In this task, you are given a sentence. You are expected to write the name of the organism substances in the body mentioned in the input. Although there might be several correct answers, you need to write one of them.

Input: Consider Input:  Thus , when the same organism was detected by both DNA Detection Kit and blood culture analysis , the detected organism was considered an infectious pathogen .

Output: blood


Input: Consider Input:  The agonism of 5 - HT1A receptors , negatively coupled to cAMP , reduces IOP by decreasing the production of aqueous humor , like beta - receptor antagonists which , diminishing the content of cAMP at the postjunctional site , lowers the aqueous humor secretion with a consequent decrease in IOP [ 98 ] .

Output: humor


Input: Consider Input:  Because the ciliary epithelium of the pars plicata is responsible for the secretion of aqueous humor , an obvious function for these two receptors would be an involvement in the control of aqueous production and , consequently , of the IOP level .


Output: humor
