carried away in the air we exhale.
What else can I help you with?
What if oxygen-rich blood mixes with your oxygen-poor blood?
the quality of our blood that rich with oxygen will become low
Why does blood circulate from the heart to the lungs?
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)
Why is it important for your heart to separate oxygen rich blood from oxygen poor blood?
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.
What makes the blood red and it carries oxygen in the blood?
oxygen is the answer
Do we have oxygen poor blood in your lungs?
no you have oxygen high blood.
How is oxygen transferred to the blood?
oxygen is transferred to the blood by breathing
Why is it important for your heart to keep oxygen rich blood separate from oxygen-poor blood?
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.

What color is oxygen-poor blood?
Oxygen-poor blood is dark red; oxygen-rich blood is bright red.
Which chemical in your blood carries oxygen?
haemoglobin carries oxygen in the blood
Is dark blood oxygen-rich?
Dark red blood is oxygen-poor. Bright red blood is oxygen-rich.
Is blood in veins have oxygen?
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.
