The human heart is an organ that transports blood through the circulatory system by its vessels, providing oxygen and nutrition to the tissues while also eliminating carbon dioxide and other pollutants from the body. Your circulatory system, which is made up of a network of blood arteries that circulates blood throughout your body, is led by your heart. It also works in conjunction with other physiological systems to maintain healthy blood pressure and heart rate. Your heart’s performance is influenced by your genetic history, individual health history, and lifestyle. The human heart is in the middle of the chest, just to the left side of the sternum (breastbone). It is enclosed in the pericardium, a double-walled sac that is seated between your lungs. The pericardium protects and anchors the heart inside the chest. Between the exterior layer, the parietal pericardium, and the internal layer, the serous pericardium, pericardial effusion works as a lubricant. The effusion lubricates the heart during contractions and motions of the lung and diaphragm. 

The organ is divided into chambers that accept and distribute oxygen-depleted or oxygen-rich blood depending on the blood condition. These chambers are connected to veins and arteries, which aid in the same purpose. Because all of the heart’s components work together toward a single goal, the heart is extremely efficient at pumping blood. A healthy adult heart can beat at a pace of three cardiac sets for every minute, or 72 beats each minute; however, this rate varies for youngsters whose heartbeats are usually substantially quicker. The human heart is an organ that is separated into two distinct pumping stations, the right side and the left side. The right side of your heart takes oxygen-depleted blood from your vessels and circulates it to your lungs, where it collects oxygen and expels carbon dioxide. The left side of your heart takes oxygen-rich blood from your lungs and distributes it to other parts of the body via your arteries. 

The human heart is divided into four chambers. Two top chambers, the atria, and two bottom chambers, the ventricles, make up the human heart. The “right heart” is made up of the right atrium and right ventricle, whereas the “left heart” is made up of the left atrium and left ventricle. The septum is a muscular wall that divides the two chambers of the heart. The exterior wall of the heart is made up of three layers, which are as follows: The inner surface of the pericardium is formed by the outermost wall layer, known as the epicardium. The myocardium, which is the central layer of the heart, includes the tissue that contracts the heart. The inner layer of the heart, termed the endocardium, borders the chambers. The processes that allow blood to circulate all across the body and back to the heart make the cardiac architecture more complicated.  The human heart is an organ that has veins and arteries, two diverse kinds of vessels that aid in this iterative process. Veins return oxygen-free blood to the heart, whereas arteries carry oxygen-rich blood out of the heart to other parts of the body.

Your heart valves act as doors connecting your heart chambers. They open and shut to circulate blood. A typical 24-hour period sees a person’s heartbeat somewhere between 60 and 80 times per minute. In the human body, there are roughly 97,000 kilometres of blood vessels, and your heart pumps approximately 6.8 litres of blood each minute through them. Consider your body a computer. As a hard drive and processor, the brain holds all applications, data, and memory. It also executes these activities, routing them via the system. But the human heart is an organ that works like a power supply. Nothing else functions without power. Every cell in your body gets energy from your heart’s electrical pulses.  The trouble is, if that electricity goes out, everything starts dying. They require continual blood and oxygen delivery. Both processes begin when the heart stops. Now, the body stores some oxygen.  But the blood must flow. Consequently, in the event of cardiac arrest or a heart attack, it’s more critical to maintain the heart pumping by doing chest compressions than giving mouth to mouth breathing. The body commences perishing when the heart ceases pounding. CPR chest compressions can be used to maintain the heart pumping until the emergency aid arrives. This has the potential to mean the difference between life and death. With adequate CPR training, almost anybody can execute that life-saving move.
