    Study Notes

    Functions of Blood Tissue

    • The main function of blood tissue is to transport oxygen and nutrients to cells and remove waste products.

    Composition of Blood Tissue

    • The plasma in blood tissue mainly consists of water and plasma proteins.
    • Plasma proteins mainly consist of albumins and globulins.
    • The plasma represents approximately 55% of the total blood volume.
    • The formed elements (red blood cells, white blood cells, and platelets) represent approximately 45% of the total blood volume.

    Plasma Components

    • Apart from water and plasma proteins, the plasma contains nutrients, hormones, gases, waste products, and electrolytes.
    • Fibrinogen, a protein involved in blood clotting, is also present in the plasma.

    Functions of Plasma Proteins

    • The main function of plasma proteins is to regulate blood viscosity and maintain blood pressure.
    • Albumins and globulins contribute to the viscosity of blood.

    Functions of Blood Cells

    • The main function of red blood cells (RBCs) is to carry oxygen from lungs to tissues.
    • RBCs are highly differentiated, biconcave disc-shaped cells that lack a nucleus and organelles.
    • The main function of platelets is to participate in blood clotting.
    • Leucocytes exert their functions in the tissues, where they help fight infections.

    Other Key Facts

    • Serum contains all the components of plasma except fibrin and proteins involved in coagulation.
    • The main constituent of Red Blood Cells' cytoplasm is hemoglobin.
    • A hemogram consists of counting the number of red blood cells, white blood cells, and platelets in a sample of blood.
    • The normal range for white blood cells count per mm3 of blood is 4,500-11,000.
