Flashcards in Lymph Node Deck (19):
1

Lymphatic Circulation

Deal with the excess tissue fluids (Lymph)

2

Superficial Lymphatic vessels

Follow Veins

3

Deep lymphatic vessels

Follow arteries

4

Cervical Lymph node

Draining the head and neck

5

Axillary

Armpit, filtering lymph from the upper limb

6

Bronchial

Respiratory system airways

7

Mesenterc

Intestines throughout the abdominal cavity

8

Inguinal Nodes

Lymph from the lower limb

9

Lymph Nodes

lymph is modified with white blood cells.
Responsible for production of antibodies against pathogens and phagocytosis removal of foreign matter.
Swelling = Infection in that part of the body

10

Capsule

Loose Connective tissue around the node

11

Afferent Lymphatic vessels

Brings lymph into the node

12

Cortext

Outer part of the node

13

Medulla

Inner part of the node

14

Trabeculae

Extend inward from the capsule, dividing the cortex

15

Lymphatic Follicles

Pale germinal centers that contain high WBC activity

16

Passage of Lymph

Afferent Lymphatic vessels -> cortex -> cortical sinus -> medulla -> medullary sinuses -> efferent lymphatic vessles

17

Hilum

Blood vessels and efferent lymphatic vessels

18

Efferent Lymphatic Vessels

Allow for passage of lymph out of the node
Fewer than afferent, but are bigger in diameter
Include valves for one way flow

19

Passage of Lymph (Body)

ALL Lymph enters the thoracic duct or right lymphatic duct and Drain into the subclavian vein and back to the heart.
Metastasis can be spread in this way.
