What is the difference between serous fluid and pots?

Think About It: Perhaps you should rephrase your question? Serous fluid is the protein rich fluid, like lymph. Pots are made of metal for cooking, plastic or ceramic for plants.

Don't know re: POTS?: Am not familiar with this acronym - only one i know for it is postural orthostatic tachycardia syndrome, which has nothing to do with serous fluid, which is fluid that is a result of mild inflammation or allergy without infection. Medically, we refer to fluid as either serous or exudative, with the latter meaning something more serious - infection, cancer or severe inflammation.

Do you mean pus?: Serous fluid is normal clear yellowish body fluid that may weep out of an open or healing wound. Pus is infected cloudy fluid with bacteria & white blood cells & can smell badly. Don't know if that was your question though.
