Ans: Other than being dead....the blood viens show/turn blue...as opposed to red(oxygenated)
Anywhere along the systemic side of the circulation, like veins, right atrium, right ventrical, pulmonary artery etc.
the oxygenated and deoxygenated blood would mix.
The deoxygenated blood and the oxygenated blood would mix.
If you're referring to hypo-oxygenation, an arterial stick would be a surefire method. Id you mean naturally, non-pathological de-oxygenation as part of the normal circulatory process, venous blood will show this and a sample from a vein will do the trick.
In the Pulmonary Circulation!
Arteries carry oxygenated blood away from the heart. Arteries probably CAN carry deoxygenated blood if a person draws blood from a vein, then injects it into an artery. That would be very stupid though.
Firstly ,Heart pumps deoxygenated coming from body, to the lungs and then the deoxygenated blood turns to oxygenated inside the lungs and after that it comes back to heart . After this, heart again pumps those oxygenated blood coming from lungs, to the body parts .So iIf there would be only one pump system then heart would be as hollow and all the deoxygenated and oxygenated blood would be mixed up inside the heart.
in the left atrium u will always find deoxygenated blood ( the blood having less quantity of oxygen )
The circulatory system carries oxygenated blood to the body. ^more specifically, the arteries in your circulatory system do. Circulatory system is the container for blood. Artery- 02 rich blood Venous- 02 poor blood
The jugular veins are found in your neck, they carry deoxygenated blood from the head to the heart.
Do you mean oxygenated blood? If so, then this would be arteries. This would be because all arteries do so except for the one going to your lungs (pulmonary artery) as it carries deoxygenated blood to the lungs and the pulmonary vein carries oxygenated blood to the heart. Of course, all other veins carry deoxygenated blood around the body. Maybe this is what you meant?-dragon934-
Oxygenated blood is present in right Atria. Oxygenated blood are more darker than deoxygenated blood. I bet you If you write this answer in test you would get full marks.
