Nervous System Research Paper

3. The nervous system is an important part of the human body, meaning that the body cannot function without it. The main functions of the nervous system are receiving sensory input, integrating information, controlling muscles and glands, maintaining homeostasis and establishing and maintaining mental activity. The brain, spinal cord, sensory organs and all the nerves that are involved within these organs, are all part of the nervous system. All these organs are what controls the body, as well as passing information around them. The central nervous system, is where all information is processed and where decisions are made. In contrast to the peripheral nervous system, as this system observes what goes on inside the body as well as outside, …show more content…
This is because the body relies on the nervous system to detect any problems that are occurring within the body, so that if there is any changes internally or externally, then this system can respond to those changes. The way the nervous system responds is by communication. So by passing the information to other systems, to help maintain the internal environment. McGraw (1997)
One of the variables that is controlled by the nervous system is blood pressure. The way blood pressure works is by the blood being spurted onto the blood vessel walls at a force. The blood is forced into the arteries when the ventricles contract in order for the pressure to reach a systolic pressure. After the ventricles contract they will then relax, which means the blood pressure will drop to the lowest value called the diastolic pressure.

The endocrine system is highly important, as blood pressure is also affected by a variety of hormones and the endocrine system needs to constrict these hormones at a slower pace.
4. The field of practice that I was in for my first placement was a medical ward. On this type of ward, there was a variety of illnesses, but the main issue was heart failure and high blood pressure. Due to these issues, it meant that the Ramipril medication was used considerably.
The reason why patients that have heart failure or high blood pressure are on Ramipril medication is because it is an angiotensin-converting enzyme inhibitor. This medication blocks the release of the aldosterone substance that causes blood vessels to tighten, meaning that this medication will eventually relax the muscles around the small arteries. This will result in the arterioles expanding, meaning the blood will flow through easily and lower both the blood pressure and the blood and oxygen supply to the heart will increase. Health24 (2013). Ramipril is known to lower blood pressure, as it decreases vascular tone. Another result from this medication is that when the aldosterone is inhibited, the sodium and water reabsorption decreases resulting in a secondary reduction of blood pressure. Mckenry, L, et al
