Adaptations of the Heart

Describe the structural adaptations of the mammalian heart to its functions.

The organ of the circulatory system made of cardiac muscles that pump blood to the whole part of the body without any rest is referred to as the heart. The mammalian heart consists of four-chamber which are right and left atria and right and left ventricles.

Answer and Explanation:
Adaptations of mammalian heart to its function:

Mammalian heart is made up of cardiac muscle 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 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 to travel 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.
