Heart

Last crawled date: 3 years, 9 months ago

The human heart consists of the two left and right upper chambers or atrium, and two left and right lower chambers or the ventricles. The heart is vital to human life, by pumping oxygen rich blood to every cell and oxygen poor blood to the lungs, to be exhaled. #artery #blood #body #heart #homonid #human #mammal #muscle #organ #part #red #sketchycat #tissue #vein
