Right Atrium Cycle

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

The respiratory system and the cardiovascular system work together by oxygen being inhaled by the mouth and nostrils and then the oxygen enters the respiratory system. When the oxygen enters the respiratory system, oxygen enters the alveoli which are located in the lungs and then it diffuses through the alveolar wall. After when this process is complete, it enters the cardiovascular system. The oxygen is then mixed with hemoglobin, which forms oxyhaemoglobin. The blood is then circulated all around the body. While the blood is mixed with the oxygen, a waste gas gets produced, which is carbon dioxide. The excess gas then exists out by going through the respiratory system and then it is exhaled out from the mouth.

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

 Once the blood cell gets to the superior vena cava it goes through the right atrium and the right ventricle, then through the pulmonary artery and into the lungs.

When the left atrium is filled with blood, the heart contracts and the blood passes through the bicuspid valve and into the left ventricle.

First the de-originated blood goes into the right atrium. And the originated blood goes through the left atrium. The right atrium then pumps blood through the tricuspid valve into the right ventricle, and the left atrium pumps blood through the bicuspid valve into the left ventricle. The right ventricle contracts, semi lunar valve opens and deoxygenated blood travels back to the lungs. The left ventricle contracts, semi lunar valve opens and oxygenated blood goes out to the body.

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 Journey of a red blood cell begins inside the bone, where the blood cell is made which is the bone marrow. The red blood cells travel around the body within capillaries. Then the deoxygenated red blood cell makes its way to the heart in the vena cava. After the blood cell has made its way through the heart the right atrium (the cell enters the right atrium first) contracts and pushes the blood cell through the tricuspid and into the right ventricle (the parts where the blood cell enters second which is located in the bottom right corner of the heart.) Next the right ventricle again contracts and pushes the blood cell out of the heart through the semi lunar (the section of the heart where the cell enters third). Then finally the deoxygenated

Both atria simultaneously fill with blood. Then the bicuspid and the tricuspid valves open, also simultaneously, to allow blood to flow into the ventricles. As the blood collects in the ventricles, they contract, ejecting blood into the lungs and the body. Meanwhile, the atria relax and again fill with blood.

When we breathe, oxygen is absorbed through the lungs into the blood stream. The heart pumps oxygenated blood around the body through blood vessels (arteries). This oxygenated blood travels to all the body’s tissues and releases the oxygen for the cells to function. Cells then expel waste such as carbon dioxide which is then reabsorbed by the blood. This deoxygenated blood is carried back to the heart via veins this is then pumped back into the lungs the waste products are then exhaled and the blood is oxygenated again to be reabsorbed, carried back to heart, to start the process

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

Once through the tricuspid valve the deoxygenated blood travels to the right ventricle. The right ventricle is triangular shape, has thicker walls at the base of the ventricle and thins out towards the atrium this helps with pumping the deoxygenated blood to the pulmonary artery. The pulmonary artery is a large blood vessel, the are two veins for each lungs the blood pumping through the pulmonary artery is brought into the lungs where the deoxygenated blood is altered and oxygen is added turning the blood into oxygenated blood, from there it proceeds into the left side of the heart travelling through the pulmonary vein (one of the only veins that carries oxygenated blood) to the mitral valve the oxygenated through the mitral valve that regulates the blood flow to the left ventricle by two leaflets that are 4-6cm wide. The mitral valve is connected to papillary muscle that is via the the chordae tendineae, the papillary muscle helps to prevent prolapse of the valves systole. The chordae tendineae are string like tendons that connect the papillary muscle to the mitral valve. Once through the mitral valve, the oxygenated blood travels through the left

enters the heart from the lungs via the four pulmonary veins into the left atrium, it then flows into the

The heart is what keeps all living breathing species alive, animals or humans. If the heart was to shut down but the nervous system continued and was active, it would not matter. The entire body would shut down because once the supplier no longer delivers what is needed; organs will no longer function correctly, therefore causing irreversible damage. Arteries are what carried the rich oxygenated blood from the heart to the rest of the organs throughout the body. The Veins are what bring back the carbon dioxide blood to the heart. It then has to be put through a cycle so that it can be shipped back out. Blood travels from the right atrium through the tricuspid valve, to the right ventricle. From there, it is pumped to the lungs, the oxygen-rich blood goes to the left atrium and then through the mitral valve to the left ventricle where it goes to the aorta to be pumped around the body (Colombo 7). What looks to be a complicated process that would take hours or minutes is actually done in a matter a seconds.
