A&p 2 Lymphatic System

Front 1

List the 3 functions of the
Lymphatic system

Back 1

1) Collect Fluid from tissues & return to circulation.
2) Part of Immune system
3) Transports lipids from small intestine

Front 2

Lymphatic capillaries

Structure?

Function?

Back 2

Closed end vessel, no tight junctions
Overlapping epithelial cells

Pressure pushes cells apart to allow
fluid, molecules, cells to enter

Front 3

Collecting vessels

Structure?

Function?

Back 3

Filter lymph through lymph nodes
Drain to collecting ducts

Front 4

Lymphatic trunks

Structure?

Function?

Back 4

6 large vessels

Collect lymph for specific areas

Drain into collecting ducts

Front 5

Areas drained by thoracic duct

Back 5

legs, abdomen, left side of chest, arm, head

Drains to left subclavian

Front 6

Areas drained by
Right lymphatic duct

Back 6

Lymph from right side of chest, arm,
head

Drains to right subclavian

Front 7

Lymphatic tissue--MALT
Structure?

Location?

Back 7

In connective tissue
MALT=mucosa-associated-lymph-tissu

Protects mucous membranes of digest
respirtory,urinary, reproductive tracts

Front 8

Lymphatic nodule
Structure?

Location?

Back 8

Dense masses lymph cells
Temporary
Found in lymph organ: nodes, tonsils,
appendix, Peyer's patch/sm.intestine

Front 9

Explain function of Lymph node parts:

Fibrous capsule?

Back 9

Surrounds node
Separates from other tissue
Inside-connective fiber network that holds lymph cells

Front 10

Lymph node parts:

Cortex?

Back 10

Contains lymph nodules
full of lymphocytes for dense

Front 11

Lymph node parts:

Medulla?

Back 11

Many macrophages to phagocytize

Front 12

Lymph node parts:

Afferent lymph vessels?

Back 12

Carry into node

Front 13

Lymph node parts:

Efferent lymph vessels?

Back 13

1-3 vessels
Carry filtered lymph out

Front 14

Causes & symptoms of

Lymphadenitis?

Back 14

Inflammation of node
Caused by infection
Swollen, painful nodes

Front 15

Causes & symptoms of

Elephantiasis?

Back 15

Blocked node
Extreme edema
Causes thicken skin & fibrosis
Irreversible
Mosquito-worm, blocks vessel

Front 16

Causes & symptoms of

Metastatic cancer?

Back 16

Cancer cells in lymph
Trapped in node
Not destroyed, cancer cells grow in node
Can be removed w/ tumors

Front 17

Front 20

Functions of
Tonsils?

Back 20

Sample inhaled & ingested stuff
Activate immune system if needed.

Front 21

Cells found in

Cortex of Thymus?

Back 21

Maturing T cells
Separate from blood stream

Front 22

Cells found in

Medulla of Thymus?

Back 22
