Flashcards in Lymphatic System (FINAL) Deck (17):
1

What is the function of the lymphatic system?

Function of the Lymphatic System

  1. Immune function = immunity
  2. Drain and filter fluid via nodes

2

What type of fluid does the lymphatic system filter and drain?

Filters and drains lymph fluid

  • Lymph fluid = extracellular fluid 
    • Fluid outside the cells 

3

What are the two types of extracellular fluid?

Types of Extracellular Fluid? 

  1. Plasma
    1. In the blood = plasma
    2. Out of the blood = lymph
  2. Interstitual = tissue fluid
    1. In the tissue = interstitual fluid
    2. Out of the tissue = lymph 

4

What is the general definiton of lymph nodes?

Lymph nodes = where you filter lymph fluid

5

What is the purpose of lymph nodes?

Purpose of Lymph Nodes

  • To remove pathogens with WBCs

6

What are pathogens?

Pathogens = disease causing organisms

 

7

What types of WBCS are in the lymph nodes? 

"Never Let Monkeys Eat Bananas"

  • *Neutrophils (40-70%)
  • Lymphocytes (20-49%)
  • Monocytes (4-8%)
  • *Eosinophils (1-4%)
  • *Basophils (<1%)

* granulocytes

8

What is an afferent pathway?

Afferent pathway = in/towards

9

What is an efferent pathway?

Efferent Pathway = out/away

10

Term for lymph nodes of the neck?

Cervical nodes = neck lymph nodes (tonsils) 

11

What is the term for lymph nodes of the armpit? 

Axillary lymph nodes

12

What is the term for lymph nodes of the groin? 

Inguinal lymph nodes

13

What is the term for lymph nodes of the elbow? 

Supratrochlear lymph nodes

14

What is the term for lymph nodes of the pelvis? 

Pelvic cavity lymph nodes

15

What is the term for lymph nodes of the abdomen? 

Abdomenial Cavity Lymph Nodes

16

What is the term for lymph nodes of the chest? 

Thoracic Cavity Lymph Nodes

17

What does a swollen lymph node indicate

Swollen lymph nodes indicate:

  • Infection due to an increase of WBCs
    • In order to filter out more lymph fluid
