1Lymph from which of the following area of the body will pass through the thoracic duct before entering the bloodstream?

None of the choices are correct.
2A cell has engulfed a substance from the extracellular material and has migrated to a lymph node to interact with a helper T cell. Which of the following statements best describes this cell?
This is an antigen-presenting cell that interacts with the helper T cell through an MHC class II molecule.
This is a cytotoxic T cell that interacts with the helper T cell through an MHC class I molecule.
This is a cytotoxic T cell that interacts with the helper T cell through an MHC class II molecule.
This is an antigen-presenting cell that interacts with the helper T cell through an MHC class I molecule.
3Which of the following statements concerning immunity is correct?
All of the choices are correct.
Adaptive immunity demonstrates specificity, which means that lymphocytes only destroy viruses and ignore all other types of pathogens.
Adaptive immunity demonstrates memory, meaning each lymphocyte responds to a particular pathogen, but responds similarly with each infection.
Adaptive immunity responses to pathogens improves over time due to generation of memory, which includes an increase in the number of lymphocytes that respond faster than during the original infection.
4Which is the proper order of events in cell-mediated immunity?
(1) Cloning of cytotoxic T cells and memory T cells
(2) Antigen presented to T lymphocyte
(3) Activation of T lymphocytes
(4) Cytotoxic T cells attack target cells

Binds to mast cells and basophils and stimulates the inflammatory response
Activates complement and promotes phagocytosis; can cross the placenta and provide immune protection to the fetus and newborn; responsible for Rh reactions, such as hemolytic disease of the newborn.
Secreted into saliva, into tears, and onto mucous membranes to provide protection on body surfaces; found in colostrum and milk to provide immune protection to newborns
Activates complement and acts as an antigen-binding receptor on the surface of B cells; responsible for transfusion reactions in the ABO blood system; often the first antibody produced in response to an antigen
Functions as antigen-binding receptors on B cells

Artificial active
13 accurately describes the thymus gland?
The thymus gland decreases in size after age 60.
The thymus gland lacks a capsule.
The thymus gland contains many reticular fibers.
Lymphocytes are found only in the medulla of the thymus gland.

15A woman has her right breast and right axillary lymph nodes removed. Which of the following might occur?
Lymph drainage would be affected in her left arm.
Right lymphatic duct drainage decreases causing edema in the right arm.
The thoracic duct would be severed.
Cisterna chyli flow increases.
16The lymphatic system differs from the cardiovascular system in that
lymph capillaries allow free movement of fluid in and out of the capillaries.
lymph capillaries do not contain any fluid.
the lymphatic system only carries fluid away from tissues.
the lymphatic vessels have their own “pump” to assist flow.

Viral antigens are processed by the MHC class I mechanism and are presented to the cell surface.
Cytotoxic T cells bound to the MHC class I processed antigens release lymphokines.
