Please help!! i need to trace a drop of blood through the heart and cant remember it...?

Question

I have a final on wed. and i need to know the pathway of blood through the heart. I am having trouble remembering it. Is there anyone who knows a pnemonic or some website or anything that is helpful? Please!! Thank you!! PLEASE

Answer 1

Venous blood returns to the heart through the inferior and superior vena cavae into the right atrium, through the tricuspid valve and down into the right ventricle. From there it goes through the pulmonary arteries to the lungs. It returns to the heart through the pulmonary veins and into the left atrium, through the mitral valve and into the left ventricle, out through the aortic valve and into the aorta. Let's see if we can come with a pneumonic using this.

Red Ants Try Red Veggies (Rt. atrium-Tricuspid valve-Rt. ventricle)

Pink Ants Love them (Pulmonary artery-Lungs).

Purple Veggies for Lovely Ants Might be Less Valuable than All Veggies for Ants (Pulmonary vein-Lt. ventricle-Mitral valve-Lt. ventricle-Aortic valve-Aorta).

Another way to remember is Upper Right, Lower Right, to the Lungs, out the Lungs, Upper Left, Lower Left and out the heart.

There may be a better, much better one out there. Sorry, I never had a problem with this and so never had to learn any special tricks.

Answer 2

"Oxygen-poor blood enters the right atrium of the heart (via veins called the inferior vena cava and the superior vena cava). The blood is then pumped into the right ventricle and then through the pulmonary artery to the lungs, where the blood is enriched with oxygen (and loses carbon dioxide). The oxygen-rich (oxygenated) blood is then carried back to the left atrium of the heart via the pulmonary vein. The blood is then pumped to the left ventricle, then the blood is pumped through the aorta and to the rest of the body." - See citation below.

So, the order is Right Atrium, Right Ventricle, (lungs), Left Atrium, Left Ventricle. Can't come up with a specific mnemonic, but all you have to do is remember upper right, lower right, upper left, lower left (atria are at the top, ventricles are at the bottom).

Answer 3

Pathway of Blood:
PATHWAY OF BLOOD THROUGH THE HEART


While it is convenient to describe the flow of blood through the right side of the heart and then through the left side, it is important to realize that both atria contract at the same time and that both ventricles contract at the same time.


The heart works as two pumps, one on the right and one on the left that work simultaneously. The right pump pumps the blood to the lungs or the pulmonary circulation at the same time that the left pump pumps blood to the rest of the body or the systemic circulation.


Venous blood from systemic circulation(deoxygenated) enters the right atrium through the superior and inferior vena cava. The blood flows through the tricuspid valve and into the right ventricle. From the right ventricle it passes through the pulmonary semilunar valve into the pulmonary trunk, then into the pulmonary arteries, which carry the blood to the lungs.


In the lungs, the blood releases carbon dioxide and picks up a new supply of oxygen: then the pulmonary veins carry the blood to the left atrium.


From the left atrium, it flows through the bicuspid or mitral valve into the left ventricle and then through the aortic semilunar valve and into the ascending aorta. Oxygen rich blood flowing through the aorta is distributed to all parts of the body through systemic circulation.


See...this is much easier than you thought!!!!!!


BLOOD SUPPLY TO THE MYOCARDIUM


The myocardium of the heart wall is working muscle that needs a continuous supply of oxygen and nutrients to function with efficiency. Unlike skeletal muscle tissue, cardiac muscle tissue cannot build up an oxygen debt to be repaid at a later date. It needs a continuous supply or it simply dies. For this reason, cardiac muscle has an extensive network of vessels taking oxygen to the contracting cells and to remove waste products.


The right and left coronary arteries, branching off the ascending aorta, supply blood to the walls of the myocardium.


Blood flow through the coronary arteries is greatest when the myocardium is relaxed. When the ventricles contract, they compress the arteries, which reduces the flow.


Angina pectoris is chest pain that results when the heart muscle demand for oxygen exceeds the oxygen supply. Nitroglycerin is sometimes used in the treatment of angina pectoris because it dilates blood vessels , so that the patient is less likely to develop a myocardial oxygen deficit.


If a branch of coronary artery becomes blocked, blood supply to that region of the heart is cut off and the muscle cells in that area die from lack of oxygen. This is a myocardial infarction (MI). The extent of the damage and the chances of recovery depend on the location of the blockage and the length of time that elapses before medical intervention occurs.


Blood from the capillaries in the myocardium enters the cardiac veins, which drain into the coronary sinus. From there it enters the right atrium.

Answer 4

vena cava to the right atrium to the triscupid valve to the right ventricle to the pulmonary artery to the lung back through the pulmonary vein to the left atrium threw the micpid (cant spell worth a poop) to the left ventricle to the aortic valve to aorta!!!
