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.

What nitrogenous organic molecule can function as a biological buffer in cells and tissues?
plasma
Which buffer pairs is considered the major plasma buffering system?
what pair is considered the major plasma buffering system
Plasma protein helps retain water in blood by maintaining what?
Plasma proteins not only maintain osmotic pressure, but also buffer the blood; a function they share with the salts, as we shall discuss in more detail later. Water provides fluid environment and proteins create osmotic pressure, aid clotting, and help buffer blood
What is a major function of the plasma proteins in the blood?
Buffering in the blood is by the carbonic acid - hydrogen carbonate buffer. (Hydrogen carbonate is also called by the older name "bicarbonate"). The plasma pH is maintained at about 7.4. Functions of blood proteins: serum albumin: binds to certain molecules to help transport them in the bloodstream; contributes to the osmotic pressure of the plasma to the extent of 80% serum globulins: are antibodies, contributes to the osmotic pressure of plasma to the extent of 20% serum fibrinogen:antibodies serum prothrombin: blood clotting factor
Blood consists of cells and a liquidWhat is the name of the liquid?
Blood consists of plasma, blood cells, and platelets
The buffer system in blood is formed by?
The buffer system that operates in blood plasma is the bicarbonate buffering system. The chemical equation for this system is the following CO2 + H2O <--> H2CO3 <--> HCO3- + H+.
Is blood plasma a good buffer?
Yes. Main buffer is HCO3-. The pH of arterial blood plasma is 7.40.
What is the most abundant buffer system in the Intracellular Fluid and blood plasma?
protein buffer
What nitrogenous organic molecule can function as a biological buffer in cells and tissues?
plasma
Which buffer pairs is considered the major plasma buffering system?
what pair is considered the major plasma buffering system
Is it true the phosphate buffer system is relatively unimportant for buffering blood plasma?
white blood cells
Compare the buffer system in the whole blood?
The blood contains buffers like bicarbonate and phosphate buffers. The bicarbonate buffer is by far, the most important.
How does the Blood buffer system work?
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
What is the major buffer system in human blood?
Buffer systems help to maintain constant plasma pH. There are three buffer systems - Protein buffer system, phoshate buffer system and bicarbonate buffer system.

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

What state of matter has strong forces between the particles?
The state of matter that holds its shape is called solid. Other states such as liquid, gas, and plasma, do not hold their shape.
