Question

With the help of a labelled diagram, trace and explain the path of blood circulation in the human body.

Answer 1

Blood circulation in human body:



Human heart is divided into four chambers: the upper two are called auricles and the lower two are called ventricles. The right auricle receives deoxygenated blood from various body parts, from where it reaches the right ventricle. The right ventricle pumps blood to the lungs, where oxygen is mixed in it. From the lungs, the blood enters the left auricle and then to the left ventricle, from where it is pumped to different parts of the body.
