Lymphatic System UPDATED ACTUAL
Exam Questions and CORRECT Answers
Lymphatic Cells - CORRECT ANSWER - the cells of the lymph, which protects the body
against foreign invaders
Red Bone Marrow - CORRECT ANSWER - the part of the bone marrow that contains blood
stem cells that can turn into red blood cells, white blood cells, or platelets
Multipotent - CORRECT ANSWER - the ability to develop into any type of tissue
Immunocompetent - CORRECT ANSWER - the have a normal immune response to an
antigen
Thymus - CORRECT ANSWER - the gland that makes the white blood cells, called T
lymphocytes or T cells, which are an important part of the body's immune system
Antigen - CORRECT ANSWER - a substance or toxin that induces an immunological
response in the body
Lymphocytes - CORRECT ANSWER - a form of white blood cell occurring in the lymphatic
system
Macrophages - CORRECT ANSWER - a white blood cell that surrounds and kills invading
microorganisms and stimulates the action of other immune system cells
Immune Response - CORRECT ANSWER - the natural response of the body of recognizing
foreign invaders and defending itself against them
, Medulla - CORRECT ANSWER - the deep cavity of the lymph node that is made up of
lymphatic tissue cords
Medullary Sinuses - CORRECT ANSWER - the spaces that separate the medullary cords and
drain the lymph into the efferent lymphatic vessels
Histiocytes - CORRECT ANSWER - normal immune cells that play an important role in the
regulation of immune functions
Reticular Cells - CORRECT ANSWER - a type of fibroblast that provides structural support
to most lymphoid organs
Hilum - CORRECT ANSWER - the connection between the lungs and their supporting
structures and where pulmonary vessels enter and exit the lungs
Inner Paracortex - CORRECT ANSWER - the inner part of the cortex that has the dendritic
cells, which present antigens to T-cells and stimulate them toward clonal selection
Fibrous Capsule - CORRECT ANSWER - the collagenous structure that surrounds and
supports the lymph nodes
Afferent Lymphatic Ducts - CORRECT ANSWER - the structures that enter the lymph nodes
and contain valves to prevent backflow or lymph
Subscapular Sinus - CORRECT ANSWER - the space between the capsule and the cortex that
allows the transportation of the lymphatic fluid
Efferent Vessel - CORRECT ANSWER - the structures that leave the lymph node at the
hilum and contain valves that prevent lymph from flowing in the wrong direction
