    Question

    What is the liquid constituent of blood known as?

    A.

    Serum

    B.

    Lymph

    C.

    Plasma

    D.

    Monocyte

    E.

    Leukocyte

    Correct option is C

    The correct answer is: (c) Plasma

    • The plasma is the liquid component of blood that makes up about 55% of blood's volume.

    • It is a yellowish fluid that consists of water, proteins (such as albumin, globulins, and fibrinogen), electrolytes, nutrients, hormones, and waste products.

    • Plasma serves to transport blood cells, nutrients, hormones, and waste products to and from the cells and organs.

    • Serum is similar to plasma but lacks clotting factors (like fibrinogen) and is obtained after blood has clotted.

    • Lymph is a fluid that circulates through the lymphatic system, separate from the blood circulation.

    • Monocytes and Leukocytes are types of white blood cells involved in the immune response, not the liquid component of blood.

    Information Booster:

    • Plasma is vital for maintaining blood pressure, circulating nutrients, and regulating body temperature.

    • Albumin, the most abundant protein in plasma, helps in maintaining osmotic pressure and preventing fluid loss from blood vessels.

    Additional Information:

    • Serum is the part of blood plasma that remains after the clotting process, so it lacks clotting factors.

    • Lymph contains white blood cells and is involved in immune function, while plasma is essential for nutrient transport, waste removal, and maintaining the pH balance of blood.
