Anatomy and Physiology of the Heart The heart itself is made up of 4 chambers, 2 atria and 2 ventricles.
De oxygenated blood returns to the right side of the heart via the venous circulation. It is pumped into the right ventricle and then to the lungs where carbon dioxide is released louis vuitton bags in italy and oxygen is absorbed. The oxygenated blood then travels back to the left side of the heart into the left atria, then into the left ventricle from where it is pumped into the aorta and arterial circulation. The pressure created in the arteries by the contraction of the left ventricle is the systolic blood pressure. Once the left ventricle has fully contracted it begins to relax and refill with blood from the left atria. The pressure in the arteries falls whilst louis vuitton purses 2015 the ventricle refills. This is the diastolic blood pressure. The atrio ventricular septum completely separates the 2 sides of the louis vuitton alma for sale heart.
