11.1 Immune Response

11.1 Immune Response

1. Define immunity.

2. Describe types of immunity:

   Innate and Adaptive.

Multiple Choice

An agent that causes a disease is a:

• Pathogen

• Virus

• Antigen

• Leukocyte

Multiple Choice

An antigen is:

• a phagocytic cell

• used to combat infections.

• used to destroy antibodies.

• any molecule that is recognized as foreign by the immune system.

Multiple Select

What is the body's physical barrier defense against infection?

(more than one correct answer)

• Skin

• Mucous membrane

• Phagocytic cells

• Mucus and secretions

Multiple Choice

Lisa notices that shortly after cutting her arm accidentally the area around the cut is turning red and feeling hot. Which immune system defense is Lisa experiencing?

• inflammation

• white blood cell clotting

• flu

• fever

Multiple Choice

Which statement about the inflammatory response is false?

• Interferons and neutrophils secrete histamine.

• Increased blood flow to infected areas bring more phagocytic cells.

• Swelling results from an increase in the volume of interstitial fluid in the infected area.

• Trigger blood vessel dilation and increased capillary permeability.

Multiple Choice

Cells that engulf and digest pathogens are:

• plasma cells

• phagocytic cells

• helper T cells

• cytotoxic T cells

Multiple Choice

Natural killer cells destroy infected cells and cancer cells by:

• releasing antibiotics to break down the cell membrane.

• releasing cytokines, perforins, and granzymes to break down the cell membrane.

• releasing histamine to give signals other blood cells to aggregate.

• releasing lysozyme to digest target cells.

Which of the following are examples of innate (non-specific) immunity?

(more than one correct answer)

• Skin forms a physical and antiseptic barrier to pathogens.

• Leukocytes detect the antigens of the bacterium and produce antibodies.

• Macrophages engulf bacterial cells at the site of infection.

• The body produces large numbers of memory cells.
