What is the sequence of blood flow through the heart and vascular system?

What is the sequence of blood flow through the heart and vascular system?

Here you go: Blood enters through the vena cavae, passes through the right atrium into the right ventricle. The blood then goes out into the lungs and returns via the pulmonary veins to the left atrium. That blood then goes out the left ventricle to the body and returns via the vena cavae. The order of blood vessels is great vessels, arteries, arterioles, capillaries, venules, veins and back to the cavae. ...Read more

Circulation (Definition)

1.Movement to and fro or around something, esp. That of fluid in a closed system. 2.The continuous motion by which the blood travels through all parts of the body under the action of the heart. Compliments ...Read more

When traveling through the heart and blood vessels where is the blood low in oxygen?

When traveling through the heart and blood vessels where is the blood low in oxygen?

Circulation: Blood releases o2 to the tissues and becomes poor in oxygen to travel up to the lungs to capture it in the vessels there. Then it returns to the heart that pumps oxygenated blood to the tissues to be released there and return to the lungs again to get oxygenated. ...Read more

When traveling through the heart and blood vessels where is the blood high in oxygen?

When traveling through the heart and blood vessels where is the blood high in oxygen?

Circulation: Blood releases o2 to the tissues and becomes poor in oxygen to travel up to the lungs to capture it in the vessels there. Then it returns to the heart that pumps oxygenated blood to the tissues to be released there and return to the lungs again to get oxygenated. ...Read more

In coronary bypass surgery which blood vessels supply the wall of the heart with blood?

See below: The Left anterior descending with its branches, diagonals and septal perforators, the left circumflex with its branches, obtuse marginals, and the right coronary artery with its branches, especially the posterior descending and posterolateral branches. ...Read more

Is the blood pressure in the lungs separate from the heart blood pressure?

Is the blood pressure in the lungs separate from the heart blood pressure?

Yes: Oxygen poor venous blood flows to the right side of the heart. It is then pumped into the lungs, and from there goes to the left side of the heart which pumps it into the arteries to the entire body. The commonly measured pressure is the arterial pressure from the lt side of the heart. The pressure in the lungs is from the rt side of the heart, is much lower, and takes an echocardiogram to measure. ...Read more

All deoxygenated blood returning to the heart from the systemic circulation first flows into the:?

All deoxygenated blood returning to the heart from the systemic circulation first flows into the:?

The short and sweet: Blood gets oxy in lungs then thru pulmonary viens goes to left atrium- thru mitral valve to left ventricle- out of heart to rest of body thru the aortic valve. Blood travels to the tissues where oxygen is picked up and used . The deoxygenated blood then goes back to rt side of heart to rt atrium then across tricuspid valve to rt ventricle and thru pulmonary artery to lungs to get oxy. ...Read more

Can the flow rate on a IV line cause atrial fribulation, which in turn weaken the heart muscle, create clots and flood the lungs.

Can the flow rate on a IV line cause atrial fribulation, which in turn weaken the heart  muscle, create clots and flood the lungs.

IV fluid: Fluid is given through an "IV" (a little tube inserted into a vein) for many reasons: to treat dehydration, to give medicines, & to maintain fluid balance when patients aren't drinking. In some patients if too much fluid is given too quickly it can cause problems including with the lungs. For a detailed review of a particular patient problem, ask a doctor through an inbox consult on HealthTap. ...Read more

Does ehlers danlos increase the risk of heart attack caused by vessels and such in the heart collapsing and not letting enough blood through?

Does ehlers danlos increase the risk of heart attack caused by vessels and such in the heart collapsing and not letting enough blood through?

No: Glad to reassure you. It just doesn't. Even Ehlers-Danlos IV, in which the arteries end up very fragile and prone to intractable hemorrhaging, doesn't do this. It just doesn't happen. ...Read more

How is the pulse rate related to heart rate and the flow of blood in someone?

How is the pulse rate related to heart rate and the flow of blood in someone?

Same: Pulse rate and heart rate are the same generally...This occurs when blood is ejected from the left ventricle to the systemic arterial circulation. There are rare instances when a premature beat comes so close ti last beat that a strong pulse is not transmitted but this is rare. ...Read more

Why coarctation of aorta in infantile, cause passes of the blood from pulmonary artery to the aorta through pda?

Why coarctation of aorta in infantile, cause passes of the blood from pulmonary artery to the aorta through pda?

Plumbing!: Blood must get to the body, else the fetus would not survive. The same is true once the baby is born. In utero, blood flows from pulm artery (pa) to aorta (ao) normally. Once born, the blood continues to flow this way so that blood can get to the body. When the PDA closes, the child becomes very sick. ...Read more

Please help docs! where does perfusion occur in the blood flow of the heart?

Please help docs! where does perfusion occur in the blood flow of the heart?

All over!: The left ventricle pumps blood into the aorta. The first branches off the aorta are the left main and right coronary arteries. These arteries have branches that distribute blood all over the heart. These smaller arteries have even smaller branches called arterioles. The arterioles branch into microscopic capillaries. This network is so thorough that every heart muscle cell is close to a capillary. ...Read more

How does the heart in a relaxed state move blood through arteries?

How does the heart in a relaxed state move blood through arteries?

Arteries pump too!: The arteries are lined with muscle, which aid in the movement of blood through the body. The "pulse" one feels is the contraction of these muscles. Additionally, veins, unlike the arteries, have no muscular lining and thus do not pump blood. They move blood through the assistance of the skeletal muscles and valves found in the veins. ...Read more

True?False? Laying on ur back during pregnancy slows the return of blood to the heart which reduces blood flow to the fetus less oxygen less nutrients

True?False? Laying on ur back during pregnancy slows the return of blood to the heart which reduces blood flow to the fetus less oxygen less nutrients

Depends: early in pregnancy lying on your back is fine. Later in the third trimester some women may be advised to lay on their left side to reduce blood pressure or in cases of poor fetal growth. However, for most women lying on your back is compensated with an increase in your pulse and the oxygen level to the baby is fine. So, for some this is true, but in general is false. ...Read more
