1

These 3 systems are all linked

- hematological
- lymphatic
- immune

2

These are also a part of the hematopoietic system

lymph nodes

3

hematopoietic =

blood forming

4

All lymphoid organs link these systems

- hematologic
- immune

5

How do lymphoid organs link the hematologic and immune systems?

They are sites or residence, proliferation, differentiation, or function of
- lymphocytes
- mononuclear phagocytes

6

Disruption of hematologic system results in circulatory disorder and are characterized by:

- edema
- congestion
- infarction
- thrombus
- lymphedema
- lymphadenopathy
- splenomegaly

7

edema =

excess fluid in interstitial tissues or body cavities

8

congestion =

excess blood within vessels of an organ or tissue

9

infarction =

area of necrosis

10

thrombus =

solid mass of clotted blood

11

lymphedema is this type of disorder

hematolymphatic

12

lymphedema =

obstruction of lymph vessels or nodes

13

lymphadenopathy =

abnormal enlargement of lymph nodes

14

How should lymph nodes feel?

- rubbery
- mobile
- small (≤ 1 cm)

15

splenomegaly =

enlargement of the spleen

16

Splenomegaly is present in many hematologic conditions:

- infectious mononucleosis
- Hodgkin's lymphoma
- when spleen takes over for bone marrow to produce RBCs

17

Hemorrhagic conditions and platelets

Insufficient platelets to plug leaking vessels

18

What happens to blood in a hemorrhagic condition (skin/membranes)?

- Blood moves under skin and through mucous membranes
- Produces spontaneous ecchymoses or petechiae

19

ecchymoses =

bruises

20

petechiae =

small red patches

21

thrombocytopenic purpura =

Decrease in circulating platelets in combination with purpura

22

Thrombocytopenic purpura: acute

bleeding from any body orifice
