the androgerodamus vein has the most
The umbilical vein carries oxygen-rich blood from the placenta to the fetus, making it the fetal blood vessel with the highest oxygen concentration.
The pulmonary vein carries blood with the highest oxygen concentration, as it transports oxygen-rich blood from the lungs to the heart. This freshly oxygenated blood is then pumped out to the rest of the body by the heart.
pulmonary veins
pulmonary vein or lungs
The blood in the pulmonary veins contains the highest concentration of oxygen since it has just been oxygenated in the lungs before returning to the heart to be pumped to the rest of the body.
Left atrium.
the coronary arteries Which blood vessels contain blood that is higher in oxygen? -Pulmonary Veins
Pulmonary arterial system has high pressure but low oxygen concentration.
pulmonary vein, as it carries oxygen-rich blood from the lungs to the heart to be distributed to the body tissues.
Pulmonary veins, as they carry freshly oxygenated blood from the lungs back to the heart for distribution throughout the body.
Oxygen diffuses from an alveolus to the blood around it because of the concentration gradient between the high oxygen concentration in the alveolus and the lower oxygen concentration in the blood. This process allows oxygen to move from the lungs into the bloodstream for transport to the body's cells.
oxyhemoglobin (hemoglobin bound to oxygen) is highest in the alveolar venule. This is the initial vessel carrying freshly-oxygenated blood away from the alveolus, which is the air-sac in the lung where gases are exchanged.
