foods high in saturated fat that can raise your cholesterol should be avoided. Hypertension is another risk factor that can be controlled and overcome. Hypertension is when the heart contracts and the pressure is high enough in the arteries and veins that there is risk of rupture on an aneurism. Usually if this is the case the heart is working too hard and needs to be controlled with diet or medication. In most cases a low sodium diet or medications that contain a Beta blocker can be introduced

decrease respectively. Normally a person perspires to cool off. This causes him to lose fluid and become dehydrated. As a result‚ the body has to come up with another way to cool off‚ so the blood vessels dilate. This lowers the pressure within the veins‚ allowing the blood to cool. Caffeine is a stimulant and causes increased HR‚ and when a person exercises‚ their heart rate increases. All of this is to meet the body’s metabolic needs‚ producing adequate perfusion. Heart rate is brought back to homeostasis

During this process the blood going to his extremities is being rerouting away from the dermal surface to a network of deep veins wrapped around deep arteries. When this occurs diffusion known as countercurrent exchange begins which traps heat closer to the body core and limits heat loss to the environment by reducing the temperature gradient between the arterial blood and the

Tympanoplasty is a procedure to repair a hole in your eardrum (tympanic membrane) using a piece of tissue from another part of your body (skin graft). The tympanic membrane is a thin layer of tissue in your ear that can tear or become punctured. As a result‚ a hole can develop and can allow water and germs to enter your middle ear. This can cause infection. The goal of tympanoplasty is to restore hearing and prevent future infections. LET YOUR HEALTH CARE PROVIDER KNOW ABOUT: • Recent colds or

rate will move blood through the body more quickly and will stimulate the baroreceptors. An increase in arterial pressure causes an increase in firing of the arterial baroreceptors which will decrease sympathetic outflow to the heart‚ arterioles‚ veins‚ and increase parasympathetic outflow to the heart. 3.

The cardiac conduction system of the heart consists of specialized muscle cells that generate and send rhythmic electrical impulses to the myocardium in order for the heart to contract (Cardiac Conduction System‚ 2016). When there is the normal rhythm of the heart it is called sinus rhythm and any deviation from sinus rhythm is called an arrhythmia (Saladin‚ 2012). Electrocardiograms (ECG) record the electrical impulses and help determine when there are any abnormalities in the way the heart functions
