An Interesting Aside: Sometimes functions that are very different have unexpected connections. An example is the interesting connection between blood clotting and pain transmission, consider: 1) When platelets aggregate, they release serotonin:
2) High molecular weight kininogen (HMK) is one of four glycoproteins in the contact system. HMK is a precursor of the neurotransmitter/hormone bradykinin, a potent vasodialator and diuretic. |
