Pulmonary arterial system has high pressure but low oxygen concentration.
pulmonary arteries
pulmonary vein or lungs
pulmonary veins
The pulmonary artery carries blood away from the heart and it is low in oxygen.
Low oxygen/de-oxygenated blood is carried by:all the veins (except the pulmonary vein)the pulmonary artery.
The pulmonary artery carries blood away from the heart and it is low in oxygen.
The pulmonary artery carries blood away from the heart and it is low in oxygen.
Blood in this case is low in oxygen.
As blood passes through lungs, there is exchange of oxygen and carbon bi oxide, from high concentration to low concentration and oxygen enters the blood from air to blood to make it oxygen rich.
They are low in oxygen.
High in carbob dioxide and low in oxigen
