Discuss The Difference Between The Atria And Two Ventricles

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 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

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 heart is located beneath the rib cage, between the lungs, to the left of the sternum (breastbone). Most people believe that the heart is located on the left side of the chest because the bottom of the heart is tipped to the left. Therefore, you feel more of your heart on the left side. The heart is a powerhouse with muscular walls that contract, thrusting blood throughout the body’s blood vessels. The blood must flow in one direction in order for the heart to function properly. The three focal types of vessels are arteries, capillaries, and veins which form the circulatory system. These vessels, like elastic tubes, transport blood to every portion of the body. Arteries carry oxygen-rich blood away from the heart to all of the body’s tissues. They progressively become smaller as blood is carried further away from the heart. The capillaries are the small, thin blood vessels that connect the arteries to the veins. Nutrients, carbon dioxide and waste products are allowed to pass to and from the tissue cells by their thin walls. Veins, on the other hand, carry the oxygen-poor blood back to the heart. These vessels gradually become larger as they get near to the heart. The blood vessel system runs over 60,000 miles long.

The fetal circulatory route is connected to the mother’s circulatory system. The mother does the work that the baby’s lungs will do after birth. Blood enters through the placenta, picking up oxygen before returning to the fetus. It returns to the fetus through the umbilical vein. The core concept behind fetal circulation is that fetal hemoglobin has a higher affinity for oxygen than does adult hemoglobin, which allows a diffusion of oxygen from the mother’s circulatory system to the fetus. The mother is not directly connected to that of the fetus, so the placenta functions as the respiratory center for the fetus as well as a site of filtration for plasma nutrients and wastes. The uterine arteries carry blood to the

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

The circulatory blood flow is divided into two sections. The pulmonary circulation it consists of blood vessels that are responsible for the transportation of blood through the lungs to be oxygenated and they return the waste gases picked up along the way and then returned through the body blood vessels for the arrival trip back to the heart The pulmonary circuit is a short loop that rapidly oxygenates the blood. It leads from the heart's right half to capillary beds in both lungs, and then returns to the heart's left half. In the circulatory system there is a path of blood that flows, blood from the body’s tissue it enters on the via the superior and inferior vena cava the right atrium. The

As the heart uses a larger amount of blood, over time the left ventricles adapts and grows. This causes it to hold more blood, and ejects more blood per beat , even when your not exercising, at the same time certain muscles are contracting and relying on type two muscle fibers and the arteries expand each time the ventricles pump blood out from the heart. With that it helps increase the amount of oxygen you breath, which causes a quicker supply of oxygen and helps remove waste from your body.

From the right atrium the blood moves into the right ventricle through the AV valve. When the ventricles contract the blood is moves through the semilunar valve into the pulmonary artery. This artery then branches off into the left lung and the right lung so that the blood can become oxygenated. The oxygen-rich blood returns to the left atrium of the heart through the pulmonary veins.

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.

The heart has two parts each with a left and right form (meaning four total): the auricle and ventricle. Knowing this, though it may seem backwards, it is helpful to consider various characteristics of the veins and arteries that are intimately connected with these parts. There are two veins, the pulmonary vein and the vena cava. There are two arteries as well, the aorta and the pulmonary artery. The way these function together, as Harvey demonstrated, is that the vena cava takes blood into the right auricle. This blood is pushed into the right ventricle, where it cycles through the lungs from the pulmonary artery and arrives at the left ventricle through the pulmonary vein. From here, the blood is pushed into the left ventricle where is distributed to the body through the aorta. These are the purposes and functions of the various veins and arteries

On the right side the flow of blood enters the heart through the inferior and superior vena cava that throws out the poor oxygen blood to the right atrium. On the left side of the heart the pulmonary veins takes action that dumps the rich oxygen blood that is coming from the lungs to the left atrium. This has both sides of the heart working together. When it comes to the atrial contraction, the right side makes the blood flow to the right atrium to the right ventricle to the tricuspid valve. Once the ventricles fill up completely, that is when the tricuspid valves shut closed. This is to prevent the blood from going backwards to the atria, making the ventricles squeeze together. The left side of the atrial contraction makes the blood flow from

The journey of the blood through the heart begins at the point when deoxygenate blood returning from the body is entering the hearts via the superior and inferior vena cava. From the right atrium the blood passes to the right ventricle via tricuspid valve. At this point ventricular contraction begins and forcing blood out of right ventricle via opened the semilunar valve. Blood is further pumped to the lungs via the pulmonary arteries. In lungs, blood collects oxygen and release the CO2. Oxygenated blood is returning to the left atrium through pulmonary veins and is carried to the left ventricle through biscupid valve. When contraction of heart happens again the blood from left ventricle is forced to the aorta and leaves the heart. Blood circulates

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

The heart is one of the earliest differentiating and functioning organs of the human body. In human embryos, the heart will develop from the mesoderm and begin to beat in a little over three weeks.1 When the heart is fully formed, it will be about the size of a large fist and will serve as the circulatory pump for the body.2 In this role it aids in pulmonary circulation where blood is sent to the lungs to be oxidized and in systemic circulation where blood is sent throughout the body. This process is highly regulated by electrical signals and this paper seeks to understand some of the physical phenomenon that can explain this.
