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 is the name for PO2?

PO2(OH)2 is the same as H2PO4^- (note the negative charge). It would be dihydrogen phosphate.


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.


The relative PO2 and PCO2 in pulmonary arteries and veins and systemic arteries and veins?

In pulmonary arteries, PO2 is around 40 mmHg and PCO2 is around 46 mmHg. In pulmonary veins, PO2 is around 100 mmHg and PCO2 is around 40 mmHg. In systemic arteries, PO2 is around 100 mmHg and PCO2 is around 40 mmHg. In systemic veins, PO2 is around 40 mmHg and PCO2 is around 46 mmHg.


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 would be the pH of a solution when H3PO4 equals H2PO4?

When H3PO4 equals H2PO4-, the solution is a buffer system. The pH of the solution would be around the pKa of the H3PO4/H2PO4- buffer system, which is around 7.2-7.4 for the first dissociation of phosphoric acid.


What is the chemical formula for PO2?

The chemical formula for dioxygen diphosphorus, which is commonly written as PO2, is P2O4.

How do you find the dissolved O2 content give plasma PO2 and Hb content?

To find the dissolved oxygen content in blood, you can use the oxygen content equation: Dissolved O2 = (0.0031 x PO2) + (1.36 x Hb). First, convert the plasma PO2 to mmHg if needed and ensure all values are in the correct units. Then, plug the values into the equation to calculate the dissolved oxygen content.


Is it reasonable that Brianna's arterial PO2 is the same as Christopher's?

It is not reasonable for Brianna's arterial PO2 to be the same as Christopher's unless they have the same physiological conditions and are breathing the same air. Arterial PO2 levels can vary depending on factors like altitude, lung function, and overall health.
