Birds, like mammals, have a 4-chambered heart (2 atria & 2 ventricles), with complete separation of oxygenated and de-oxygenated blood. The right ventricle pumps blood to the lungs, while the left ventricle pumps blood to the rest of the body.
The fastest measured was a Ruby-throated Hummingbird at 615 beats per minute. The heart rate of Black-capped Chickadee averages 480 beats per minute, or about 8 beats per second (Calder 1968). Think about that as you watch the chickadees and other birds coming and going from your bird feeder!

Answer:
Explanation:
The interventricular septum (IVS, or ventricular septum, or during development septum inferius), is the stout wall separating the lower chambers (the ventricles) of the heart from one another.
The ventricular septum is directed obliquely backward to the right, and curved with the convexity toward the right ventricle; its margins correspond with the anterior and posterior longitudinal sulci.
