Deoxygenated Blood Journey

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

 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 left ventricle contracts, sending the blood to the aorta. The blood is then sent to the rest of the body. On the right side of the heart, the tricuspid valve separates the right ventricle and the right atrium allowing blood to enter the ventricle but not flow backward to the atrium. Blood flows through the pulmonary arteries to go to the lungs. On the left side of the heart, the mitral valve separates the left atrium and the left ventricle. Blood flows from the left ventricle to the aorta through the aortic valves and to the rest of the body. Arteries carry blood with oxygen and other nutrients throughout the blood. Veins take blood back to the heart, which pumps it to the lungs in order to get oxygenated. The heart arteries which are called the coronary arteries provide oxygen and nutrients to the heart muscle the right coronary arteries supply blood to the bottom and the back of the heart. The left coronary arteries split into two vessels. One branch supplies blood to the front of the heart the other branch provides blood to the left side of the heart. An electric system transmits signals throughout the heart to control what is pumping. The electrical signals pass down tot the end of the heart in the ventricles pathways carry this signal throughout the muscle so they can track at the same time to pump blood to the lungs and throughout 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

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.

Once deoxygenated blood enters the right atrium, it travels through the tricuspid valve into the right ventricle. Then the blood goes through the pulmonary semilunar valve into the pulmonary arteries. Once in the pulmonary arteries the blood is pumped into the lungs where it is then oxygenated. The blood goes from the lungs through the pulmonary vein into the left atrium. From there it passes through the bicuspid valve into the left ventricle where it is then pumped out through the aortic semilunar valve into the aorta (Drake 101). From the aorta the blood goes to the right and left coronary arteries.

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).

Heart has 4 chambers, 2 atria and 2 ventricles. De-oxygenated blood comes back to the right side of the heart with the venous circulation, pumped into the right ventricle and then to the lungs, there, carbon dioxide is released and exchanged with oxygen. The oxygenated blood then travels back to the left side of the heart into the left atria, heading to left ventricle, aorta, and finally arterial circulation. Blood travels from right side to left side via the lungs only.

As the ventricle contracts, blood leaves the heart through the pulmonic valve, into the pulmonary artery and to the lungs where it is oxygenated blood then passes through the aortic valve into the aorta to tissues and body organs.
