A Brief Note On Atherosclerosis And Cardiovascular System

There are different types of circulation, two of which are systemic and pulmonary circulation. Systemic circulation pumps oxygen rich blood from the heart and into the aorta, which travels down in front of the spinal column and into the abdomen. Two coronary arteries branch off and divide into smaller networks of arteries to provide oxygen to heart muscles. However, pulmonary circulation carries oxygen-poor blood and divides into right and left branches on the way to the lungs to fill the blood with oxygen.

Likewise, Blood flows from the right atrium to the right ventricle, and then is pumped to the lungs to receive oxygen. From the lungs, the blood flows to the left atrium, then to the left ventricle, forming the complete circulation.

The hearts function as a double pump that serves two circulations. The pulmonary pump in the right side of heart is provided for the gas exchange in the body, and the systemic circulation in the left side provides the functional blood supply to all body tissues. The functional blood to the heart is provided by the coronary arteries. Right coronary artery supplies the heart through the posterior interventricular and marginal artery branches; and the left coronary artery supplies the heart via anterior interventricular artery and the circumflex artery. The myocardium is drained by great, small, and middle cardiac veins which

Composed of the heart, blood vessels, and blood, the cardiovascular system is the body system that carries out the tasks of pumping and transporting blood, oxygen, nutrients, and waste products, and other substances throughout the body.

Pulmonary circulation is the circulation of the deoxygenated blood through the pulmonary arteries and oxygenated blood through the pulmonary veins. Each organ gets a supply of blood and this is because each organ has an arterial and venous. “The systemic circulation comprises all the blood vessels not involved in the

The cardiovascular system consists of the heart, blood vessels and 5 liters of blood that the blood vessels transport. The cardiovascular system is transporting oxygen, nutrients, hormones and cellular waste products through the body. The cardiovascular system is powered by the hardest working organ the heart.

Blood flows from the tissues → superior and inferior vena cava → right atrium → tricuspid valve → right ventricle → pulmonary semilunar valve → pulmonary artery → lungs → pulmonary veins → left atrium → bicuspid (mitral) valve → left ventricle → aortic semilunar valve → aorta →body tissue.

The circulatory system is by definition the system of organs and tissue, including the heart, blood, blood vessels, lymph, lymphatic vessels, and lymph glands involved in circulating blood and lymph through the body (Dictionary). However, the heart has a very specific function that is involved in the system; the heart 's function and parts will be broken down into detail in following paragraphs.

The systematic system also circulate the deoxygenated blood from the body and into the heart to start the pulmonary circuit again. The blood is pumped from the left ventricle, into the aortic valve and then into the aorta. The aorta branches into the major arteries to the upper body before going through the diaphragm, where it branches into arteries, which supplies blood to the lower body parts.

The systemic circulation is the movement of the blood from the heart through the body to provide oxygen and nutrients, and bringing deoxygenated blood back to the heart. The systemic circuit is a longer loop that starts from the heart's left half and

In the systemic circuit blood returns from the lungs into the left atrium. Once in the left atrium blood flows though the left atrioventricular valve into the left ventricle. The left ventricle then contracts and the aortic valve opens because of the contraction. Blood then flows through he aortic valve into the ascending aorta and then once in the aorta it is then sent to every organ in the body where it excretes oxygen and intakes carbon dioxide. Finally, the carbon dioxide rich blood returns itself to the heart for the process to reoccur again. Both circuits must always maintain circulation so that blood can be constantly disbursed throughout the body (The Heart, Slide 11

The cardiovascular system consists of the heart, blood, and valves. The cardiovascular system is able to transport things such as oxygen, nutrients, cell wastes, hormones and other substances vital for the maintenance of homeostasis as well as cell life through blood. The hearts function is to pump the blood in and out of the heart to propel it throughout the rest of the body. Deoxygenated blood enters through the pulmonary circuit through the superior and inferior vena cavae and dumps into the right atrium, then travels through the tricuspid valve into the right ventricle through the pulmonary semilunar valve and out of the pulmonary arteries. When the blood exits the pulmonary arteries into the lungs, gas exchange occurs. Oxygenated blood enters the systemic circuit through the right and left pulmonary veins into the left atrium, through the bicuspid or mitral valve into the left ventricle through the aortic valve and out of the aorta to the rest of the body and back again. The valves of the body carry the blood and help to manage blood pressure throughout the

The two major cardiovascular circuits in the human body is the pulmonary circuit and the systemic circuit. Both of these circuits work together in order to make the body function properly. The major difference between these two circuits is where the blood travels and what areas of the body the blood reaches. The pulmonary circuit carries blood to only the lungs which focuses more on gas exchange. The systemic circuit carries blood to the tissues in the entire body which focuses more on supplying the tissues with oxygen and nutrients. Another interesting fact that separates these two circuits is the blood itself and the process that which it flows. At the beginning of the pulmonary circuit, the blood is deoxygenated. The oxygen poor blood then

Arteries and Arterioles: Arteries are blood vessels that carry blood away from the heart. Blood carried by arteries is usually highly oxygenated, having just left the lungs on its way to the body’s tissues. The pulmonary trunk and arteries of the pulmonary circulation loop provide an exception to this rule – these arteries carry deoxygenated blood from the heart to the lungs to be oxygenated.

There are 2 primary circulatory loops in the human body which include pulmonary circulation loop and the systemic circulation loop. The pulmonary circulation transport deoxygenated blood from the right side of the heart to the lungs. During pulmonary circulation blood picks up oxygen and returns to the left side of the heart. The right atrium and the right ventricle support the pulmonary circulation loop. The systemic circulation carries highly oxygenated blood from the left side of the heart to all of the tissues of the body. During systemic circulation it then removes wastes from body tissues and returns deoxygenated blood to the right side of the heart. The left atrium and the left ventricle of the heart support the systemic circulation loop.
