the _____ and _____ systems share some of the same structures and functions.
lymphatic; immune
both the lymphatic and immune systems contain _____ ____, ____, ____ ____, and some of the disease-fighting ____ ____.
lymph nodes; spleen, thymus gland; immune cells
the lymphatic system reduces ____ ____ by _____ fluid from capillary beds
tissue edema; removing
the lymphatic system returns the ____ from the fluids to the _____.
proteins; blood
the lymphatic system traps and filters ____ ____, such as cancer cells and microbes, with the help of cells called _____
cellular debris; macrophagesq
the lymphatic system recycles ____ ____ to various parts of the body.
body fluid
the lymphatic system circulates ____ to assist with the immune response.
lymphocytes
the lymphatic system moves fats from the ____ ____ to the blood.
GI tract
the immune system protects the body against ____ ____ invasion.
foreign body
the immune system coordinates activities in the _____ , ____ ____, and the ____ ____ to protect the body from foreign body invasion.
blood; body tissues; lymphatic system
the immune system fights off ______ and protects against future _____ by producing a variety of immune responses.
infections
the immune system produces _____ (immunoglobulins).
antibodies
the lymphatic system is similar to both the _____ and _____ systems in that it involves a network of vessels that transport fluid around the body.
cardiovascular and blood
once plasma leaves the vascular system it is known as ____ ____
interstitial fluid
____ ____ provides nutrients and performs other functions in the exchange of fluids and from the cells.
interstitial fluid
fluid that contains white blood cells and other substances and flows in the lymphatic vessels.
lymph
the ____ ____ are thin-walled vessels that receive fluid and debris from the bloodstream.
microscopic capillaries
specialized organs that filter harmful substances from the tissues and assists in the immune response.
lymph nodes
organ of the lymph system that filters and stores blood, removes old red blood cells and activates lymphocytes. Also filters foreign material from the blood, store blood, remove damaged or old red blood cells, and activate lymphocytes that destroy some of the foreign substances filtered from the blood.
spleen
a soft gland with two lobes that is involved in immune responses; located in mediastinum.
thymus gland
specialized white blood cells that receive markers in the thymus are responsible for cellular immunity and assist with hormonal immunity.
T cells
a kind of lymphocyte that manufactures antibodies.
B lymphocytes
hormone secreted by the thymus gland that aids indistrubution of thymocytes (T lymphocytes) and lymphocytes

the immune system relies on the ____ ____ (RES), ____ system, ____ ____ system (or phagocytic system), and lymphoid system play a significant role in the functions of the immune system.
reticuloendothelial system; hematopoietic; mononuclear phagocytic;
hematopoietic system is responsible for the production of the blood cells in the ____ ____.
bone marrow
the leukocytes include ____, monocytes, and granulocytes.
lymphocytes
The RES and phagocytic systems provide the phagocytes of the tissues and the phagocytes of the blood that are called ____ and ____.
macrophages; microphages
Phagocytes remove foreign particles from the body by the process of _____, the internalization or “eating” of the particles and the digestion of the particles for presentation to the appropriate cells of the immune system.
phagocytosis
the B cells are responsible for the production of _____ (also called immunoglobulins), that is, the humoral response.
antibodies
when disease-causing agents, _____, try to enter the body they often are stopped by the skin, the cilia in the nostrils, and various mucous membranes.
pathogens
in the bloodstream, certain substances called ____ may provoke an immune response to certain diseases.
antigens
____ ____ is the human body’s natural resistance to certain diseases.
natural immunity
