Yes. Main buffer is HCO3-.
The pH of arterial blood plasma is 7.40.

The buffer system in whole blood is made up of carbonic acid-bicarbonate buffer system and protein buffer system. The carbonic acid-bicarbonate buffer system helps regulate pH by balancing the levels of carbonic acid and bicarbonate ions. The protein buffer system involves proteins like hemoglobin that can bind to and release hydrogen ions to help maintain a stable pH in the blood.
The buffer system in blood is formed by carbonic acid (H2CO3) and bicarbonate ions (HCO3-). This system helps maintain the pH of blood within a narrow range by absorbing or releasing hydrogen ions as needed.
Buffer systems help to maintain constant plasma pH. There are three buffer systems: Protein buffer system, phosphate buffer system and bicarbonate buffer system. Among these, the bicarbonate buffer system is the most predominant. Buffer Systems function as "shock absorbers" that accept excess H+ ions or OH- ions and keep blood pH constant. For example, if there is an increase in acidity of blood due to excess HCl (a strong acid), then NaHCO3 (Sodium bicarbonate) will buffer it to a weak acid (H2CO3). HCl+NaHCO3 = NaCl+H2CO3
Carbonic acid-bicarbonate buffer system Acids (H+) released into the blood by the body cells tend to lower the pH of the blood and cause it to be acidic. Alkali resists a rise in pH

HCO3 in the plasma acts as a buffer that helps regulate the pH of the blood by maintaining it in a narrow range. It helps to neutralize acids produced in the body and maintain the overall acid-base balance.
plasma proteins help stabilize blood volume, control bleeding, fight pathogens; concentrations of molecules dissolved in water as plasma control which substances diffuse into and out of the blood
The most important buffer for maintaining acid-base balance in the blood is the carbonic acid-bicarbonate buffer.
Blood contains blood plasma, if you cook the blood then the plasma is still in it. However cooking denatures (changes) the proteins in the plasma.
Three common buffer systems are the bicarbonate buffer system in blood, the phosphate buffer system in intracellular fluid, and the protein buffer system in plasma. These systems help maintain a stable pH in the body by absorbing or releasing hydrogen ions as needed.
