Last time we talked about the importance of blood and the process of blood clotting. Now we are going to take a look at blood flow through the heart. This includes two pathways: the pulmonary circuit and the systemic circuit. The pulmonary circuit circulates blood through the heart and into the lungs. The systemic circuit circulates blood through the heart only. The pulmonary circuit starts at eh right atrium, goes through the tricuspid valve, and into the right ventricle. From here the blood goes through the pulmonary semilunar valve and through the pulmonary trunk into the right and left pulmonary arteries. Then the blood reaches the lungs. They systemic circuit starts in the left atrium, goes through the bicuspid valve, and into the left ventricle. From there the blood goes through the aortic semilunar valve and into the aorta.
The blood flow to the heart is an important subject for me to understand because of my mother. Just recently she was in the hospital because the blood was pumping faster in the atrium then in the ventricle. This gave her a "flutter" in her chest, also known as atrial fibrillation.
