A Simple Guide to Thymus Disorders, Diagnosis, Treatment and Related Conditions

This book describes Thymus Disorders, Diagnosis and Treatment and Related Diseases"In the secret places of her thymus gland Louise is making too much of herself. Her faithful biology depends on regulation but the white T-cells have turned bandit. They don't obey the rules. They are swarming into the bloodstream, overturning the quiet order of spleen and intestine. In the lymph nodes they are swelling with pride.
It used to be their job to keep her body safe from enemies on the outside. They were her immunity, her certainty against infection. Now they are the enemies on the inside. The security forces have rebelled. Louise is the victim of a coup. Will you let me crawl inside you, stand guard over you, trap them as they come at you?Why can't I dam their blind tide that filthies your blood?Why are there no lock gates on the portal vein?The inside of your body is innocent, nothing has taught it fear.
Your artery canals trust their cargo, they don't check the shipments in the blood. You are full to overflowing but the keeper is asleep and there's murder going on inside. Who comes here?Let me hold up my lantern. It's only the blood; red cells carrying oxygen to the heart, thrombocytes making sure of proper clotting. The white cells, B and T types, just a few of them as always whistling as they go.
The faithful body has made a mistake. This is no time to stamp the passports and look at the sky. Coming up behind are hundreds of them. Hundreds too many, armed to the teeth for a job that doesn't need doing. Not needed?With all that weaponry?Here they come, hurtling through the bloodstream trying to pick a fight. There's no-one to fight but you Louise. You're the foreign body now."Jeanette WintersonThe thymus is a specialized organ of the immune system.
The immune system's function is to protect the body against infectionsThe immune system uses the lymphocytes, It contributes to the development of T lymphocytesThe thymus educates T-lymphocytesTo fight in the body against any parasitesEach T cell attacks a different antigenThey will find their own pathogenEach T cell attacks a foreign substanceWhich it identifies with its receptor evidenceT cells that attack the body's own proteinsAre eliminated in the thymus after being screenedFirst T cells undergo Positive SelectionThose are destroyed with no interactionSecond the T cell undergoes Negative SelectionRemoved are those T cells with high affinity interaction-An original poem by Kenneth KeeThe thymus is made up of 2 identical lobes and is sited anatomically in the anterior superior mediastinum, in front of the heart and behind the sternum.
The thymus may spread to the neck region where it is linked to the thyroid gland. This is because of the development history of the thymus which has its beginning in the brachial entoderm. The thymus is a transient organ with immune and endocrine function (part of endocrine system that produces hormones). It extends to its largest size at the time of puberty when it stops to grow, slowly shrinks and almost disappears.
The thymus teaches the T-lymphocytes to fight against invaders of the body.
