Introduction Respiratory system of human beings is accountable for ensuring supply of oxygen andother necessary gases in the human body. Present report describes about mechanism forregulating the ventilation and pulse rates. In addition to that process of redistributing of bloodduring exercise has also explained. Moreover, changes in the artery structure that is associatedwith the circulatory diseases has explained. Furthermore, relationship between circulatorydiseases and environmental factors has been explained. Along with this changes in therespiratory structure associated with the respiratory disease have been mentioned. With this,relationship between the respiratory diseases and environmental factors have also beenexplained.4.1 Explaining The mechanisms for regulating the ventilation and pulse rates.The breath is known as completely mechanical process. There is separate mechanism forcontrolling the ventilation and pulse rates. However these can be controlled by the nervoussystem which is located in the medulla. The nervous system consists of brain and the spinal cord.Through the neurones electrical impulses are transmitted around the body which make bodycapable to deal with convinced situation . Sympathetic and the parasympathetic both are twosides of nervous system (Naieni, Wu and O’Malley, 2016). They both perform differentfunction that sympathetic nervous system function is to speeds things up and parasympatheticnervous system function is to slows things down. This process can be noticed at the times ofstress and fear and this oftenly refereed to as 'Flight or Fight'. For example, when the brainsenses the danger, then electrical impulses will be send down to the spinal cord and alongneurons which will dilate the pupils for better vision. Apart from this breathing rates can bemaintained normally at a invariant level involuntary by the medulla . On the medulla the rate ofbreathing is depends which assist in deducting the pH level in blood. When PH level is detectedthen medulla find out how much carbon di oxide is present in blood. Breathing rate can beincreased at the time when high PH level is detected and lower of breathing is due to thedecrease in nervous stimulation. Stimulation coming from the heart sympathetic andparasympathetic nervous system help in controlling the heart rate by both the balance. 4.2 Explaining the process of redistributing blood during exerciseAt the time of performing exercise blood flow in body enhanced because of increase inheart rate. During exercise time blood flow increases more then 80% and in rest time blood flows1
