Flashcards in Topic 13 - Lymphatic System Deck (26):
1

Overview

includes

  • lymph vessels + organs
  • T & B lymphocyutes
    •  protect body against bacteria, viruses, cancer cells

2

List the majorextracellular fluids

  1. Blood plasma
  2. Interstitial fluid (ISF)
  3. Lymph

3

blood plasma

fluid in blood

4

Interstitial Fluid (ISF)

bathes cells (except blood cells)

5

Lymph

where is it located?

inside lymphatic vessels

6

Lymphatic Circulation

1 (ISF)

  • how is ISF formed?
  • how much of ISF goes where?

ISF - formed by capillaries leaking plasma

  • 90% re-enters blood in capillaries + venules
  • 10% into lymphatic circulation (now called lymphs)

7

Lymphatic circulation

2 (lymph)

  • where does lymph enter?
    • what does that connect to?

  • enters lymphatic capillaries (closed ended vessels)
  • lymphatic capillaries connect to lymphatyic collecting vessels (have valves)

8

lymphatic circulation

lymphatic capillaries connect to lymphatyic collecting vessels (have valves)

  • what filters what?
  • what is transported away from _____ and to where?

  • lymph nodes along vessels filter lymph (bacteria, debris)
  • transport lymph fluid away from tissues to:
    1. right lymphatic duct
    2. thoracic duct

9

transport lymph fluid away from tissues to right lymphatic duct

  • ?

lymph from right head, chest, + arm

  • drains into right subclavian vein reentering circulation

10

transport lymph fluid away from tissues to thoracic duct

  • ?

lymph from below ribs + left body

  • collecting vessels from below the ribs converge to an enlarged lymph vessel = cisterna chyli 
  • thoracic duct drains into LEFT subclavian vein reentering blood circulation

11

collecting vessels from below the ribs converge to an enlarged lymph vessel is called the ____ _______

cisterna chyli (the beginning of the thoracic duct)

12

lymphatic circulation starts at the

lymphatic capillaries

13

 lymphatic circulation 

from lymphatic capillaries to the:

lymphatic collecting vessels (with valves)

14

lymphatic circulation 

from lymphatic collecting vessels (With valves) to

lymphatic ducts

15

lymphatic circulation

from lymphatic ducts to 

subclavian veins

16

Lymphatic tissues and organs

What are the primary lymphatic organ and tissues?

  1. red bone marrow
  2. thymus gland

17

Lymphatic tissues and organs

  • What are the secondary lymphatic organ and tissues?
  • what happens here?

 

  1. lymph nodes
  2. spleen
  3. mucosal associated lymphoid tissue (MALT)

 

it is where lymphocytes proliferate

18

PRIMARY LYMPHATIC ORGAN + TISSUE

red bone marrow

  • lymphocytes arise here
  • B lymphocytes mature and proliferate (mitosis) here

19

PRIMARY LYMPHATIC ORGAN + TISSUE

thymus gland

  • T lymphocytes mature and proliferate (mitosis) here

20

SECONDARY LYMPHATIC ORGAN + TISSUE

lymph nodes

name its locations

  • locations:
    • cervical
    • axillary (armpit)
    • inguinal (groin)
    • intestinal 
    • pelvic

21

SECONDARY LYMPHATIC ORGAN + TISSUE

spleen

  • filters blood
    • e.g. removes bacteria

22

SECONDARY LYMPHATIC ORGAN + TISSUE

mucosal associated lymphoid tissue (MALT)

  • e.g. tonsils, appendix, lymphoid tissues on mucous membranes
  • tonsils 
    • adenoids = pharyngeal
    • palatine 
    • lingual

23

tonsils

adenoids = pharyngeal

1

nasopharynx

24

tonsils

palatine

how many?

where is it located?

fact: 

  • 2
  • in oropharynx 
  • commonly removed

25

lingual

how many?

where is it located?

  • 1
  • base of posterior part of tongue

26

what does MALT stand for 

musosal associated lymphoid tissue
