Answer: Homeostatic regulation refers to adjustments in physiological systems that are responsible for the preservation of a constant internal environment. This enables cells to maintain metabolism and the chemical environment that stabilizes the living state. Learning Outcome: 1-7 Bloom's Taxonomy: Analyzing 2) During exercise, blood flow to skeletal muscles increases. The initial response that increases blood flow is automatic and independent of the nervous and endocrine systems. Which type of homeostatic regulation is this? Why? Answer: The initial increase in blood flow to active muscles is an example of autoregulation. For example, when oxygen levels decline in a tissue, the cells release chemicals that dilate local blood vessels. This dilation increases the rate of blood flow and provides more oxygen to the region even before responses from the nervous or endocrine system take place. Autoregulation does not require the nervous or endocrine system. Learning Outcome: 1-7 Bloom's Taxonomy: Analyzing

Answer: Dynamic equilibrium is defined by a system that is capable of adapting and adjusting to changing conditions in order to maintain a normal range of values. In thermal regulation at equilibrium heat loss is equal to heat production. As circumstances changing and our bodies experience more muscle contraction we increase heat production. In order to maintain equilibrium the body must shed excess heat produced by the muscles so that heat loss and heat production are again equal or in equilibrium.
