Unit 11 Part 1

The vector for this disease is the mosquito.

• malaria

• cholera

• HIV

• smallpox

What does penicillin break down?

• Cellulose cross links

• Murein cross links

• Peptidoglycan cross links

• Chitin cross links

Identify cell 1.

• Red Blood Cell

• Lymphocyte

• Monocyte

• Neutrophil

Identify cell 2.

• Red Blood Cell

• Lymphocyte

• Monocyte

• Neutrophil

Identify cell 3.

• Red Blood Cell

• Lymphocyte

• Monocyte

• Neutrophil

What describes a function of a neutrophil?

• Found in tissues and secrete cytokines
• Leave the blood and accumulate at sites of inflammation
• Leave the blood and secrete cytotoxins when exposed to cells
• Circulate the blood and produce antigens against infection

Which statement about both B-cells and T-cells is correct?

• Become active only when a specific antibody binds to their surface receptor
• Divide to form clones when meeting an antitoxin in a cell
• Produce memory cells to respond to an antigen when exposed in the future
• Release hormone-like cytokines which stimulate the release of antibodies

B-lymphocytes and T-lymphocytes are often unable to respond to the antigens on pathogens that are intracellular parasites. What is the reason for this?

• Antigens are constantly mutating
• Antigens can destroy lymphocytes
• Lymphocytes do not encounter antigens
• Lymphocytes do not recognize antigens

What describes a non-specific immune response?

• Activation of killer-T cells by infected cells
• Cloning of B-lymphocytes to form plasma cells
• Ingestion of a bacterial cell by a neutrophil
• Presentation of antigens on the cell surface of macrophages

What are the function(s) of plasma cells during an immune response?

• 2 only

• 3 only

• 2 and 3 only

• 1, 2 and 3
