Components

Erythrocytes are the red blood cells with no nucleus that makes up the blood of all humans. Erythrocytes make up about 40-50% of the blood’s total volume. The protein molecule, hemoglobin, makes up about 95% of the red blood cells. Leukocytes are the white blood cells in the blood, there are very many types and the amount varies. In a normal human leukocytes make up around less than 1% of the volume of blood. Thrombocytes are the platelets that are responsible for clogging, ruptures and injuries in blood vessel walls. Plasma, the liquid part of blood or lymph, distinguished from the suspended elements. Around 55% of our blood’s volume is composed of plasma. Plasma is mainly composed of blood clotting factors, vitamins, minerals, hormones, enzymes, proteins, antibodies, sugars, and lipids. The erythrocytes, leukocytes, and thrombocytes are suspended in the plasma.
