Not always. The pulmonary artery and the pulmonary vein reverse the general roles of O2 rich and poor blood. The pulmonary artery carries O2 poor blood to the lungs and the pulmonary vein carries O2 rich blood back to the heart in order to be sent to the rest of the body.
The blood that enters the right atrium is oxygen-poor, as it has already delivered oxygen to the body's tissues and organs and collected carbon dioxide waste. The blood then flows to the lungs where it picks up oxygen and gets rid of carbon dioxide through the process of respiration.
Blood
The human heart has 4 chambers. Blood with no O2 goes to the heart then is pumped to the lungs to receive O2 then the blood is sent back to the heart where it is then pumped to the rest of the body.
Nothing does. Carbon monoxide is toxic. If your blood is rich in it, you will soon be dead. Veins generally carry blood that is rich in carbon dioxide.
Oxygen Poor
The pulmonary veins carry O2 rich blood to the heart.

O2 poor. Pulmonary veins carry O2 rich blood.
the artries always carry O2 rich blood but the exception to this rule is pulmonary artery which carries o2 poor blood.pulmonary artery carries O deficit blood to the lungs it is exception to artries which always carry O rich blood to organs of body.
o2 poor blood
Heart pumps O2 rich blood to body through artries.
Yes, in children also. The pulmonary veins carry oxygen rich blood from the lungs to the heart.
To be "oxgenated" means the blood holds oxygen, so "oxygenated blood" carries O2 laden blood.
The left ventricle sends O2 rich blood through the aortic valve out the aorta back to the systemic circuit.
If my science book proves correct, I believe it is so the O2 rich blood and the O2 poor blood mixing is kept to a minimum.
Arteries always carry blood away from the heart. Veins always carry blood back to the heart. Not all arteries carry high O2 blood. Not all veins carry low O2 blood.
