2 level in the blood rises the excess co 2 reacts

This preview shows page 1 - 2 out of 2 pages.

2 level in the blood rises the excess CO 2 reacts with water to form more carbonic acid, lowering blood pH. Increasing the rate and/or depth of respiration allows you to exhale more CO 2 . The loss of CO 2 from the body reduces blood levels of carbonic acid and there for adjusts the pH upward, toward normal levels. The body regulates the respiratory rate by the use of chemoreceptors, which primarily use CO 2 as a signal. The renal regulation of the body’s acid- base balance addresses the metabolic component of the buffering system. A decrease of blood bicarbonate can result from the inhibition of carbonic anhydrase by certain diuretics or from excessive bicarbonate loss due to diarrhea. Blood bicarbonate levels are also typically lower in people who have Addison’s disease in which aldosterone levels are reduced, and in people who have renal damage, such as chronic nephritis ( Key Concepts) . “Key Concepts:” PH Buffers in the Blood , .

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
