Ventricles Vs Right Atrium

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

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

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

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

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.

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

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

This valve opens to allow blood to flow from the right atrium to the right ventricle (Higgins, Roos & Ovid Technologies, 2006).

The circulation of blood starts off in the superior vena cava and goes into the right atrium, it then goes through the tricuspid valve into the right ventricle, through the pulmonary valve into the pulmonary artery , into the lungs and in the left atrium into the left ventricle to the aorta and to the rest of the body.

The left ventricle of the heart supplies most of the heart’s pumping power, and is vital for the normal function of the heart (American Heart Association, 2015). The heart pumps oxygenated blood from the left atrium to the left ventricle, which supplies the rest of the body’s

In a healthy functioning heart the blood flows from the superior and inferior vena cava the right into the right atrium. Blood flows from the right atrium pass the tricuspid valve into the right

Fish have a two-chambered heart with one atrium and one ventricle. Oxygen diffusion occurs in the gills. Amphibians have a three chambered heart with two atria and one ventricle. Reptiles have a four chambered heart with two atria and two ventricles. However, there is mixing of blood because the ventricle separation is incomplete. Birds and mammals both have a four chambered heart. All of these hearts contain valves and the rest of the body receives blood through arteries (which carry oxygenated blood away from the heart) and veins (which carry deoxygenated blood back to the heart) and capillaries (where the two meet). The cardiac cycle is the period during which the heart fills with blood and pumps it out. During one cycle, it receives deoxygenated

The atria are smaller than the ventricles and do not have as muscle as the ventricles. The atria are also known as the receiving chambers. They are connected to the veins that carry blood to the heart.

Right Atrium: The upper right hand side chamber of the heart. It receives blood returning to your heart from either the body or the lungs. The right atrium receives deoxygenated blood from the superior and inferior vena cava.
