Changes in blood flow represent the body's first response to injury.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
When the body is injured, one of the first responses is a change in blood flow. This change in blood flow is necessary to deliver oxygen, nutrients, and immune cells to the injured area to promote healing. Additionally, increased blood flow can also help remove waste products and toxins from the site of injury. Therefore, the statement that changes in blood flow represent the body's first response to injury is true.Rate this question:

What is the first response of arterioles to injury?
- A.
Vasoconstriction
- B.
Vasodilation
- C.
Redness
- D.
Edema
- E.
Hyperemia
Correct Answer
A. VasoconstrictionExplanation
Arterioles are small blood vessels that regulate blood flow to various tissues. When an injury occurs, the arterioles initially respond by constricting or narrowing their diameter, which is known as vasoconstriction. This response helps to reduce blood flow to the injured area, limiting bleeding and preventing further damage. Vasoconstriction also helps to minimize the swelling and inflammation that can occur after an injury. Therefore, vasoconstriction is the first response of arterioles to injury.Rate this question:

- A.
Cementing
- B.
Pavementing
- C.
Margination
- D.
Adhesion
Correct Answer
C. MarginationExplanation
The correct answer is "margination." Margination refers to the phenomenon where white blood cells (WBCs) marginate and become attached to the edge of the endothelium. It is an important step in the inflammatory response, where WBCs move from the center of blood vessels to the vessel walls in order to reach the site of infection or injury. "Pavementing" and "adhesion" are not the correct terms for this specific phenomenon. "Cementing" is not a recognized term in this context.Rate this question:

Margination of neutrophils is the first cellular change of inflammation.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
The statement is true because margination of neutrophils is indeed the first cellular change that occurs during inflammation. Margination refers to the process in which neutrophils adhere to the walls of blood vessels near the site of inflammation. This is followed by their migration through the vessel walls and into the inflamed tissue, where they play a crucial role in the immune response by engulfing and destroying pathogens. Therefore, margination of neutrophils is an essential initial step in the inflammatory process.Rate this question:

What does the term opsonization mean?
- A.
To make tasty
- B.
To make optimal
- C.
To make foreign
- D.
To make attractive
Correct Answer
A. To make tastyExplanation
Antibody opsonization is the process by which a pathogen is marked for ingestion and destruction by a phagocyte. Opsonization involves the binding of an opsonin, i.e., antibody, to a receptor on the pathogen's cell membrane. After opsonin binds to the membrane, phagocytes are attracted to the pathogen. The Fa and Fb portion of the antibody binds to the antigen, whereas the Fc portion of the antibody binds to an Fc receptor on the phagocyte, facilitating phagocytosis. The receptor-opsin complex can also create byproducts like C3b and C4b which are important components of the complement system. These components are deposited on the cell surface of the pathogen and aid in its destruction.Rate this question:

A PMN encounters and recognizes a bacterium as foreign by the pseudopods extending from the surface of the PMN.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Pseudopods are temporary extensions of the cell membrane that allow cells, such as PMNs (polymorphonuclear leukocytes), to move and engulf foreign particles, including bacteria. These extensions help the PMN to encounter and recognize the bacterium as foreign, triggering an immune response. Therefore, the statement that a PMN encounters and recognizes a bacterium as foreign by the pseudopods extending from its surface is true.Rate this question:
-

-
- 13.
Immunoglobulins (IgG-Fc) and complement (C3) both act as opsonins.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Both immunoglobulins (specifically IgG-Fc) and complement (specifically C3) are known to act as opsonins. Opsonins are molecules that enhance the process of phagocytosis, which is the engulfing and destruction of pathogens by immune cells. By binding to the surface of pathogens, opsonins facilitate the recognition and uptake of these pathogens by immune cells. Immunoglobulins, such as IgG-Fc, can bind to pathogens and mark them for phagocytosis. Complement proteins, particularly C3, can also bind to pathogens and enhance their recognition and uptake by immune cells. Therefore, both immunoglobulins and complement can function as opsonins.Rate this question:

The serous fluid is readily resorbed without consequences if the cause is eliminated.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Serous fluid is a clear, watery fluid that is produced by serous membranes in the body. It helps to lubricate and reduce friction between organs and tissues. When there is an excess of serous fluid, it can cause swelling or effusion in the affected area. However, if the underlying cause of the excess fluid is eliminated, such as by treating an infection or resolving inflammation, the serous fluid can be readily resorbed by the body without any negative consequences. Therefore, the statement that the serous fluid is readily resorbed without consequences if the cause is eliminated is true.Rate this question:
