Gas exchange of co2
WebJan 17, 2024 · This is due to deoxygenated blood’s increased capacity to carry carbon dioxide, and from the carbon dioxide loaded from the tissues during tissue gas exchange. Bicarbonate Ions The majority (85%) of carbon dioxide travels in the blood stream as bicarbonate ions. The reaction that describes the formation of bicarbonate ions in the … WebGas Exchange across the Alveoli In the body, oxygen is used by cells of the body’s tissues and carbon dioxide is produced as a waste product. The ratio of carbon dioxide production to oxygen consumption is the respiratory quotient (RQ). RQ varies between 0.7 and 1.0. If just glucose were used to fuel the body, the RQ would equal one.
