    Study Notes

    Blood Function and Composition

    • The main function of blood is to transport oxygen and nutrients to cells and remove waste products.
    • Plasma is the liquid component of blood, making up about 55% of its total volume.
    • The main component of plasma is water (about 92%), with the remaining 8% consisting of proteins, nutrients, hormones, gases, and waste products.

    Blood Cell Formation

    • The process of blood cell formation, also known as hematopoiesis, takes place in the bone marrow.

    Blood Cell Types

    • The most abundant type of blood cell is the red blood cell (also known as erythrocytes).

    Plasma Proteins

    • Plasma proteins are a crucial component of plasma, making up about 7% of its total composition.
    • The constituents of plasma proteins include albumin, globulins, and fibrinogen.
