Answer:

Right side of the heart

Course of blood circulation through the heart?

AnSWer:-

Deoxygenated blood from all parts of the body lungs and heart enter the right auricle through venacavae. Blood from heart also enters the right auricle through coronary sinus . oxygenated blood from the lungs enter left auricle through the pulmonary veins. The two auricle expand while receiving blood through veins. The two auricles then simultaneously and the blood from auricle is forced into the corresponding ventricle. At the same time the ventricles also expand and received from the auricle. The expansion stage of heart is called diastole. Thee two ventricles then contract simultaneously driving the blood through pulmonary artery and aorta respectively. This contraction part of the heart is called systole. systole is the phase of construction of heart and diastole is the phase of relaxation of heart. The contraction and the relaxation of heart occur in a cyclic way., called cardiac cycle which takes 0.8 seconds to complete.
