located on top of your kidneys‚ and they perform an important management function within your body. Adrenal glands secrete the hormone known as cortisol‚ which is used in the regulation of blood pressure‚ heart activity‚ metabolism and the immune system. These glands also produce aldosterone‚ which regulates electrolytes and bodily fluids. Whenever you exercise or feel stressed‚ your adrenal glands kick into gear‚ producing various levels of adrenaline. When things go wrong with your adrenal glands

Hypertension is caused by Pitta imbalance in the body levels & anger is the psychological manifestations of Pitta imbalance (Nagrajan‚ Srinivasan‚ & Nagendra‚ 2014). The SNS activation is controlled by the Limbic System which also processes emotion. The processing of music also takes place in Limbic System. According to the Sämänya viçeña siddhänta - the similar factors or rasas leads to Augmentation of a rasa. And the dissimilar factors or rasa reduces it. (Loon‚ 1981).

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

the rate of contraction. Autonomic nervous system The heart is controlled by the autonomic nervous system which is two branches called the sympathetic nerves system and the parasympathetic nervous system. The sympathetic nervous system is active when the body is undergoing muscular work such when we are doing exercise‚ like when running or jumping. It causes the increase in the heart rate and strengths the heartbeat. The parasympathetic nervous system calms the heart down and is active when

range. In this instance the brain and the nervous system help to get our internal environments back to its normal state. An example of this is when an individuals body is too hot and our body begins to sweat in order for us to cool down. Our internal receptors react to make sure that we can return to out normal level. These receptors are needed in the negative feedback loop to help send a message about environmental stimuli to our central nervous system‚ after this our bodies then send signals

Negative feedback as a form of regulation Feedback control systems This occurs when a n important variable sometimes known as a key variable e.g. pH of blood and tissue fluid‚ deviates from the accepted range from the accepted range or limits which then triggers responses that return the variable to within the ‘normal range’. Deviation produces a negative response to counteract the deviation. An example of a negative feedback system within the body is the liver when blood glucose levels fall

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
