1

What is the function of the lymphatic system? (2)

-Provides defense against pathogens.
-Recycles fluid and other nutrients, which are lost from the cardiovascular system, into the venous system for reuse..

2

The lymphatic system is composed of: (4)

-Lymph
-Lymphatic vessels (lymphatics)
-Lympoid tissues and organs
-Red bone marrow

3

Lymphatic vessels found in most areas of the body except: (4)

-CNS
-Splenic pulp
-Bone marrow
-Cornea

4

Function of Lymph node?

Filter lymph

5

Pale yellow fluid which is similar in composition to interstitial fluid.

Lymph

6

Transport Lymph.

Lymphatic vessels

7

Site of lymphocyte production.

Red bone marrow

8

Originate as Microscopic lymphatic capillaries in the space between cells are are found in most parts of the body.

Lymphatic vessels

9

Unite to form larger structures called lymphatic vessels.

Lymphatic capillaries

10

Are structurally adapted to ensure the return of proteins, which leak out of blood capillaries to the cardiovascular system.

Lymphatic capillaries

11

Have a unique structure that permits interstitial fluid to flow into them, but not out of them.

Lymphatic capillaries

12

Are lymphatic capillaries larger or smaller than blood capillaries?

Slightly larger.

13

End blindly, unlike blood capillaries which are continuous with arterioles and venules.

Lymphatic capillaries

14

Resemble veins in structure, but have a thinner wall and more valves than veins.

Lymphatic vessels

15

Contain lymph nodes at various intervals along their length.

Lymphatic vessels

16

Deliver lymph into two large vessels called lymphatic ducts.

Lymphatic vessels

17

Drain into subclavian veins

Lymphatic ducts

18

Sac like chamber at the inferior end o the thoracic duct.

Cisterna Chyli

19

Is a specialized form of loose connective tissue that contains lymphocytes.

Lymphoid tissue

20

Large masses of lympoid tissue that are not surrounded by a capsule.

Lymphoid nodules (lymphatic follicles)

21

Lympoid nodules that are scattered throughout the mucous membranes.

(MALT) Mucosa-associated lympoid tissue

22

Cluster of lympoid nodules in the lining of the small intestines.

Aggregated lympoid nodules (Peyer's Patches)

23

Large lympoid nodules in the pharynx.

Tonsils

24

How many tonsils do we have?

5

25

Types of Tonsils?

-Palatine tonsils (left and right)
-Lingual tonsils (left and right)
-Pharyngeal tonsil (adenoid)

26

Formed by the 5 tonsils

Waldeyers ring

27

Are srrounded by a capsule that is composed of dense connective tissue.

Lymphoid organs

28

Small lymphoid organs located along lymphatic vessels.

Lymph Nodes

29

Outer cover of lymph node.

Capsule

30

Bundles of collagen fibers that extend from capsule to interior of the lymph node to divide the lymph node into compartments.

Trabeculae
