designed for survival and is regulated by both the neural and endocrine (hormonal) systems. Fundamentally‚ both systems are communication systems that receive sensory information from various sources (eyes‚ ears‚ skin‚ blood‚ etc.) and transmit appropriate responses to specific targets once information has been processed to re-establish balance. The nervous system is a rapid-acting‚ but short-lived communication system that functions by transmitting nerve impulses – it reacts very quickly to stimuli

behavior that the reader is likely to find socially and morally unacceptable. Yet one might argue that Bigger merely responded to the conditions in which he lived and which shaped him. If one advocates such a response‚ Bigger might be viewed as a sympathetic character. My position‚ with respect to this dilemma‚ is that Bigger has a way to control his actions and the actions he chose come with major consequences. Although Bigger had to conceal his slave mentality‚ Bigger should have rebelled against

body cell contents and all metabolic processes taking place inside the body. This process is essential to the survival of a person and to our species as a whole. The liver‚ the kidneys‚ and the brain (hypothalamus‚ the autonomic nervous system and the endocrine system) help maintain homeostasis. An inability to maintain homeostasis may lead to death or a disease‚ for example diseases that can occur due to the result of a homeostatic imbalance include diabetes‚ dehydration‚ hypoglycaemia‚ gout and

1. Kent and Jebreel both ask Danielle out on a date. Kent is very attractive and a lot of fun to be with‚ but he’s also employed. Jebreel is older than Kent‚ has a secure job‚ and owns his own home; however‚ Jebreel is quite unattractive and not very much fun. Daniel chooses to go out with Jebreel instead of Kent.

Lab 34b Cardiovascular Physiology 1. What was the baseline heart rate for the frog? 59-63 bpm 2. Which wave is larger‚ the one for atrial contraction or the one for ventricular contraction? Why? Ventricular. It shows the strength of the ventricle as it pumps blood‚ and it is a thicker muscle to pump stronger as it contracts 3. At what time during the contraction cycle was it possible to induce an extrasystole? The time during the relaxation part of cardiac cycle. 4. By clicking the Multiple

A study was carried out to investigate the effects of exercise on the body. Exercise causes many homeostatic factors to kick in‚ in an effort to maintain internal homeostasis. How exercise affects some of these homeostatic factors can be determined by measuring‚ observing and monitoring certain parameters. For the purpose of this study‚ the factors in which I had to look at included temperature‚ pulse rate and breathing (respiration) rate. In doing the experiment‚ I will be able to see firsthand

1 Chapter 1 INTRODUCTION Alcohol drinking has been practiced in the majority of human society since early times. Alcohol (ethyl alcohol) is a drug which acts principally as a depressant on central nervous system. Its effects on behavior are well known and regular use gives rise to an increased tolerance‚ so that the drinker needs to take gradually increasing amounts to obtain the same effect. Chronic excessive alcohol consumption leads to life threatening hazards (Best‚ 1999). Alcohol related diseases
