The different between the different routes is that the fatal circulation is a circulation of blood that passes through the body of the fetus and to and from the placenta through the umbilical cord. The Portal circulation is a general term of denoting the circulation of blood through a larger vessel from the capillaries of one organ to those of another that also applied especially to the passage of blood from the gastrointestinal tract, pancreas, and the spleen through the portal vein to the liver. The Systemic circulation is the flow of blood from the left ventricle through the aorta, carrying oxygen and nutrient material to all the tissues of the body, and returning through the superior and inferior venae cavae to the right atrium.
Pulmonary circulation is the circulation of the deoxygenated blood through the pulmonary arteries and oxygenated blood through the pulmonary veins. Each organ gets a supply of blood and this is because each organ has an arterial and venous. “The systemic circulation comprises all the blood vessels not involved in the
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.
Arteries: carry blood away from heart; oxygenated except for pulmonary circulation and umbilical vessels of fetus
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.
I am going to show the similarities and differences of circulatory system of human and echinoderm. To begin with, I am going to write about the circulatory system of human. There are two types of circulation in circulatory system. First of all, pulmonary circulation is the part of the circulation, which carries oxygen depleted blood away from the heart, to lungs, and back to the heart. At first, in process of this circulation oxygen-depleted blood enters right atrium, and the blood pumped into the right ventricle. Then, the blood pumped to the pulmonary valve and goes into the pulmonary artery, and pulmonary artery separated into both right and left pulmonary arteries, which travel to each lung. At the lungs, the blood moves through capillary beds, which is the process that eliminating the carbon dioxide and adding oxygen to the blood. The oxygenated blood then leaves the lungs and goes back to the left atrium, and then blood flows to the left ventricle. From the left ventricle, the blood pumps to the aorta, which is delivering oxygenated blood to the whole body. Secondly, the systemic circulation is that carries oxygenated blood from the heart and to other parts of the body. First, in the process of systemic circulation, oxygenated blood from the lungs moves to left atrium, and then the blood pumps to the left ventricle. Then blood pumps to the aorta, and waste and carbon dioxide
Discuss the different types of blood vessels. Include the different layers composing blood vessels (remember to include tissue types) in your discussion.
The hearts function as a double pump that serves two circulations. The pulmonary pump in the right side of heart is provided for the gas exchange in the body, and the systemic circulation in the left side provides the functional blood supply to all body tissues. The functional blood to the heart is provided by the coronary arteries. Right coronary artery supplies the heart through the posterior interventricular and marginal artery branches; and the left coronary artery supplies the heart via anterior interventricular artery and the circumflex artery. The myocardium is drained by great, small, and middle cardiac veins which
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
1 When the ventricle contracts, the oxygenated blood is taken to the carotid arteries (to the head), and deoxygenated blood is taken to the pulmocutanoeus arteries (to the skin and lungs where fresh oxygen can be picked up).2 In systematic circulation of a human, arteries pick up oxygen-rich blood from the heart and transport it to the body tissues. During this process oxygen is diffused into the cells and carbon dioxide is also diffused from the cells into the blood. In pulmonary circulation, deoxygenated blood is carried from the heart to the lungs and oxygenated blood from the lungs is returned to the heart.3 The 4 chambered heart of a human has the advantage over simpler structures because it allows us to send our deoxygenated blood to the lungs and our oxygenated blood to the rest of the body without having to mix the two. 4 Because of a human’s size and complexity, we need a more efficient circulation system and that is why a 4 chambered heart works best for us, while a 3 chambered heart works best for frogs because they are much smaller and more simple than humans.
Cardiovascular or circulation system is responsible transportation of hormones, supplying nutrients and oxygen demands of tissues and also waste removal (8). Pulmonary circulation replenishes blood with oxygen and eliminates carbon dioxide within lungs, and systemic circulation delivers blood to all other parts of the body. All systemic circulation begins via aorta, the first blood vessel of the systemic circulation and the largest artery of the body. All arteries are exposed to high blood pressure or stress to vessels, and the aorta, being the initial point for entire circulatory pressure gradient, has the highest intravascular pressure. Therefore, the aortic wall is designed to resist high stress
The oxygenated blood is pumped from the left ventricle to the aortal artery through the aortic valve. The oxygenated blood is transported around the body.
The systemic circuit channels blood from the heart to the rest of the body, excluding the lungs, via arteries and back to the heart via veins. In the abdominal cavity, the dorsal aorta branches into arteries that provide blood to the abdominal organs, the legs, and the tail. In the fetal pig, the dorsal aorta branches into two umbilical arteries that lead to the placenta. The blood from the organs, legs, and tail is eventually carried by veins to the caudal vena cava, which carries the blood to the heart.
To reach the body, the oxygen filled blood has to travel through the arteries. The arteries are
The fetus obtains blood(with or without oxygen) from the mother ' placenta via two arteries and one vein, referred to them as the umbilical arteries and vein. The deoxygenated blood travels from fetus 's right atrium into the right ventricle, then bypassing the fetus 's lungs into the ductus arteriosus. The ductus arteriosus sends the deoxygenated blood in the lower half of the fetal body, and at the same time deoxygenated blood also comes from the ascending aorta. This allows for the deoxygenated blood to leave the fetus through the umbilical arteries and get back to the placenta to pick up oxygen. After picking up oxygen from the mother 's placenta and through the umbilical vein, the oxygenated bloods passes through the fetal liver into the right side of the heart. Inside the heart, the oxygenated blood enters the right atrium into the left atrium, passing through a hole that closes as the baby is born, called the patent foreman ovale. This opening, as mentioned earlier, leads to the left atrium from the right atrium where oxygenated blood has arrived from the placenta via the umbilical vein. After the left atrium, comes the left ventricle where oxygenated blood is pushed out through the aorta into the brain where most oxygen is needed. After the distribution of oxygenated blood throughout the fetal body, deoxygenated blood enters the right atrium and the process starts all over, starting at the right atrium, then to the right ventricle and through the ductus
has to work harder pumping blood to the rest of the body. Blood in our
