Today in Science class we learned about the Circulatory System. We mainly focused on the heart for today. The blood has a certain path through the different parts and valves. It starts in the body and is passed through the vena cava and ends up in the right atrium and then passes through the Tricuspid valve and enters the right ventricle. Then it is pushed through the pulmonary valve and pumped through the pulmonary artery. The blood then goes to the lungs to exchange the carbon dioxide for oxygen rich blood. Next it flows into the left atrium and pumped through the mitral valve to the left ventricle. After this, it goes into the aortic valve into the aorta and is then branched out to all parts of the body. This cycle repeats many times throughout the day.
