Task 1
Conduction Pathway of Heart and its stages
Likewise central heating system with pipes, radiators, pumps and others that use electricity to operate, Human heart also needs electricity to pump the blood in views, arteries, and blood vessels. Human heart also requires electricity power to push and pump blood in blood vessels so is to control the normal working of …show more content…
The vital signs of Alex were 82/40 which is considered as frequent drop out on blood pressure. Moreover the pulse rate of the patient was 130 that are also considered as high heart rate. Whereas, minimal urinary output is observe. The task aims to evaluate appropriate reasons of frequent blood pressure drop out, and increased heart rate just after the accident.
Blood Pressure is dictated by the force of the blood following up on the dividers of the veins or blood vessels. Two components decide the span of this power. One is the volume of blood being pumped through the vessel. The other is the extent of the vessels. Changes in blood pressure can be brought about by either an adjustment in the measure of blood being pumped or by an adjustment in the span of the blood pressure. Body mechanisms modify heart rate and vein enlargement to keep up blood pressure at proper levels. High or low blood pressure results from an inability to manage pulse. A typical reason for hypertension is the development of cholesterol on the surfaces of the veins lessening the volume (Parati & Esler, …show more content…
Vessel systems convey blood to all cells and tissues in a coordinated and directed way. The role of blood vessels in a human body is to develop supply routes for blood flow in the body. These blood vessels are made out of three tissue layers. The thick furthest layer (tunica adventitia or tunica externa) of a vein or course is made of connective tissue. The centre blood vessel layer (tunica media) is thicker and contains more contractile tissue in supply routes than in veins. It comprises of circularly orchestrated versatile fibre, connective tissue and polysaccharide substances. Blood vessels contain valves to keep blood moving towards the heart (Kim, et al.,
