Understanding Inflammation Processes

What are the main stages of inflammation?

• The main stages of inflammation are vascular response, cellular response, and resolution.

• Cellular activation, tissue damage, and healing

• Vascular constriction, immune response, and recovery

• Vascular dilation, tissue repair, and infection

Describe the role of vasodilation in inflammation.

• Vasodilation has no effect on blood flow or inflammation processes.

• Vasodilation increases blood flow and permeability, aiding immune response during inflammation.

• Vasodilation constricts blood vessels, leading to decreased permeability in tissues.

• Vasodilation decreases blood flow and reduces immune response during inflammation.

What are the primary chemical mediators involved in inflammation?

• Adrenaline

• Serotonin

• Histamines, prostaglandins, leukotrienes, cytokines, chemokines

• Insulin

How do histamines contribute to the inflammatory response?

• Histamines decrease blood vessel permeability and restrict immune cell access to tissues.

• Histamines have no role in the inflammatory response and do not affect blood vessels.

• Histamines contribute to the inflammatory response by increasing blood vessel permeability and facilitating immune cell access to tissues.

• Histamines only cause allergic reactions and do not contribute to inflammation.

Identify the key inflammatory cells involved in acute inflammation.

• Fibroblasts

• Eosinophils

• Neutrophils, macrophages, mast cells

• B lymphocytes

What is the difference between neutrophils and macrophages?

• Neutrophils are short-lived cells that respond quickly to infections, while macrophages are longer-lived cells that clean up debris and activate the immune response.

• Neutrophils are the primary cells that clean up debris, while macrophages respond quickly to infections.

• Macrophages are short-lived cells that activate the immune response, while neutrophils are longer-lived cells that clean up debris.

• Neutrophils and macrophages are both long-lived cells that respond to infections.

Explain the role of cytokines in inflammation.

• Cytokines are primarily responsible for producing antibodies during inflammation.

• Cytokines have no significant role in the inflammatory process.

• Cytokines play a crucial role in mediating and regulating inflammation by facilitating cell communication, recruiting immune cells, and orchestrating the inflammatory response.

• Cytokines inhibit the recruitment of immune cells to the site of inflammation.

What are the characteristics of acute inflammation?

• Dryness, coldness, and numbness.

• Redness, heat, swelling, pain, and loss of function.

• Increased appetite, weight gain, and energy.

• Nausea, fatigue, fever, and chills.

How does chronic inflammation differ from acute inflammation?

• Chronic inflammation is always a short-term response.

• Chronic inflammation is long-lasting and can cause tissue damage, while acute inflammation is a short-term response aimed at healing.

• Acute inflammation causes long-term tissue damage.

• Chronic inflammation is a type of acute inflammation.

What are some common causes of chronic inflammation?

• Persistent infections, autoimmune diseases, exposure to irritants, obesity, and chronic stress.

• Genetic mutations

• Acute infections

• Seasonal allergies
