The phenomenon involving the greater combination of CO2 with hemoglobin at a lower Po2 and at a lower degree of hemoglobin saturation with O2 is called the?
Haldane effect
Low pH alters hemoglobin structure so that oxygen binds less strongly to hemoglobin at low PO2 This increases the effectiveness of?
internal respiration
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 happens to an oxygen gas when it reaches an alveolus?
It defuses throught the respiratory membrane and binds to hemoglobin (in humans) following a hemoglobin type-specific binding affinity curve (depending on the Po2 of the local atmosphere.)
The phenomenon involving the greater combination fo CO2 with hemoglobin at a lower PO2 and at a lower degree of hemoglobin saturation with O2 is called the?
Bohr effect. Incorrect. It is not the Bohr effect...it is actually the "Haldane effect"=The lower the PO2 and the lower the extent of hemoglobin saturation with oxygen (O2), the more CO2 can be carried in the blood. This phenomenon is called the Haldane effect. As per the Human Anatomy and Physiology eighth edition text book published 2010.
What are the factors that affect hemoglobin's affinity for oxygen?
The primary factor that determines how much oxygen is actually bound to hemoglobin is the partial pressure of oxygen (pO2) in the hemoglobin solution.
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.
Why does hemoglobin accept oxygen molecules in the lungs but give up oxygen molecules in tissue?
In the lungs where the oxygen concentration is high the binding of oxygen tohemoglobin is high. In respiring tissue where the oxygen levels are low and the CO2 levels are high the affinity of hemoglobin for oxygen is reduced and so the oxygen comes off the hemoglobin and is used by the cells. The driving force for this is the Bohr Effect whereby CO2 produced by the respiring cells dissolves in the blood as follows CO2 + CO2 --> H2CO3 --> H+ + HCO3-. The H+ produced bind to the hemoglobin and in doing so displace the oxygen
What is the name for PO2?
PO2(OH)2 is the same as H2PO4^- (note the negative charge). It would be dihydrogen phosphate.
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
