A wall, called the septum, separates the right atrium and right ventricle, from the left atrium and left ventricle.Blood flows through the heart in the following manner: The right atrium receives oxygen-poor blood from the body, and then pumps the blood through the tricuspid valve and into the right ventricle. The impulse spreads through the heart in a very organized manner, so that the atria contract first, followed by the ventricles.The electrical impulse proceeds in the following manner: The electrical impulse originates at the sinoatrial (SA) node, which is located in the wall of the right atrium

http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2394690/ Competition: low
(5) The most significant difference between the two forms of heart failure is the difference in LV geometry and LV function; systolic heart failure is characterized by LV dilatation, eccentric LV hypertrophy, and abnormal systolic and diastolic function, whereas diastolic heart failure is characterized by concentric LV hypertrophy, a normal EF and abnormal diastolic function. The degree of diastolic dysfunction helps determine how you distribute your blood volume If you have trouble filling the left, ventricle, you are prone to inappropriately distributing you blood volume into your lungs, so avoidance of increases in intravascular volume is very important.Luke, Cincinnati: I have been very unimpressed with the value of ejection fraction in giving prognosis in heart failure, which is all over the map

The closure of the mitral valve prevents blood from returning to the left atrium, and the opening of the aortic valve allows the blood to flow into the aorta and from there throughout the body.

Ventricular contraction: Right Side:blood leaves the heart through the pulmonic valve, into the pulmonary artery and to the lungs.Left Side:blood leaves the heart through the aortic valve, into the aorta and to the body.This pattern is repeated over and over, causing blood to flow continuously to the heart, lungs and body.

These veins are the largest veins in your body.After your body's organs and tissues have used the oxygen in your blood, the vena cavae carry the oxygen-poor blood back to the right atrium of your heart.The superior vena cava carries oxygen-poor blood from the upper parts of your body, including your head, chest, arms, and neck.
