the heart is a four-chambered hollow muscle located in the thoracic cavity
it consists of two small receiving chambers, the atria(auricles) and two larger pumping chambers, the auricles
the left ventricles is the most powerful and has the thickest walls
this is because it is the chamber which pumps blood throughout the body
each time it contracts, blood is forced out into the elastic arteries(aorta)
blood moves on to the capillaries
from capillaries blood moves to veins and back to the heart through the vena cava
from vena cava it enters into right auricle which contracts and pumps blood into the right ventricle
right ventricle pumps blood into the lungs through the pulmonary artery
blood releases carbon IV oxide to lungs and picks oxygen then returns to left auricle
left auricle pumps blood into left ventricle
left ventricle then pumps blood into the aorta and into arteries, starting the process all over again
both auricles contract simultaneously while both
