HUMAN HEART Meaning and
Definition
-
The human heart is a vital organ located in the chest cavity, specifically in the middle mediastinum. It is a muscular organ responsible for pumping and circulating blood throughout the body, providing oxygen and nutrients to every cell and removing waste products. In essence, it acts as the central pump of the circulatory system.
The human heart is roughly the size of a fist, weighing between 250 and 350 grams in adults. It consists of four chambers – two atria and two ventricles – which are separated by a muscular wall known as the septum. The right side of the heart receives oxygen-depleted blood from the body through the superior and inferior vena cava, while the left side receives oxygen-rich blood from the lungs through the pulmonary veins.
Through rhythmic contractions, or heartbeats, the heart pumps the blood in a continuous circuit. It contracts to pump blood out into the arteries during systole and relaxes during diastole to allow for blood to flow back into the heart. This perpetual function ensures adequate oxygenation and nourishment to all organs, tissues, and cells within the body.
While its primary purpose is to maintain blood circulation, the human heart also holds emotional and metaphorical significance. It is often associated with feelings of love, compassion, and empathy, and serves as a symbol of deep emotions and the core of human existence.
