Arterial po2 will not change because it's almost at maximum already. Venous po2 will decrease due to increased oxygen consumption by respiring muscle. Venous and arterial pCo2 will actually either stay the same or fall due to the increased ventilation stimulated by the increased Co2 production by respiring muscles. The increased pCO2 is detected by central and peripheral chemoreceptors and leads to increased ventilation, resulting in increased ventilation - causing pCo2 to remain normal or decrease. This mechanism cannot be used to explain the ventilation increase in light exercise because pCo2 hardly rises at all during light exercise, therefore the chemoreceptors may not be responsible for the mechanism resulting in increased ventilation,

What would be the pH of a solution when H3PO4 equals H2PO4?
Assuming the Ka= [H+][PO2-]/[PO3-] and that PO3=PO2- then we can safely assume Ka= [H+][PO2-]/[PO2-] and so Ka= [H+][PO2-]/[PO2-] Ka=[H+] since the Ka of Phosphoric acid is equal to 7.5x10-3 then we can take -log(7.5x10-3) to find the pH=2.12
Which blood vessel has a Po2 of 104 mm Hg?
Rather than a blood vessel with a value of 104mm Hg for Po2, it is alveolar gas thatt has a Po2 of 104 mm Hg
What is PO2 in blood?
PO2 in blood is the amount of gases in your blood. In medical terms, this is commonly called the Alveolar-arterial.
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.
What is the name for PO2?
PO2(OH)2 is the same as H2PO4^- (note the negative charge). It would be dihydrogen phosphate.
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
The relative PO2 and PCO2 in pulmonary arteries and veins and systemic arteries and veins?
Pulmonary artery/Systemic veins PCO2 = 45 PO2 = 40 Pulmonary vein/Systemic arteries PCO2 = 40 PO2 = 100
What is Po2 gas?
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.)
Where would highest PO2 occur?
aorta
What is normal arterial po2?
80-100
What is the difference between PO2 and Sp02?
there is not a difference
Why do peripheral chemoreceptors only detect a drop in PO2 below 60 mmHg?
Because they are less sensitive to small decreases in arterial Po2 level.
