How To Write An Essay On The Cardiovascular System

Improved Essays
The cardiovascular system is the bodies system that is in charge of regulating blood throughout the body. The main job of the cardiovascular systems are transportation of blood which allows the body to receive oxygen, nutrients, and hormones while disposing of wastes. The second job of the cardiovascular system is protection via the white blood cells. White blood cells clean up cellular debris and fight pathogens that have entered the body. The cardio vascular system will also offer protection through the blood carrying antibodies of immunity for previous infections in the body. The final function of the cardiovascular system is regulation. Blood vessels control the homeostasis of the body, an example of this is blood vessels control the amount …show more content…
Many people will refer to the blood vessels as the body’s highways. This is because the blood vessels allow blood to quickly travel to all parts of the body and back again quickly. There are three major types of blood vessels in the human body. The first are the arteries which face high blood pressure levels due to the fact that they take blood away from the heart, Because of this they are thicker and more elastic then the other blood vessels. Branching off of the arteries are arterioles which carries blood to the second type of blood vessels the capillaries. These are the smallest and thinnest of the three types of blood vessels but also the most common in the body. They can be found running through almost every tissue in the body. Capillaries carry blood very close to the cells of the tissues of the body in order to exchange gases, nutrients, and waste products. The final type of blood vessels are the veins. Veins are seen as the counter part of the arteries ad their job is to pump blood back to the heart from the outer parts of the body. Veins rely on gravity, inertia, and the force of skeletal muscle contractions to help push blood back to the heart because of the fact that once the blood reaches them the blood pressure is so

    Blood is classified as a fluid connective tissue that travels through the cardiovascular system to provide nutrients to the body’s organs and tissues. Blood is composed of two major components: formed elements and plasma. Formed elements, such as erythrocytes, leukocytes and platelets, are suspended in a watery nonliving fluid matrix that travels throughout the body’s arteries and veins. Leukocytes, also known as WBCs, are primarily used in the defense against diseases and infections; while platelets contribute to clotting factors at the site of vessel wall injuries. Erythrocytes, also known as RBCs, are a major component of O2 delivery to the brain.…

    The arteries (carries blood away from the heart) have thick muscular walls and small passage ways. They contain blood under high pressure. The last blood vessels is the capillaries (found in the muscles and the lungs). They are one cell thick, and have low blood pressure. Being one cell thick allows gaseous exchange to happen in them.…

    The right ventricle squeezes the blood to pass through the pulmonic valve and the pulmonary artery to reach the lungs where it picks up oxygen. The oxygenated blood comes back to the left atrium and passes through the mitral valve to reach the left ventricle. The walls of the left ventricle have to compress to pump the oxygenated blood to the aorta which supplies the rest of the body. When the process fails heart failure may occur and the walls of the left ventricles can become thicker and thicker, and at the end not able to perform its normal function.…

    In the closed circulatory system, blood never leaves the arteries, capillaries, and veins. This system is pressurized and needs multiple arteries and veins. Evolutionists believe that once an animal could no longer diffuse its water and nutrients, it evolved to an open circulatory system, then it evolved to the superior closed circulatory system. This theory may seem reasonable at first, but looking deeper, it displays that the circulatory system relies on too many complex components. Even the organs that are involved in the circulatory system, like the heart that is responsible for pumping blood, or the endocrine system that releases hormones into the circulatory system, are dependent on oxygenated blood themselves.…

    Blood Pressure Blood pressure , as a physiological variable of humans, is a hydrostatic pressure, utilized by blood on the walls of blood vessels.(Tortora and Derrickson 2011). It is caused by the contraction of the ventricles and the amount of blood in the whole cardiovascular system. The mean blood pressure (the average pressure in the cardiac cycle) is coordinated in order to provide adequate blood transfer to the tissues.(Saladin,2001). The decrease of blood pressure is followed by an increase of heart rate. The normal blood pressure is 120 mm HG systolic and 80 mm HG diastolic blood pressure There are three main types of blood pressure regulation considering homeostasis: Neural regulation…
