Venous blood from body tissues is deoxygenated. It flows into the heart at the right atrium, through the tricuspid valve, and into the right atrium. Then it gets pumped to the lungs through the pulmonary semilunar valve. It becomes oxygenated in the lungs, then goes to the left atrium of the heart where it passes through the bicuspid valve and then is pumped through the Aortic semilunar valve where it becomes arterial blood.
pulmonary arterial blood as it has moce CO2 than venous
arterial
Arterial blood is under direct pressure from the heart and is oxygen rich, which venous blood is oxygen poor and is under low pressure.
The arterial and venous systems are connected in the body tissues by capillaries, and also in the heart.

venous and arterial
Venous and arterial
The influx of carbon dioxide in venous blood.
This situation happen because VOLUME OF RBCs in venous blood is high. The volume is increased from arterial blood to venous blood because chloride shift that occurred;relate with increase of carbon dioxide in blood.
Venous blood is oxygen poor (in comparison with arterial blood).
it has more oxygen than arterial blood
Arterial blood have more Oxygen and venous blood have more CO2 except the pulmonary vien which carry oxygenated blood to the heart for pumping to arteries.
