The heart functions to take deoxygenated blood from the body and pump it to the lungs to re-oxygenate it‚ to pump it back through the body. Without this system‚ body tissues wouldn’t get oxygen and therefore not function and the person would not survive. The function of the left side of the heart is to take oxygenated blood from the lungs and pump it out to and through the rest of the body. This is the systemic circulation of the heart. With every body system there are homeostatic imbalances and
