Lymphatic and Immune System Review

What does lymphocytosis indicate?

• Deficiency of lymphocytes in the blood.

• Disease of lymph glands (nodes).

• Abnormal condition of increase in lymphocytes.

• Inflammation of lymph glands (nodes).

What is lymphadenopathy?

• Inflammation of lymph glands (nodes).

• Disease of lymph glands (nodes).

• Removal of the spleen.

• Swelling of tissue due to accumulation of lymph fluid in intercellular spaces.

What does the term splenomegaly refer to?

• Removal of the spleen.

• Enlargement of the spleen.

• Absence of the spleen.

• A syndrome marked by splenomegaly.

What does interstitial fluid pertain to?

• Pertaining to poison.

• An exaggerated hypersensitivity reaction to foreign proteins.

• Pertaining to fluid that lies between body cells and eventually becomes lymph fluid.

• Formation of lymph.

What is the meaning of asplenia?

• Enlargement of the spleen.

• Disease of lymph glands (nodes).

• Absence of the spleen.

• Swelling of tissue due to accumulation of lymph fluid in intercellular spaces.

The major tissues and organs of this system include the white blood cells and spleen.

• Circulatory 

• Immune

• Endocrine

• Digestive

Rejection of a newly transplanted organ is caused by

• the immune system reacting to the presence of the organ

• antibiotics that stimulate the immune system to attack the organ

• inheritance of genetic disorders from infected individuals

• development of cancerous cells in the organ

Lymphatic capillaries are found throughout the body. Both the lymphatic and circulatory systems transport substances between the bloodstream and body tissues. These two systems are also involved in fighting infections. The arrows shown in the diagram that go from the blood capillaries to the interstitial fluid most likely represent the

• release of red blood cells, so that they can diffuse into body cells and fight bacteria

• movement of materials from the circulatory system that will eventually enter lymphatic capillaries

• transport of digestive enzymes from the blood to help with the digestion of glucose in muscle cells

• transport of glucose molecules from the blood to be used by cells to attack proteins and fats

Doctors often use certain medications to treat infections. A few people have a reaction to some of these medications, such as itching, swelling, or trouble breathing. This is an example of

• using antibodies to cure a medical problem

• the body’s immune system overreacting to a usually harmless substance

• the body creating a mutation to fight unknown pathogens

• a vaccine causing the body to produce antigens against the infection

Doctors sometimes use a vaccine to prepare the body to defend itself against future infections. These vaccines most often contain

• antibodies

• antibiotics

• white blood cells

• weakened pathogens
