Document Summary
Provide examples for each type: homeostatic mechanisms, negative feedback: counteracts any change (anything acting against the set point/normal range) Control center: tells your body how to react to situation, ex: hypothalamus. "set point" - how to tell what the balance is: ex: temp is 98. 6. Effector: coping mechanism, ex: cold weather causes you to shiver. How many are there: 11 organ systems (digestive, reproductive, circulatory, respiratory, endocrine, nervous, etc. ) 3: how does the vertebrate heart work, distributes hormones, transport gases, transport nutrients, helps to regulates body temperature with blood flow, assists in wound healing, vertebrate heart consists of four muscular chambers. Veins: blood away from heart, walls are thicker, walls are more elastic, branches to arterioles, blood to heart, walls are thinner, valves that prevent. Less muscular backflow: branches into venules, describe the role of the lymphatic system, thoracic duct enters a vein that leads to the superior vena cava, superior vena cava, thymus.
