Brachial artery

Different application of MRI can be used such as Flair, which is as normal MRI imaging, but this is where you take scans of the brain and the computer can take away any fluid present in the image, so what you are left with in the image is just brain tissue, which will let you see lesions, or origins of a hemorrhage. The diagnostics of hyper acute infarction and ischaemia is mainly done by diffusion –weighted imaging (DWI). DWI is sensitive to diffusion of water molecules within tissue. The…

Homeostasis is a key factor in helping the body to maintain optimum conditions for life. It aids in keeping a steady environment inside the body when the external environment is constantly changing. ( Peate, I. and Nair, M. 2011) Humans need to maintain a near constant environment internally to be able to function and to survive. There are various control systems at work in the process of homeostasis, such as negative feedback and the receptor, controller and effector loop. The receptor,…

The purpose of this experiment was to understand osmosis, however, the deeper importance was that it could be compared to a real cell in our body. The egg in this lab can represent a red blood cell. When cells such as red blood cells are placed in pure water, water enters them through osmosis and they swell up. If this continues for a long period of time, they have a great chance of bursting. On the other hand, when cells are placed in a lower concentrated solution, water leaves them through…

Introduction This experiment will examine the effects of age and gender on blood pressure. Blood pressure is the force of blood against the inside walls of the arteries. As blood moves throughout the body, it pushes against these walls, keeping it moving throughout the body (Mader, 2016). As the arteries become narrower, due to a buildup of plaque, the pressure on the inside walls increases and blood pressure rises. This can result in hypertension, or high blood pressure, which forces the heart…

internal jugular veins as well. As the external jugular veins descend through the lateral neck, they pass obliquely over the sternocleidomastoid muscles and then empty into the subclavian veins. The brachiocephalic vein a vein that returns oxygen-depleted blood from the upper limbs, neck, and head to the heart. There is a brachiocephalic vein on the left side of the neck and one on the right. The two brachiocephalic veins merge together with the azygos vein, which carries deoxygenated blood from…

Physiology What conditions contribute to turbulent blood flow or heart murmurs. Turbulent blood flow occurs as blood moves through narrowed or leaking valves producing a swooshing sound over the precordium and a high heart rate combine with narrowing, causing the heart to handle a larger amount of blood flow than normal; the basis is increased blood velocity, structural valve malfunction, or atypical chambers. Some pathological causes of heart murmurs are anemia, high blood pressure,…

Doctors currently know why people can die from a broken heart. Rob Stein from The Washington Post reported that researchers have revealed that trauma “Can unleash a flood of stress hormones that can stun the heart causing sudden life threatening heart spasms in otherwise healthy people” (Study Suggests You Can Die of a Broken Heart 1). Rob Stein proclaims that stress hormones can alarm the heart, putting people’s lives at risk. According to Stein, the rush of stress hormones to the heart is…

1. Auscultation method provides a closer to true value systolic blood pressure (SBP). Despite the existence of a potential auscultatory gap, where an underestimation of SBP can occur, crosschecking with the palpation method can eliminate this potential error. The palpation method as well is also subjected to many sources of error, such as strength of the pulse, location etc., and it requires the cuff to be more deflated, giving a lower systolic pressure reading, making it only a good estimate.…

need it. If the body does not have a key factor like oxygen to carry out its duty, it cannot function properly. In the next couple of paragraphs, I will be discussing the perfusion exemplars such as congestive heart failure, hypertension, coronary artery disease, and traumatic brain injury.…

Implantation of a stent within a coronary artery alters the local hemodynamics modifying the shear stress upon the endothelium. 14 Low endothelial shear stress causes a phenotypic change in which can induce a phenotypic switch in the smooth muscle cells from contractile to secretory as well as increase migration into the intima and proliferation. 15 Overall, regular or high endothelial shear stress maintains the contractile phenotype of the smooth muscle cells therefore inhibiting neointimal…
