Changes in blood flow represent the body's first response to injury. State true or false.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Blood flow changes are indeed the body's initial response to injury. When an injury occurs, the body's blood vessels constrict to minimize bleeding and redirect blood flow to the injured area. This response is known as vasoconstriction. Additionally, the body releases chemicals that cause blood vessels to dilate, increasing blood flow to the injured area. These changes in blood flow help deliver oxygen, nutrients, and immune cells to the site of injury, promoting the healing process. Therefore, the statement "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. When an injury occurs, the first response of arterioles is vasoconstriction, which means they narrow in diameter. This helps to reduce blood flow to the injured area, limiting bleeding and preventing further damage. Vasoconstriction also helps to decrease inflammation and promote healing. Therefore, vasoconstriction is the initial response of arterioles to injury.Rate this question:

What does the term opsonization mean?
- A.
To mark for destruction
- B.
To make optimal
- C.
To make foreign
- D.
To make attractive
Correct Answer
A. To mark for destructionExplanation
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:

State true or false- 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
PMNs, also known as polymorphonuclear leukocytes or neutrophils, are a type of white blood cell that plays a crucial role in the immune response against bacterial infections. When a PMN encounters a bacterium, it uses its pseudopods, which are flexible extensions of the cell membrane, to surround and engulf the bacterium. This process is called phagocytosis and allows the PMN to recognize the bacterium as foreign and initiate an immune response to eliminate it. Therefore, the statement "A PMN encounters and recognizes a bacterium as foreign by the pseudopods extending from the surface of the PMN" is true.Rate this question:
