What is the normal PO2 and PCO2 in mixed venous blood returning to the lungs?
Asked in Arteries
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.
How do you find the dissolved O2 content give plasma PO2 and Hb content?
PO2 can be estimate of dissolve O2,PO2 keep the oxygen on hemoglobin so if there is increase affinity of oxygen then required PO2 willbe low.each HB carry 20vol% O2 per 100ml of blood in a 100% saturation.if the dissolve oxygen become less then PO2 also become less in order to deliver more dissolve form to tissues.actua;;u ddissolve O2 at 100mmhg of PO2 is 0.3vol%/100ml of blood
What is po2?
PO2 IS THE OYGEN BLOOD LEVEL IN YOUR BODY (More specifically, pO2 is the partial pressure of oxygen in different parts of your body. For example, the partial pressure of oxygen (pO2) is higher in your lungs than it is in various tissues like muscles. Therefore, oxygen is absorbed in the lungs and dispersed through your muscles.)
Asked in Respiratory System
How gas exchanges across the respiratory membrane?
blood entering the lungs has a partial pressure of oxygen (PO2) of 40 mmHg and a partial pressure of carbon dioxide (PCO2) of 46 mmHg; alveoli, on the other hand, have a PO2 of 105 mmHg and a PCO2 of 40 mmHg. As the blood moves past the alveoli, oxygen and carbon dioxide will diffuse down their respective partial pressure gradients. Oxygen will move from the alveolar space (PO2 of 105 mmHg) to the blood stream (PO2 of 40 mmHg). Carbon dioxide will move from the blood (PCO2 of 46 mmHg) to the alveolar space (PCO2 of 40 mmHg). As the blood leaves the alveolus, the PO2 and PCO2 will have essentially equilibrated with the alveolar air.

Asked in Blood Pressure
How would the partial pressures of O2 and CO2 change in an exercising muscle?
Although venous levels change, arterial Pco2 and Po2 levels remain surprisingly constant during exercise. In fact, Pco2 may even decline to below normal and Po2 may rise slightly because of the efficiency of the respiratory adjustments. Increased blood flow does not cause a change in gas pressures. the only way to change gas pressures is by altering atmospheric pressure, ie. scuba diving, or changing elevation. Partial pressure of any blood born gas is always directly proportional to atmospheric pressure as evidenced by Dalton's law of partial pressures. However in exercising muscle metabolic processes temporarily increase Pco2 and decrease Po2 until equalized by sufficiently oxygenated arterial blood. So the short answer to your question is that intramuscular Pco2 pressures would increase and Po2 would decrease, but the partial pressures in the blood would remain constant.
