n an untrained individual (and a trained individual, to some extent) high-intensity exercise, such as a 100-m sprint, can cause muscles to produce more lactic acid than can be cleared quickly from the tissue bed. This results in a short-term accumulation of lactic acid in the muscle that, in turn, creates local acidosis due to the release of hydrogen ions.

What effect do you expect the resulting acidosis has on local regulation of blood flow?

What is this type of response called?

Hi hi!

Respiratory acidosis is an acid-base balance disturbance due to alveolar hypoventilation. Alveolar hypoventilation leads to an increased PaCO2 (ie, hypercapnia). The increase in PaCO2, in turn, decreases the bicarbonate (HCO3–)/PaCO2 ratio, thereby decreasing the pH. Sooo, a better question would be, what effects does lower pH have on blood flow.

If, for instance, the pH of the blood and external fluid is too low (too many H+ ions), then an excess of H+ ions will enter the cell. Maintaining the proper pH is critical for the chemical reactions that occur in the body. In order to maintain the proper chemical composition inside the cells, the chemical composition of the fluids outside the cells must be kept relatively constant.
