The esophagus and the spine lie further behind the heart. II. FUNCTIONS OF THE HEART The role of circulation is to: 1. Continuously deliver oxygen‚ nutrients‚ hormones‚ and antibodies to organs‚ tissues and cells throughout the body in response to varying tissue demands. 2.

blood not being able to circulate from the body and lungs back to the heart‚ causing fluid to leak from capillary blood vessels. Heart failure is most commonly caused by a weakness of the muscle of the left ventricle‚ which leads to inadequate circulation. Congestive heart failure‚ if left untreated‚ disrupts the homeostasis in the human body‚ causing other problems. Heart failure doesn’t mean your heart stops pumping‚ it means your heart isn’t meeting your body’s need for blood and oxygen. When

Accordingly‚ the organs function well and the person feels healthy. Thus‚ exercising increases out well-being and total fitness. On the other hand‚ people who lead sedentary lives do not exercise and prone to diseases such as hypertension‚ diabetes and coronary diseases. Thus to avoid these silent killers‚ we should exercise. Sports can help us reduce weight. Obesity

compensate for its lack of pumping ability by becoming hypertrophic. This causes the muscle in the heart’s wall to thicken thus improving the hearts pumping ability. (Cadwallader p. 1142). The heart may also increase heart rate to improve output and circulation. The kidneys eventually join in by retaining salt and water to increase volume‚ but this extra fluid can cause edema and further complicate the situation. (Cadwallader p. 1142). Unfortunately‚

some exceptions: the Pulmonary veins‚ the Pulmonary arteries and the capillaries. The body also has two types of circulations: The Pulmonary circulation takes deoxygenated blood from the heart to the lungs‚ picks up oxygen and goes back to the heart. The oxygenated blood is then transported to the rest of the body before returning to the heart via the Systemic circulation. During this process blood goes to the stomach‚ intestines‚ spleen and pancreas‚ these have their own set of blood vessels
