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.

Both the right and left atrium contract causing blood to flow though the two valves, and then into the left ventricle. The left ventricle pumps blood into the systemic circulation through the aorta. This systemic circulation system is much bigger than the pulmonary circulation system, which is why the left ventricle is so big. The blood on the left side of the heart is oxygenated. It becomes oxygenated when the deoxygenated blood passes through the right atrium and then flows into the left ventricle. It is then pumped along the pulmonary artery into the lungs where it is oxygenated. It then travels through the pulmonary veins back into the heart. It enters through the left atrium and then travels to the left ventricle. This process is repeated over and over again, to make blood continuously flow through the heart, lungs and body. This process ensures that there is always enough oxygen for the body to work

Now, let's talk how the heart works. The heart is divided into two halfs. Each side has a upper and a lower chamber. The upper right chamber revives poor-oxygen blood from the body. The lower right chamber pumps

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

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

In a normal human being the heart correctly functions by the blood first entering through the right atrium from the superior and inferior vena cava. This blood flow continues through the right atrioventricular valve into the right ventricle. The right ventricle contracts forcing the pulmonary valve to open leading blood flow through the pulmonary valve and into the pulmonary trunk. Blood is then distributed from the right and left pulmonary arteries to the lungs, where carbon dioxide is unloaded and oxygen is loaded into the blood. The blood is returned from the lungs to the left

form the pulmonary veins, which return the oxygenated blood to the left atrium. Backflow of

Pulmonary circulation transports deoxygenated blood from the right side of the heart to the lungs where the blood picks up oxygen and returns

Next stop. Right atrium. One of the four chambers of the heart, the right atrium lets deoxygenated blood to pass through the tricuspid valve into the right ventricle and from there to the lung to oxygenate. The tricuspid valve, also known as right atrioventricular valve is located between the two chambers and it looks like flaps that blocks blood flowing back into the atrium. (Yahoo Health, 2013) The right ventricle of the heart has the mission to pump the blood into the pulmonary artery via the pulmonary valve and pulmonary trunk right into the lungs. Ready to go through the pulmonary valve into the pulmonary artery? Here we go! Weeeee…..

Arteries: carry blood away from heart; oxygenated except for pulmonary circulation and umbilical vessels of fetus

7. A human heart is a muscular organ and its job is to pump not only de-oxygentaed blood to the lungs but also pump oxygenated blood to the body. The blood that is de-oxygenated within a human first arrives to the heart through the Inferior or Superior Vena Cava to the right Atrium of the heart. Then as the Right Ventricle relaxes, the blood gets pumped into the right Ventricle which will then contract forcing the blood out into the Pulmonary arteries that will take the de-oxygenated blood to the lungs.

The pulmonary vasculature contains arteries and arterioles, which branch in the lungs to create a dense capillary bed to provide blood flow. The pulmonary capillary bed is a high-volume, low-pressure, low-resistance system that delivers blood to and from the lungs via the arterial and venous circulation systems. The right ventricle of the heart is responsible for pumping blood to the pulmonary artery and to the lungs so it can be oxygenated while the left ventricle pumps oxygenated blood to the tissues. Typically, hypertension refers to high blood pressure in the systemic circulation, however, an increase in blood pressure may also occur in pulmonary circulation. The pulmonary artery supplying blood to the lungs can become narrowed,

The human body is a very complex organism composed of different types of systems and functions. All the functions that each system has, is what makes possible for the body to obtain life. One of the most important systems in one’s body is the circulatory system, where the heart, the lungs, and the blood vessels work together to form the circle part of the circulatory system. The pumping of the heart forces the blood on its journey. The body’s circulatory system really has three parts: pulmonary circulation, coronary circulation, and systemic circulation. Each part must be working independently in order for them to all work together. However, when one of the parts of the circulatory system does not

Arterial blood is oxygenated in the circulatory system found in the lungs, left chambers of

The heart pumps blood from the left ventricle into the aorta, this is transported through the aortic valve, and this only allows each heartbeat to be a one-way bloody flow. The aorta carries and distributes oxygen-rich blood to all arteries, most of which branch off from the aorta, with the one expectation of the main pulmonary
