demand of oxygen throughout the body and this could cause a heart attack or the person may slip into Acoma. (GCSE success, 2006).
When breathing rate is extremely slow it is known as bradypnoea. This can also be caused by a disruption within the signal of the nerves from the medulla oblongata. If the breathing rate remains slow oxygen will not get to the rest of the body quick enough and could cause the person to faint. When adrenaline is released within the body it causes bronchodilation which widens the tubes to the lungs to allow more oxygen to pass through freely. This will ensure that gaseous exchange preforms adequately. (Manual of clinical paramedical procedures, 2010).
Activities such as exercise can lead to negative feedback loops interacting with different aspects in the internal environment of the body. Such as the ones I have mentioned; temperature, heart rate, blood pressure, breathing rate and blood glucose levels. The medulla oblongata is an extremely important organ. As it controls the nervous system and manages our bodies heart rate and our breathing rate and by giving chemical and nerve signals; it can change the way our bodies react. Some of the actions the medulla oblongata controls are muscles contracting and relaxing and blood vessels dilating and constricting. This takes place during exercise. There are different aspects that may make it difficult for the body to perform homeostasis.
During exercise the body temperature of the human should not reach to a threatening limit in which tissues will become damaged. However, Homeostasis then occurs to attempt to prevent this. While exercising muscles contract and extract there for generating heat within the body and also affects the human metabolism. During the body’s attempt to maintain homeostasis the heart increasingly begins to pump blood around the body in an attempt to reallocate the heat in which the body is making while exercising and also to help to quickly pump oxygen to the muscles to reduce carbon dioxide build up.
It is very important for the body to remain in its natural state within its internal environment because there are certain outcomes that may occur. For example if the body gets to hot then this will eventually cause problems with the nervous system and may cause the brain and heart to stop functioning. If the heart rate keeps beating to fast, which happens during exercise; it could lead to cardiac arrest. So in order to counteract this, the body will releases hormones that will attempt to slow this down and blood vessels will then dilate. If our breathing rate is too low then the body will also try and counteract this by speeding up the breathing rate if this happens then we would have to much oxygen in our body and not enough carbon dioxide for diffusion to occur. Also too much oxygen could be travelling top the brain, in which we could then faint. If homeostasis does not occur here, blood glucose levels may become too low then energy will not be...
