What is the composition of blood plasma?

Whole blood minus erythrocytes (RBCs), leukocytes (WBCs), and thrombocytes (platelets) make up the plasma. Serum, sometimes mistakenly considered synonymous with plasma, consists of plasma without fibrinogen. Plasma contains 91% to 92% of water and 8% to 9% of solids.

Which formed elements erythrocytes leukocytes or platelets?

The cellular elements—referred to as the formed elements—include erythrocytes (aka red blood cells or RBCs), leukocytes (aka white blood cells or WBCs), and cell fragments called platelets (aka thrombocytes). The extracellular matrix, called plasma, makes blood unique among connective tissues because it is fluid.

What is the composition of the blood?

It has four main components: plasma, red blood cells, white blood cells, and platelets. Blood has many different functions, including: transporting oxygen and nutrients to the lungs and tissues. forming blood clots to prevent excess blood loss.

Which formed elements function in blood clotting?

The main job of platelets, or thrombocytes, is blood clotting. Platelets are much smaller in size than the other blood cells. They group together to form clumps, or a plug, in the hole of a vessel to stop bleeding.

Why is it called blood plasma?

The word “plasma,” derived from the ancient Greek “to mold,” had been in use in medicine and biology for some decades when American chemist and physicist Irving Langmuir (1881-1957) began experimenting on electrical discharges in gas at the General Electric Research and Development Center in upstate New York.

Which leukocyte is the smallest in size?

So our answer is Monocytes are the largest type of leukocytes while lymphocytes are smallest in size.

Why is my plasma pink?

The colour comes from the fuel, which is basically hydrogen . So the colour of a pure plasma is pink, if there is too much beryllium from the walls, that adds a blue green tinge, Oxygen is blue (that’s a bad sign, means there’s a leak) etc etc.

How much of the blood is platelets?

Whole blood contains red cells, white cells, and platelets (~45% of volume) suspended in blood plasma (~55% of volume).

Which is largest leukocyte?


  • Monocytes are the largest type of leukocyte and share phagocytosis duties with neutrophils.
  • They are slower to respond than neutrophils but are longer lasting, as they can renew their lysosomes for continued digestion.
