Heart anatomy is so surprisingly complex for an organ that is only about the size of a human fist. Every good lifetime fitness program that includes reaching your target heart rate requires a healthy heart. Everyone should be aware of the complex anatomy of their heart, the best ways to keep it healthy, the dangers of heart disease and the factors that contribute to heart failure. The anatomy and workings of the heart are essential in understanding both mens health and womens health.
The heart is located in the chest cavum that is just behind the breastbone, between the lungs and superior to the diaphragm. A sac filled with fluid called the pericardium encircles every healthy heart. The blood is pumped away from the heart through arteries and returns to the heart via the veins. The major artery in the anatomy of the heart is called the aorta and the major veins are called the vena cava.
The heart is separated by a partition called a septum into two halves. The halves are then separated into chambers. The upper two chambers of the heart are called the atria while the lower two chambers are called ventricles. The heart has valves that allow blood to flow in only one direction between the chambers of the heart. The wall of the heart is separated into three layers called the endocardium, myocardium and epicardium. Cardiac conduction is the rate at which the heart carries electrical impulses. Heart muscle cells contract spontaneously and are matched by the nodal tissue. Other factors that affect heart rate include body temperature, hormones and exercise.
There are many factors including family history and anatomy defects that determine how healthy a heart can be. Even with a healthy diet and lifestyle, certain factors can cause disease or heart failure. Consult your doctor for more information about heart health and have your concerns addressed.
