Oct 30, 2023 · Blood makes up about 8% of the human body weight. It contains erythrocytes, leucocytes, thrombocytes (platelets) and plasma. The volume percentage of all blood cells in the whole blood is about 45% of adults (hematocrit). The rest consists of liquid plasma (e.g. water, plasma proteins, electrolytes etc.). The blood is composed of:

Jan 17, 2023 · The cellular components of blood are erythrocytes (red blood cells, or RBCs), leukocytes (white blood cells, or WBCs), and thrombocytes (platelets). By volume, the RBCs constitute about 45% of whole blood, the plasma about 54.3%, and white blood cells about 0.7%. Platelets make up less than 1%. Although it consists of cells suspended in fluid ...
The platelets are responsible for blood clotting. Interstitial fluid that surrounds cells is separate from the blood, but in hemolymph, they are combined. In humans, cellular components make up approximately 45 percent of the blood and the liquid plasma 55 percent. Blood is 20 percent of a person’s extracellular fluid and eight percent of weight.

Recall that blood is a connective tissue. Like all connective tissues, it is made up of cellular elements and an extracellular matrix. 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).
Figure 1. The cells and cellular components of human blood are shown. Red blood cells deliver oxygen to the cells and remove carbon dioxide. White blood cells—including neutrophils, monocytes, lymphocytes, eosinophils, and basophils—are involved in the immune response. Platelets form clots that prevent blood loss after injury.

Jul 26, 2017 · Here we will discuss the most vital components of blood, including serum, white blood cells or “leukocytes,” red blood cells, and platelets. Plasma. Plasma is the liquid which carries the red blood cells, white blood cells, platelets, and other substances found in blood. More than half the volume of our blood is composed of this fluid.
