blood has got red blood corpuscles,white blood cells, platelets and serum

blood cells are manufactured in bone marrow and liver and spleen and stored in splanchnic organs

when ever there is a need for more blood blood moves from sphlanchnic organs

blood moves from heart thorugh arteries to arterioles and reaches cells

in the cells they supply oxygen and theron go to veins through venules . until this all of us know our basic biology.

what we do not know is in the cells the extra spillage is drained by lymph and lymphatic channels acts as gutter and ferry lymphy with stops and storage in lymph glands.

in the event of toxic crisis blood moves into third space which are interstitial spaces in bwteeen cells and gets clogged there unable to be drained.

in acute pancreatitis there is a systemic shock which lead to toxaemia which leads to reduced blood pressure and reduced blood to end organs
