Human Anatomy & Physiology II (BIO-139) Laboratory Exercise #12 Due Date: Wed. 3/31 Text: Chapter 17 : The Endocrine System A Challenge in Definitions 1.) Interstitial Fluid: Interstitial Fluid is essentially a mixture of water, ions, and small solutes that are forced out of the blood plasma by the systolic pressure that is created as the heart pumps. 2.) Endocrine Cell: Endocrine cells are responsible for producing and releasing hormone molecules into the blood stream. 3.) Simple Diffusion: This is the process that takes place when solutes are moved along a concentration gradient in a solution or across a semipermeable membrane. 4.) Capillary Filtration: Capillary Filtration is essentially the main force that drives fluid transport between the capillaries. 5.) Hormone Receptor: A hormone receptor is a molecule that binds to a specific hormone. 6.) Second Messenger System: This is the system that is implicated in adaptation. This includes intracellular calcium, as an example.
