Deoxygenated Blood Differences

The oxygen rich blood returns from the lungs and it goes through the pulmonary vein to the left atrium.

It begins at the base of the heart’s right ventricle and is approximately 3 cm in diameter and 5 cm in length (Yahoo Health, 2012). It then splits into the left and right pulmonary arteries. The right pulmonary artery delivers oxygen depleted blood to the right lung. From the right pulmonary artery I have made it to the right lung. Once in the lung I will travel South West to reach the lower lobe of the right lung.

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.

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

Which blood vessel shown in the figure carries oxygenated blood to the lower thoracic cavity and the abdominal cavity of the body?

Blood then travels out toward the lungs for oxygenation via the pulmonary artery and returns to the heart through the pulmonary veins entering the left atrium. It is pumped through the mitral valve into the left ventricle to exit the aortic valve to the circulation via the aorta. The questions asked in the lab packet directly related to the anatomy and physiology of the heart which allowed to understand how the heart works as a

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

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.

Left ventricle pumps the blood into the aorta, where the blood is supplied to the body tissues by the systemic arteries.

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

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

As blood travels through the circulatory system, it is first pumped from the right side of the heart to the lungs through the pulmonary arteries and then separates into arterioles which split into capillaries. Here, the deoxygenated

The first main vessel that leaves the heart is the pulmonary artery and is the only artery that carries de-oxygenated blood and traveling through the lungs is then oxygenated and returned to the heart by the pulmonary vein and that is the only vein in the body to carry oxygenated blood. The now oxygenated blood leaves from the heart by the aorta and the splits to the carotid artery also known as the subclavian artery to the arms and the thoracic artery. The carotid artery leads to smaller arteries, arterioles and continuous capillaries around the arms and head and lead back to the heart first through the fenestrated capillaries, venule and medium sized veins and back to the largest vein that is called the jugular vein that is also known as

The aorta is the largest artery of the body. Its job is to disperse blood to smaller arteries to be sure all of the parts of the body receive an efficient supply of well oxygenated blood. This artery connects to the aortic valve of the heart. This valve opens and closes, so blood can leave the heart. It has to close completely and open widely for the right amount of blood to be able to flow through. If there are any problems with it, and it can't push through blood from the aorta, a person might end up needing aortic valve replacement surgery.
