Introduction
One of the most important organs in the human body is the heart. It works continuously from
the moment a person is born until death. Pumping blood throughout the body, supplying oxygen
and nutrients to every cell, and removing waste products like carbon dioxide are all functions of
the heart. Without the heart, the body cannot survive because all organs depend on a constant
supply of oxygen-rich blood.
The heart is a muscular organ that pumps blood around the body. In a healthy adult, it beats
between 60 and 100 times per minute, and in children, it beats even faster. On average, the
human heart beats about 100,000 times per day and pumps nearly 7,000–8,000 liters of blood
daily. This demonstrates how powerful and laborious this tiny organ is. We will go over the
anatomy, location, functioning, blood circulation, parts, functions, and most common diseases of
the human heart in detail in this assignment. Size and Position of the Heart In the chest cavity,
slightly to the left of the body, is where the heart is. It is behind the sternum (breastbone),
between the two lungs. It is protected by the rib cage.
The human heart is roughly the same size as a closed fist. In adults, it weighs about 250–350
grams. Despite its small size, it accomplishes a tremendously significant and significant task.
