Lymphatic System
|
___________ is a major player in Immune response.
*The production, maturation, storage, and release of defensive white blood cells |
|
Lymphatic System
|
- Returns excess interstitial fluid with leaked plasma proteins back to the Blood stream
|
|
Interstitial fluid
|
- liquid found between the cells of the body
|
|
Lymph (Clear water)
|
- Once Interstitial fluid has entered Lymphatic Vessels it is called_____________.
|
|
What are the biggest Veins?
|
Superior Vena Cava + Inferior Vena Cava
|
|
Kidney
|
- An Organ that filters Clean Blood
|
|
Lymphatic Vessels
|
- A one-way system in which Lymph flows toward the Heart
Types: - Microscopic, permeable, blind-ended capillaries - Lymphatic collecting vessels - Trunks & Ducts |
|
Lymphatic Capillaries
|
-Permeable
-Contain Minivalves that function as one-way gates |
|
Minivalves
|
- Allow interstitial fluid to enter Lymph Capillaries
- Do NOT allow Lymph to escape from the Capillaries |
|
Lymphatic Capillaries
|
During inflammation, _______________ can absorb
-Cell debris -Pathogens -Cancer cells |
|
Lymph Nodes
|
Cells in the _______________ Cleanse and "Examine" the debris
|
|
Lacteals
|
Specialized lymph capillaries that are in Intestinal Mucosa (lamina propria)
*Absorb digested fat & deliver chyle to the blood |
|
Chyle
|
is a milky bodily fluid consisting of lymph and emulsified fats
|
|
Right Lymphatic Duct
|
A Duct that drains the right upper arm + the right side of the head & thorax
|
|
Thoracic Duct
|
A duct that drains the rest of the body
|
|
Lymph Transport
|
> Lymphatic System lacks an organ that acts as a pump
> Vessels are low-pressure > Uses same methods as veins too push lymph: - Respiratory pump - Muscular pump |
|
Lymphocytes
|
The main cells that are involved in the Immune Response
Two main cells: -T Cells + B Cells |
|
T Cells & B Cells
|
Cells that protect the body against Antigens
|
|
Antigens
|
Anything the body perceives as foreign such as:
- Bacteria & their Toxins - Viruses - Mismatched Red Blood Cells or Cancer Cells |
|
T Cells
(T Lymphocytes) |
- Cells that manage Immune Response
- Attack & destroy infected cells |
|
B Cells
( B Lymphocytes) |
*Cells that produce Plasma cells, which secrete antibodies (gamma globulins, immunoglobulins)
*Antibodies immobilize Antigens |
|
Edema
|
Fluid Built up
* Lymphatic Vessels remove this fluid built up |
|
Lymph Nodes
|
*Will swell up and can physically feel them.
Found in: -Inguinal -axillary (armpit) -Chest - Cervical -Major Blood Vessels |
|
Lymph Nodes
|
______________ are placed within Connective Tissue & clustered along lymphatic vessels
Functions: * Filtration * Immune system activation |
|
FIltration
|
* Macrophages destroy microorganisms & debris
|
|
Immune System Activation
|
* Monitor for antigens and launch an attack against them
|
