What is lymphatic system
a one way system of vessel that carries intercelluar fluid and proteins from intercelluar spaces to the blood
|
what are the lymphatic organs?
red bone marrow,thymus gland, lymph nodes, spleen, tonsils, peyers patches
|
What is lymph propelled by
Pulsations of nearby arteries and Contractions of smooth muscle in the walls of the lymphatics.
|
Lymphatic system consists of three parts.
1. A network of three parts
2. Lymph 3. Lymph nodes |
what is the function of tonsils
collect and destory pathogens
|
|
where does the lymphatic system dump intercelluar fluid?
it dumps into the subclavian veins and then into the vena cava.
|
what is the function of red bone marrow?
they contain stem cells that can differentiate into T cells and B cells
|
Lymphocytes
The main warriors of the immune system
|
Functions of the Lymphatic system.
Returns interstitial fluid and leaked plasma proteins back to the blood.
|
what is the function of peyers patches?
lymphatic tissue found in the intestines that helps rid the body of pathogens that we ingest
|
|
what are the four functions of the lymphatic system?
1. it absorbs excess tissue fluid and returns it to the bloodstreams.
2.in the small intenstine, lymphatic cappilaries absorb the building blocks of fat-glycerol and fatty acids. 3.it produces, maintains,and distribute lymphocytes(b and t cells) 4. it helps defend against pathogens |
what is the function of the thymus gland?
T cells mature here
|
Two main types of Lymphocytes
T Cells And B Cells
|
What is a one way system, lymph flows toward the heart?
Lymphatic vessels.
|
what is edema?
swelling. intercelluar fluid is trapped in the tissues.
|
|
what do lymph nodes do?
they filter out bacteria, cancer cells, and other pathogens from entering the blood stream.
|
What is the function of the lymph nodes?
collect and destroy pathogens
|
What protects against antigens?
T cells and b cells protect against antigens.
|
what are the types of lymphatic vessels.
Lymphatic capillaries
Lymphatic collecting vessels Lymphatic trunks and ducts. |
what is the function of red bone marrow?
they contain stem cells that can differentiate into T cells and B cells
|
|
what do lymph nodes produce?
they produce lymphocytes to destroy the trapped pathogens.
|
what is the function of the spleen?
destroys red blood cells and contains lymphocytes that help clean the bood of foriegn pathogens
|
Macrophages
Phagocytize foreign substances and help activate T-cells
|
What is similar to veins, except Have thinner walls, with more internal valves.
Lymphatic collecting vessels
|
what is the function of the thymus gland?
T cells mature here
