How Does The Difference Between Coronary And Portal Circulatory Differ

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.

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

The circulatory system which is present in the chest consists of heart and blood vessels such as arteries, veins and capillaries (Australian Indigenous Healthinfonet, 2016). The heart being the centre controls the blood circulation throughout the body receives deoxygenated blood through veins which is then converted into or replaced by the oxygenated blood from the lungs and then pumped out by the heart to different organs of the body through arteries. (Australian Indigenous Healthinfonet, 2016). The diseases that affects the normal function and structure of the circulatory system are called cardiovascular diseases (Australian Indigenous Healthinfonet, 2016). It commonly includes diseases such as stroke, coronary or ischaemic heart disease, peripheral vascular disease, heart failure, cardiomyopathy etc. that may be life-threatening ("Department of Health | Cardiovascular disease", 2016).

The cardiovascular system consists of the heart, blood and blood vessels. The cardiovascular system is the major transport of materials to and from the cells. Blood is carried from the heart around the body via the arteries and the blood is then carried back to the heart via the veins. 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.

Coronary Artery Disease, also known as CAD, is the most common form of heart disease. (Heart and Stroke Foundation, 2009) Coronary Artery Disease obstructs the blood flow in vessels that provides blood to the heart which is caused by the buildup of plaque on the artery walls. (Rogers, 2011, p.87) (Heart and Stroke Foundation, 2009) Plaque is a yellow substance that consists of fat substances, like cholesterol, and narrows or clogs the arteries which prevents blood flow. (Heart and Stroke Foundation, 2009) Plaque can build up in any artery but usually favors large and medium sized arteries. (Heart and Stroke Foundation, 2009)

The heart, blood and blood vessels make up the basis of the cardiovascular system also known as the circulatory system. The average human body contains approximately 5 litres of blood which is carried around the body via a network of blood vessels split into three types; arteries, veins and capillaries. The arteries are the largest of the three vessels and carry blood away from the heart. Veins carry blood to the heart and are smaller than arteries, then finally the smallest vessels known as capillaries distribute the oxygen rich blood to organs whilst simultaneously picking up the waste carbon dioxide and water from the organs to transport back to the heart where it can be pumped into the lungs to be exhaled.

Coronary heart disease is one of the leading killers in America. I will later discuss why this is the case, and how the choices of Americans will inflict the ultimate price of death. Aside from bad decisions, the anatomy of where this disease takes place is fragile in regards to bodily malfunctions. The reason it is called coronary heart disease is because it takes place in the coronary arteries. These arteries are what supplies the heart with oxygenated blood. So you can guess that if something goes wrong with these arteries, it could be detrimental for the entire body because the heart pumps blood to the whole body. The right and left coronary arteries branch from the aorta, which is the main supplier of blood to the systemic circuit. The

The cardiovascular system uses blood to transport oxygen, nutrients, and other materials throughout the body. The heart is made of cardiac muscle and is composed of 4 distinct chambers. The right side of your heart collects blood on its return from the rest of our body. The blood entering the right side of your heart is low in oxygen. Your heart pumps the blood from the right side of your heart to your lungs so it can receive more oxygen. Once it has received oxygen, the blood returns directly to the left side of your heart, which then pumps it out again to all parts of your body through arteries (the aorta).

The circulation of blood allows for the transport of nutrients, gases, blood cells and hormones for immunological defense, nutrition, as well as temperature, pH and homeostatic maintenance. The heart muscle circulates blood, a fluid containing erythrocytes, leukocytes platelets and plasma. Since humans have a closed cardiovascular system, gases and nutrients diffuse across blood vessels into interstitial fluid, which then carry these essential components to various cells, while moving cellular waste products away. The arteries transport oxygenated blood from the left ventricle through the aortic semilunar valve. Circulation begins in the aorta, a large, arched, thickset artery that branches into major arteries of the trunk as well as arteries of the lower extremities below the diaphragm. Capillaries are a system of small blood vessels that transport blood to the venous system after distributing

The coronary arteries supply oxygenated blood to the heart muscle. Plaque is a substance that can clog these arteries and cause a condition called atherosclerosis. The buildup of plaque can occur over many years which can ultimately lead to coronary heart disease (CHD). Plaque can harden and cause the arteries to become narrowed. This reduces the flow of oxygenated blood. Plaque may also burst and a blood clot may form causing a blockage of blood flow to the heart. In result to the blockage angina or a myocardium infarction can occur.

Did you know the circulatory system comprises the heart, veins, capillaries and arteries? The system moves pure oxygenated blood in a continuous and controlled way from the lungs and heart so that blood can reaches every cell. Blood travels through a type of network of vessels that include capillaries that permeate every tissue of the body. Once it’s depleted of oxygen, the blood returns to the lungs and heart and the cycle continues.

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

The heart is divided into four chambers; the superior chambers (atria) receive blood and are connected to the inferior chambers (ventricle), through the atrioventricular valves. Once in the ventricles, blood is ejected to the vasculature through the semilunar valves. These valves, similar to the ones in the veins, ensure the unidirectionality of blood flow.

Blood is one of the most vital components of the human body. The blood carries many functions such as to supply oxygen to the bodies tissues, remove metabolic waste products, regulate our core temperature as well as fighting infection and foreign bodies (Glover, 1997). The cardiovascular system is composed of the heart and its vessels. The heart is an involuntary muscle which receives blood to the atrias, which is then pumped via the ventricles. The vessels are composed of three main types. Arteries, veins and capillaries; all which transport blood throughout the entirety of the body. The constant action of both the vessels and heart ensure that the body receives a continuous supply of blood, keeping us within our homeostatic limits.
