Q.1
In lymph nodes
  • white blood cells mature into T cells.
  • lymph drains back into the circulatory system.
  • old and damaged red blood cells are destroyed.
  • B and T cells gather and attach to foreign antigens.
Q.2
Which of the following cells would NOT be found in a germinal center in a lymph node?
  • dendritic cells
  • B lymphocytes
  • plasma cells
  • monocytes
Q.3
A 5-year-old child falls and scratches herself and within a few days has an enlarged lymph node in the area draining the abrasion. The cells in the lymph node are reacting to the foreign stimulus that entered the skin and that was transported to the lymph node by which of the following?
  • immunoglobulin
  • T cells
  • Dendritic cells
  • TLRs
Q.4
Lymph nodes and spleen have germinal centers in which B cells respond to antigen and produce antibodies. A function unique to the spleen w.r.t. other peripheral lymphoid organs is
  • filtration of blood-borne pathogens.
  • production of dendritic cells.
  • production of red blood cells.
  • antigen presentation
Q.5
Virus replication may be slowed down by the natural production or administration of this signaling protein:
  • interferon
  • histamine
  • plasma cell
  • antibodies
Q.6
First-line defences that mammals have against invasion by disease-causing bacteria include
  • lysozymes.
  • interferons.
  • antibodies.
  • cytotoxic T cell.
Q.7
Works with T cells, a type of white blood cell that is key to the immune system’s ability to fight off infection and disease
  • Vitamin E
  • Vitamin C
  • Vitamin A
  • Vitamin D
Q.8
An organism that enters a life form and causes disease or sickness is a/an:
  • macrophage
  • pathogen
  • vaccine
  • flu
Q.9
All of the following are components of the lymphatic system EXCEPT:
  • yellow bone marrow
  • tonsils
  • spleen
  • nodes
Q.10
A type of cell that "digests" pathogens is known as a/an:
  • helper T cell
  • macrophage
  • suppressor T cell
  • plasma cell
Q.11
This gland, located anterior to the heart, but posterior to the sternum, is the lymphatic site where T cells are produced and mature:
  • tonsils
  • trachea
  • thymus
  • thalamus
Q.12
A type of T cell that destroys infected cells is a:
  • cytotoxic T cell
  • helper T cell
  • memory T cell
  • suppressor T cell
Q.13
The organism that is infected by a pathogen/antigen is known as the:
  • survivor
  • infectee
  • source
  • host

Signs of an inflammatory reaction include redness, swelling, heat, and itch.
  • TRUE
  • FALSE
Q.18
A small injected dose of a pathogen that stimulates the production of antibodies is:
  • histamine
  • interferon
  • pathogen
  • vaccine
