This is called the Bohr effect where a increase in pC02 which decrease the pH leads to a decreased affinity of hemoglobin to oxygen. This means that hemoglobin unloads oxygen in areas where pC02 is high e.g. active tissue and that the binding coefficient of hemoglobin is highest in the lung where pC02 is negligible.

Why is there a higher pco2 with rebreathing?

Rebreathing can lead to a higher PCO2 because it involves inhaling the already exhaled air, which contains higher levels of carbon dioxide. This reduces the exchange of fresh oxygen from the environment, causing an accumulation of carbon dioxide in the respiratory system and increased PCO2 levels.


Exchange of gases in the lungs?

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.


What effect does lack of oxygen have on active transport?

Lack of oxygen impairs aerobic metabolism, which is needed to produce the ATP required for active transport processes. This can lead to a decrease in the efficiency and effectiveness of active transport mechanisms, ultimately affecting the ability of cells to maintain ion gradients and transport molecules across membranes.

No, it is higher or the CO2 would not move out of the lungs.

Does pco2 decrease when bronchioles and systemic arterioles constrict?

Yes, pCO2 can decrease when bronchioles and systemic arterioles constrict. Bronchoconstriction reduces airflow and may limit CO2 exchange in the lungs, while systemic arteriolar constriction can decrease blood flow to tissues, leading to reduced CO2 production. However, the overall effect on pCO2 depends on the balance between ventilation and perfusion, as well as the metabolic activity of tissues. If ventilation is sufficiently impaired, pCO2 may actually increase despite systemic arteriolar constriction.


What are the PO2 and PCO2 in alveoli?

In the alveoli, the partial pressure of oxygen (PO2) is typically around 100 mmHg, while the partial pressure of carbon dioxide (PCO2) is approximately 40 mmHg. These values can vary slightly depending on factors such as altitude and individual respiratory conditions. The difference in these pressures facilitates the diffusion of oxygen into the blood and carbon dioxide out of the blood during gas exchange.
