The heart is the first organ to form and become functional, emphasizing the importance of transport of material to and from the developing infant. The heart has two upper chambers—the left and right atriums—and two larger lower chambers, the left and right ventricles. This prevents blood from flowing backward into the atria while the ventricle contracts. This system controls the rate and rhythm of the heartbeat. Here the signal slows down slightly, allowing the ventricles time to finish filling with blood. This is how you can calculate it: Normal heart anatomy and physiology need the atria and ventricles to work sequentially, contracting and relaxing to pump blood out of the heart and then to let the chambers refill. Normal Blood Sugar Levels (Ranges) In Adults with Diabetes, The heart is an amazing organ. The blood then passes through the tricuspid valve into the right ventricle.
