Is the pO2 of blood in the pulmonary arteries is greater in the alveoli?

No, firstly pO2 is not a particularly good term for the measurement of oxygen within the blood as most of it is tied up in the heamoglobin molecules and as such is not part od the pO2. Secondly the pulmonary artery is the artery that carried deoxygenated blood from the heart to the lungs where they gain oxygen from the alveolar cavity. Under the laws of diffusion this means the pO2 in the alveoli must be higher than the "pO2" in the blood here, but even just common sense tells you that the oxygen levels in the blood here are very low as this is the whole point in the blood going to the lung.

What is the artery that takes blood to the alveoli?
The pulmonary artery takes the blood to the alveoli.
What type of blood is in the pulmonary arteries?
Deoxygenated. The blood is carried by the pulmonary arteries from the heart to the lungs to replenish the oxygen.
Which structure(s) carry oxygen-rich blood away from the heart?
The right ventricle pumps O2 poor blood into the lungs. The ventricular pressure has to be greater than that of the pulmonary artery to open the pulmonary valve and push the blood to the lungs.
What is true about pulmonary artery?
Pulmonary arteries are the only arteries that carry unoxygenated blood.
What is the function pulmonary arteries?
The pulmonary arteries deliver blood to the lungs from the heart so it can be oxygenated.
What is the artery that takes blood to the alveoli?
The pulmonary artery takes the blood to the alveoli.
Which organ receives blood from the pulmonary arteries?
The pulmonary arteries carry deoxygenated blood to the lungs.
What vessels take blood to and from the lungs?
The Pulmonary Artery
Difference of pulmonary arteries to ordinary arteries?
All arteries carry oxygenated blood except pulmonary artery. Pulmonary arteries carry deoxygenated blood to the lungs where it becomes oxygenated.
What is different about pulmonary arteries and pulmonary veins?
The pulmonary artery and pulmonary vein originates in the heart. What is different about them is that the pulmonary artery carries deoxygenated blood (blood without oxygen) as supposed to other arteries, which carry oxygenated blood. And the pulmonary vein carries oxygenated blood unlike other veins, which carry deoxygenated blood.
What type of blood is in the pulmonary arteries?
Deoxygenated. The blood is carried by the pulmonary arteries from the heart to the lungs to replenish the oxygen.
Is Pco2 is greater in the alveoli than it is in the arterial end of pulmonary capillaries?
No. Once blood reaches the alveoli it will immediately start to release CO2 to the air in our lungs and absorb O2 from the air in our lungs. This means that the PCO2 will be higher in the blood of the pulmonary artery than in the blood of the alveolus. If this were not so, then passing blood through the alveoli would be pointless.
Which structure(s) carry oxygen-rich blood away from the heart?
The right ventricle pumps O2 poor blood into the lungs. The ventricular pressure has to be greater than that of the pulmonary artery to open the pulmonary valve and push the blood to the lungs.
What is true about pulmonary artery?
Pulmonary arteries are the only arteries that carry unoxygenated blood.
Is o2 concentration greater in the pulmonary capillaries or alveoli?
In the alveoli
Blood vessel carrying oxygen rich blood?
Arteries (except the pulmonary artery) and one vein the pulmonary vein.
Why are the pulmonary arteries and umbilical arteries called arteries instead of blood vessels?
Pulmonary arteries and pulmonary veins are two different items. The pulmonary artery takes deoxygenated blood from the heart and into the lungs so that the blood can be oxygenated. The oxygenated blood then returns to the heart, via the pulmonary veins, in order to be pumped into the system circulation.
