Q

what are the functions of the lymphatic system?

A
  • absorbs excess interstitial fluid & return it to the bloodstream

Q

B lymphocytes

A
  • mature in bone marrow
  • 15-25% of lymphocytes
  • become plasma cells to produce antibodies
30
Q

what is the largest lymphatic organ? where is it located?

A

the spleen
*loc: LUQ of abdomen; below the diaphragm and lateral to the kidney

31
Q

what are the functions of the spleen?

A
  • phagocytose (consume) foreign material
  • phagocytose old RBCs and platelets
  • initiate an immune response
  • serve as a reservoir for RBCs and platelets
32
Q

the thymus is Greek for…

A

sweetbread

33
Q

how does immunity differ from the physical and cellular mechanisms?

A
  • specificity: directed against a specific pathogen
  • memory: can recognize a previous pathogen and is prepared to act against it
  • discrimination: learns to recognize “self” b/w “nonself” (foreign)
34
Q

what is immunity?

A

the ability to resist a specific infectious diseases

35
Q

cellular (cell-mediated) immunity

A

-a direct form of defense
- attack and destroy foreign and diseased cells

36
Q

humoral (anttibody-mediated) immunity

A
  • an indirect form of definition
  • employs antibodies produced by plasma cells (tag to destroy)

a normal cubic mm of blood contains _____ WBCs

A

5,000 to 10,000

45
Q

in leukocytosis, the total WBC count exceeds…

A

101,000 per cubic mm

46
Q

what conditions can increase the WBC count beyond its normal range?

A
  • allergic reactions (+ # of eosinophils)
  • typhoid fever, maleria, TB (+ # of monocytes)
  • bacterial infections (+ # of lymphocytes)
47
Q

leukemia

A
  • cancer of blood forming tissues
  • leukemic cells multiply and take over the bone marrow causing a deficiency in RBCs, WBCs, and platelets
48
Q

leokopenia

A

WBC count drops below 5,000 cells per cubic mm

49
Q

pancytopenia

A

noteably reduced RBCs, WBCs, and platelets.
