QUIZ

question 1/5

What is innate immunity?

Natural barriers (First line of defense) and inflammation (Second line of defense)

The response is very specific toward target

Third line of defence

QUIZ

RIGHT!

Explanation:Barriers are the first line of defense against infection and tissue injury. It is broadly specific. The inflammatory response is the second line of defense and occurs as a response to tissue injury or infection, which is also nonspecific.

QUIZ

question 2/5

What cells are involved with innate barriers?

Mast cells, granulocytes (neutrophils, eosinophils, basophils), monocytes/macrophages, natural killer cells, platelets, endothelial cells

Epithelial Cells

T-lymphocytes,,B lympocytes

QUIZ

RIGHT!

Explanation:

T-lymphocytes and B lymphocytes are part of adaptive immunity. Mast cells, granulocytes (neutrophils, eosinophils, basophils), monocytes/macrophages, natural killer cells, platelets, and endothelial cells are a part of the inflammatory response.

QUIZ

QUESTION 3/5

When pathogen invasion or tissue damage occurs, inflammation is initiated by guardian cells. What are the guardian cells?

Mast cells macrophages, and dendritic cells

Somatic cell

T cells and B cells

QUIZ

RIGHT!

Explanation: Mast cells, macrophages, and dendritic cells are guardian cells

QUIZ

QUESTION 4/5

Which pathway activates the complement system?

Classical pathway, alternative pathway, and lectin pathway

Antigen body

Intrinsic pathway

QUIZ

RIGHT!

Explanation: Antibodies activate the classical pathway. The alternative pathway is activated directly by substances found on the surface of infectious microorganisms. Alternative pathways are independent of antibodies and are activated by several plasma proteins.

QUIZ

QUESTION 5/5

Which function of the clotting system are exhibited at the site of injury or inflammation?

Prevents the spread of infection to adjacent tissues

Prevents clot formation at the site of injury

Vasodilation

QUIZ

RIGHT!

Explanation:Other functions include stopping bleeding, helping prevent the spread of inflammation and infection, keeping the invader near the site of injury, maximizing the access of inflammatory cells and proteins, initiating the formation of two fibrinopeptide's that are released during the formation of fibrin and are chemotactic for neutrophils and increased vascular permeability and provide a framework for repair and healing.

CLICK ONLY ON THE CORRECT STATEMENT 1/3

Example of physical and mechanical barriers: Epithelial cells of the upper respiratory tract can trap microorganisms through the production of mucus and remove them through the action of hair-like cilia.

The innate immune response is slow

You can drag the light to search through the darkness

The complement system is redness, heat, swelling, and pain

Mucus perspiration saliva tears and earwax are all examples of mechanical barriers

CLICK ONLY ON THE CORRECT STATEMENT 2/3

Snake bites, bee venoms, and toxins may cause activation.

Which statement regarding mast cells is true?

Mast cells are not involved in allergic reactions.

RIGHT!

Histamine causes vasoconstriction

Mast cells are found only in blood vessels.

CLICK ONLY ON THE CORRECT STATEMENT 3/3

Scavenger receptors

Complement receptors

Which receptor is expressed on macrophages and facilitates recognition and phagocytosis of bacterial pathogens?

RIGHT!

Pattern recognition receptors

Toll-like receptors

CLICK ONLY ON THE CORRECT STATEMENT 3/3

Neutrophils are the predominant phagocytes of early inflammation.

Neutrophils are the largest blood cells

Which statement is true regarding neutrophils?

RIGHT!

Neutrophils enter the site of injury after lymphocytes and macrophages.

Neutrophils are agranular

ERROR!

Wrong! That statement is incorrect
