Talk:Regional function of the heart

Adaptations of mammalian heart to its function:

Mammalian heart is made up of cardiac muscles which is known for its continuous rhythmic action to pump blood without fatigue. Heart is located in the thoracic region of the body which protects it from injury. Interconnected network fiber allows the blood to reach all walls of the heart. Muscular nature of the heart and its systemic circulation ensures the blood travels long distances in the body. Walls of auricles are slightly thinner than the ventricles, it creates high pressure to circulate blood to long distance. Mixing of oxygenated and deoxygenated blood is prevented through the specialized structure of the heart called the longitudinal septum, it divides the heart into two halves. Pericardium layer protects the heart from shocks, maintains its position, and prohibits overdilation, and pericardial fluid prevents friction between two pericardial layers. Natural pacemaker is present in the heart that is the sinoatrial node, these nodes regulate the heartbeat and contraction coupling of the heart.
