caption: a diagram shows where carbon dioxide transport and chloride movement
exif: {"Image DocumentName": "Carbon Dioxide Transport and Chloride Movement", "Image ImageDescription": "(a) Tissue capillaries: as C O2 enters red blood cells, reacts with water to form bicarbonate and hydrogen ions. C hloride ions enter the RB C and bicarbonate ions leave: chloride shift. H ydrogen ions combine with hemoglobin. (pH of RBC does not decrease bec. hemoglobin is a buffer ) Lowering the concentration of bicarbonate and hydrogen ions inside red blood cells promotes the conversion of C O2 to bicarbonate ion. (b) Pulmonary capillaries: C O2 leaves red blood cells, resulting in the formation of additional C O2 from carbonic acid. The bicarbonate ions are exchanged for chloride ions, and the hydrogen ions are released from hemoglobin. Increased plasma carbon dioxide lowers blood p H. The respiratory system regulates blood p H by regulating plasma carbon dioxide levels.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
