The Aort Obstacles Of The Human Body

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

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.

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

The heart is basically a pump that has to circulate the blood around the body delivering oxygenated blood to our organs and then returning deoxygenated blood to our lungs. There are four chambers in the heart, two atria and two ventricles. There are four main valves, mitral, aortic, tricuspid and pulmonary7b.

Oxygen poor blood fills the right atrium from either the superior or inferior vena cava.

The right atrium is where the process begins. Then, blood travels through the tricuspid valve to the right ventricle, and from there to the pulmonary artery. Once the blood travels through the pulmonary artery, it reaches the lungs. While in the lungs, the blood goes through a gas exchange: deoxygenated blood gets oxygenated (The gas exchange takes place in the alveoli, which are tiny air sacs in the bottom of the lungs

The left side of the heart, has the left atrium and ventricle that takes in oxygenated blood from the lungs and pumps it out of the aorta.

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.

in the lower half of the heart. The ventricles pump blood to the lungs and the rest of the body.

Blood comes from the Superior and Inferior vena cava, into the right atrium. As the right atrium fills with blood, it contracts and the tricuspid valve opens and the blood pumps into the valve. When the right ventricle is full the tricuspid valve close to ensure blood moves in the right direction. The blood then moves to the right ventricle and into another valve called the Pulmonary valve. Then moves to the pulmonary artery and into the lungs. The blood moves into the lungs and picks up fresh oxygen. Then it returns to the left heart through the pulmonary veins to the left atrium. It passes through the mitral valve and enters the left ventricle. Oxygenated blood moves into the aortic valve and into the Aorta to reach all parts of the body ( heart.org).

The left chamber, lower at the heart, takes in oxygenated blood through the mitral valve from the left atrium while it contracts. The aortic valve leading to the aorta is closed while this occurs. At the same time, the aortic valve leading to the aorta is closed giving the ventricle the opportunity to fill with blood. The ventricles contract as both ventricles are full. When the left ventricles contract, the aortic valve opens as the mitral valve closes. When the mitral valve closes it prevents blood from coming back into the left atrium and the opening of the aortic valve giving way for the blood to flow into the aorta. From there it goes throughout the body. The left and right ventricles also contract together, but when the left ventricle

has to work harder pumping blood to the rest of the body. Blood in our

Deoxygenate Blood enters the heart through two large veins, the inferior and superior vena cava, emptying oxygen-poor blood from the body into the right atrium of the heart.

Before understanding the physical theories behind the heart, it is useful to understand a little bit about the physiology of the heart. The heart is divided into four chambers: two atria on top and two ventricles on the bottom. The atrium and ventricles are separated by valves and the septum separates the right and left sides of the heart.3 Blood returns to the heart from the body through the veins, enters the right atrium and then flows to the

The heart is divided into four chambers: The right atrium and left atrium are the upper chambers of the heart. The right ventricle and
