Write An Essay On The Cardiovascular System

The cardiovascular system also known as the circulatory system consists of the heart and blood vessels. One of the most important jobs it has is to “circulate” blood. The heart works to pump the deoxygenated blood to the lungs for gas exchange while simultaneously pumping oxygenated blood to the body’s tissues. The blood vessels work to continuously bring the blood to all areas of the body which helps regulate body temperature. The flow of oxygenated blood to the tissues helps deliver nutrients such as amino acids and electrolytes, water and oxygen. Also, it’s responsible for removing metabolic waste from the cells and disposing of carbon dioxide. The cardiovascular system’s anatomy varies throughout the body and is connected by the arteries, veins, and capillaries. The main organ of the cardiovascular system is the heart. It 's located in the upper torso, chest area, as are some of the body 's major blood vessels. One main blood vessel is the Femoral Artery, it 's role

Aneurysms are when a weakened area in the arterial wall begins to expand or dilate. When the artery bursts, tissues can get damaged because the oxygenated blood doesn’t get to them and there can be massive internal bleeding that may lead to death. Congestive Heart Failure (CHF), is excessive buildup of fluid in the lungs or organs due to inadequate pumping in the heart. The fluid leads to swelling that clog the organs. Mechanical malfunctions of the heart is when there is a lack of oxygen to the myocardium that leads to the inability of the heart to pump or contract in an area. If the area is large enough, the heart can die. Electrical malfunctions of the heart is the heart pumping too quickly, too slowly, or an irregular heart rhythm.

The assessment process for evaluating a cardiac arrest patient is check for pulse, check if the patient is breathing, determining alertness (AVPU) by tapping their leg then begin CPR immediately, use an AED on the patient and applying a bag-valve-mask with
