Question

State the functions of the following in blood.
(i) Fibrinogen
(ii) Globulin
(iii) Neutrophils
(iv) Lymphocytes

Answer 1

(i) Fibrinogens are inactive blood plasma components. It is a plasma protein that is generated in the liver and transformed into fibrin during the development of blood clots.

Function

1. They form a clot or coagulum (a network of threads termed fibrin) under the action of the enzyme thrombin, in which dead and damaged parts of blood are trapped.

(ii) Globulins refer to a class of simple proteins (including myosin) that are insoluble in pure water but soluble in dilute salt solutions.

Function

1. Globulins are principally engaged in immunity or the body's defense system. and are essential for liver function, blood coagulation, and infection resistance. Globulins are classified into four categories.

(iii) Neutrophils are phagocytic cells that consume foreign organisms that enter the body.

Function

1. When pathogens enter the body, such as bacteria or viruses, neutrophils are among the first immune cells to respond. They go to the site of infection, where they consume the germs and release enzymes that kill them. Neutrophils also stimulate the activity of other immune cells.

(iv) Lymphocytes are specialized cells that are in charge of the body's immunological reactions.

Function

1. B and T lymphocytes are the two primary kinds of lymphocytes engaged in this process of immunity defense.
