Which anion is the second most abundant in the extracellular fluid, next to Chloride?
Which anion is the second most abundant in the extracellular fluid, next to Chloride?
- Phosphate (PO4^3-)
- Lactate (L-)
- Bicarbonate (HCO3-) (correct)
- Sulfate (SO4^2-)
What is the process called when Chloride (Cl-) replaces Bicarbonate (HCO3-) in the RBC?
What is the process called when Chloride (Cl-) replaces Bicarbonate (HCO3-) in the RBC?
- Oxygen Dissociation
- Hemoglobin Exchange
- Chloride Shift (correct)
- Bicarbonate Swap
What happens to O2 when it reaches the lungs?
What happens to O2 when it reaches the lungs?
- It binds with Hemoglobin (HHb) in the RBC
- It dissociates from Hemoglobin (HHb) in the RBC
- It combines with H+ in the RBC
- It is released outside the RBC to be used by the tissues (correct)

Study Notes
Extracellular Fluid Composition
- Bicarbonate (HCO3-) is the second most abundant anion in the extracellular fluid, next to Chloride (Cl-).
Chloride Shift
- Chloride (Cl-) replaces Bicarbonate (HCO3-) in the Red Blood Cell (RBC) through a process called the Chloride Shift.
Oxygen Transportation
- When Oxygen (O2) reaches the lungs, it binds to Hemoglobin (Hb) in the Red Blood Cell (RBC).
Hemoglobin and Hydrogen Ions
- Hydrogen ions (H+) bind to Hemoglobin (Hb) in the Red Blood Cell (RBC) when the blood pH drops, forming Hemoglobin-H (HHb).
Total CO2 Composition
- In a healthy patient with a normal blood pH (7.35-7.45), Bicarbonate (HCO3-) is the main component of total CO2 (tCO2).
