Week 5 - Innate Immune Responses

This type of immunity can be called nonspecific and refers to the bodies defenses that are present since birth.

• resistance

• adaptive immunity

• acquired immunity

• innate immunity

This type of immunity is acquired during one's lifetime. It is induced by antigens that invade the body.

• innate immunity

• adaptive immunity

• nonspecific immunity

• normal microbiota

A part of the innate immunity. The bodies defensive response caused by microbial infection, physical damage or chemical agents.

• phagocytosis

• edema

• cytotoxicity

• Inflammation

Which type of immunity is found in plants, invertebrates, and vertebrates?

• innate (nonspecific)
• adaptive (specific)

Which line of defense includes the skin, sweat, mucous membranes, and normal microbiota?

• First
• Second
• Third

A phagocyte has what capability:

• Detect specific antigens

• Produce antibodies

• Engulf any materials considered 'non-self'

• Produce mucous

Which of the following is found on the surface of pathogens causing an immune response

• Antibody

• Antigen-binding site

• Prostaglandin

• Antigen

Which of the following is physical barrier of plants?

• Bark or thorns

• Ability to close and open stomata

• Waxy Cuticle

• All of the above

Antihistamines

• Increase inflammation

• Decrease Inflammation

• Do not effect Inflammation

• None of the above

Identify one difference between the first and second lines of defence.

• The first line aims to prevent infection while the second line responds to an infection

• The first line is made up of general responses while the second line is made up of barriers

• The first line includes white blood cells while the second line does not

• The first line is only activated if pathogens make it past the second line
