Deoxygenated blood is not collected anywhere. Blood is a constantly moving stream - it never stops, as the question implies. The oxygen poor blood goes to the lungs, where it turns oxygenated as it takes up oxygen.
Systemic veins, not to be confused with pulmonary veins, carry oxygen poor blood back to the heart.
The right atrium and ventricle of the heart, as well as veins, contain oxygen-poor blood. The left atrium and ventricle, as well as the arteries, contain oxygen-rich blood. One exception to this is the pulmonary vein and artery, which are reversed - pulmonary artery contains oxygen-poor blood and pulmonary vein contains oxygen-rich blood.
oxygen rich blood gets pumped out of your heart to your arteries which carries the blood to your muscles. then your muscles use the oxygen. oxygen poor blood goes into your veins to go back into your heart. then it goes through a cycle that takes your blood to your lungs, to get oxygen. this process is repeated.
it turns from oxygen rich (oxygenated) blood to oxygen poor (deoxygenated) blood
The vessel that conveys oxygen-poor blood from the right ventricle is called the pulmonary artery.
Venous blood is oxygen poor (in comparison with arterial blood).
Oxygen-poor blood is dark red; oxygen-rich blood is bright red.
Oxygen poor blood
poor
no you have oxygen high blood.
The pulmonary artery carries oxygen poor blood and the pulmonary vein carries oxygen rich 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.
The right chambers have oxygen poor blood. The right atrium receives oxygen-poor blood from the body circulation, and the right ventricle pumps it to the lungs.
blood in the most veins are oxygen poor blood because it gives greenish colour.
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.

Blood entering the left ventricle is rich in oxygen. In contrast, oxygen-poor blood enters the right ventricle.
