The dog's circulatory system is quite similar to that of humans. The heart has four chambers. The two upper chambers are the left and right atria, while the stronger, lower chambers are the right and left ventricles.
There are trillions of good bacteria present in the human body.
After interphase, there are 46 chromosomes present in a human cell.
There are about 3 billion nitrogen base pairs present in one strand of human DNA.
There are two types of muscles which are NOT under your control. They are smooth muscles present in many tubular organs present in your body. Second type is present in heart called as cardiac muscles.
The movement of electrical impulses in the heart coordinates the contraction of its chambers. The impulses initiate the contraction by stimulating the muscle cells, causing them to contract in a coordinated way. This results in the rhythmic pumping action that drives blood flow through the heart and to the rest of the body.

It contains 4 chambers
the human heart contains four chambers and it is the ventricles (the two lower chambers) that do the pumping
The human heart has four chambers connected by valves. We have 2 smaller chambers on the upper half of our heart and two larger chambers on the bottom of our heart. The smaller chambers are called atria; the larger chambers are called ventricles. So we refer to these chambers as right and left atrium, and right and left ventricle.
