Name:Grade and Section: Use the video above and the notes we gave you to fill in the appropriate structures of the Endocrine System (all lower case letters). testes ovaries pancreas adrenal gland thymus thyroid pituitary gland pineal gland Fill in the blanks using the notes above. The Endocrine systemA collection of glandsthat produce and secrete hormones.The function of the system is to maintain the correct chemicallevel in the body through feedback.Regulates mood, sleep, growthand development, metabolism, sexual function and reproductionprocesses.Glands:A group of cells that monitor (test) the bloodstreamfor chemicalimbalance.Produces and releases hormonesinto the bloodstream to tell target cells to balance chemicals.Types of Glands:exocrine glands- ducted and releases products into ducts. Ex. sweat, tears, digestive juicesEndocrine glands- ductless and secrete products directly to the bloodstream. Ex. HormonesHormones:Chemical messengers thatcommunicate information from one set of cells to another.Many different hormones move through the bloodstream.Each type of hormone is designed to affect only certain cells. Click on each description and decide if it applies to the Nervous system or the Endocrine system. Endocrine system of glands hormones are transmitted through the blood stream slow, but chemical response lasts longer slow communication because messages travel through the bloodstream relies on chemical messages to be sent through the bloodstream has a widespread effect as hormones travel throughout the body long lasting effects as hormones stay in blood for a long time Nervous signals travel along neurons brain, spinal cord, and nerves short-acting changes to the body fast communication because nerve impulses travel fast relies on electrical impulses precise messages as nerve impulses travel to a specific area short lasting effect as impulses disappear once they are delivered Match the Endocrine system gland with its description. Pituitary gland the "master gland"; regulates many other glands through hormone release Thyroid gland regulates metabolism by secreting thyroxine Adrenal gland releases the hormone adrenaline for flight or fight response Pancreas releases Insulin which regulates the levels of glucose in the blood
