Immune system organs and functions
Immune system plays a major role in killing an entering pathogen in our body. Our Immune system is performing by various parts of immune organs in our body. They are White blood cells , Antibodies , Complement System , Lymphatic System ,Spleen, Bone marrow and Thymus .
Organs of Immune system
Functions of Immune organs :
* White Blood Cells :
white blood cell plays a major role in immune system it is produced in Bone Marrow and all parts of Lymphatic System .
white blood cells moves through out our body with the help of Blood and Tissues searching for pathogens like Bacteria ,Virus etc.... to attack and kill them .
white blood cells includes Lymphocytes [ B cells , T cell ].
* Antibodies :
Antibodies helps our body to fight microbes\ toxic substances produced by entered foreign microbes , antibodies mark it as antigens for destruction . Antibodies destroys the antigen with the help of proteins.
* Complement System :
complement system is fully made up of protein it helps Antibodies in the destruction of Antigens .
* Lymphatic System :
lymphatic system is a network of special tubes throughout the body the main functions of lymphatic system are
*Absorb some of fats in our diet from the intestine .
*React to pathogens[ Bacteria,Virus etc...] .
*Deal with Cancer Cells.
*To manage Fluid level in the body .
Lymphatic system is a tube made up of tissues and white blood cells [lymphocytes].
* Spleen :
The Spleen is a Blood filtering Organ the filters and removes microbes and destroys Old and Damaged Red Blood Cells . spleen produce Antibodies and Lymphocytes the main disease fighting component in immune system.
* Bone Marrow :
Bone marrow is a Spongy Tissue found inside your Bones . It produce RBC [Red Blood Cells],WBC [White Blood Cells ], Platelets .
* RBC to carry Oxygen throughout our body.
* WBC to fight against infections, microbes etc...
* Platelets to help our Blood clot.
* Thymus :
The Thymus Filters and Monitors your Blood Content and produce White Blood Cells called as T Lymphocytes.
Apart from these Organs the body has OTHER WAYS to defense itself against microbes.
