In this assignment, I am going to explain the concept of homeostasis in detail and explain the homeostatic mechanisms for regulation of heart rate, Boyd temperature, breathing rate and blood glucose levels. Moving in from this I will evaluate the importance of homeostasis in maintaining the healthy functioning of the body. Primarily, homeostasis is the maintenance of our constant internal environment despite the external changes. Therefore, the internal environment generally comprises blood, tissue fluid, body cell contents and all the metabolic processes taking place. The meaning of the word constant within the concept of homeostasis is more flexible and dynamic, referring to the chemical and physical arrangement being kept within a limited…show more content…
These act as an accelerator and a brake on the heart. However, the sympathetic nervous system alone is active when the body is undergoing muscular work, fear or stress. Therefore, it causes increases in strength to each heartbeat and increases to happen to the heart rate. Moreover, the parasympathetic nervous system at the time of resting, peace and contentment is active as well as calming the output of the heart. Also, if the main parasympathetic nerve speeds up the heart beat it is severed. The hormone adrenalines boost the sympathetic nervous system at the time of fright, flight and fight. Therefore, these two systems supply a specific bunch of excitable cells within the higher section of the right atrium, known as the SA…show more content…
Also, the skin plays a role within this homeostatic mechanism for regulation as it relays nerve impulses. These are maintained by the sensory receptors that are in the skin for heat or cold, these receptors letting the brain know of any changes that occur within the environment. Primarily, the metabolic process that occur within the body are what produce the heat. Energy that is released in the process of chemical reactions, is used to drive processes of muscle contraction such as the pumping of the heart, breathing movement and nerve impulses. Some of this is always released as a form of heat. Also, the liver is where a large amount of these chemical reactions take place as this produces a great amount of the bodies heat. This does not make the human body constantly feel hot as the heat is distributed around the body by the blood that is circulating. However, heat is produced within the body in more than one way and can be gained from the food that we eat; these only consisting of hot food and hot
