The heart is a muscle whose primary purpose is to constantly pump blood through the circulatory system. The heart is placed behind the sternum and midway between the lungs. One of the several components and functions of the heart is the apex.
The apex is located above the diaphragm and is the lowest point of the heart. The heart’s apex points to the left side of the body. When the heart beats, this portion of the muscle hits the chest wall, which can be felt by touching the left side of the chest. This is called the peak beat.
Left ventricle constitutes the apex. The left ventricle transports the blood that is pumped into it to the aortic valve, the aortic arch, and the rest of the body. This is a perpetual cycle.
What Are the Major Heart Structures?
There are four chambers that make up the heart’s major structures. The left ventricle, the left atrium, the right ventricle, and the right atrium comprise these chambers. Other components, including coronary arteries, nerve tissue, and the pericardium, contribute to the heart’s functionality.
The bigger left half of the heart regulates blood flow throughout the rest of the body. The smaller right side of the heart is responsible for providing blood flow to the lungs.
The left ventricle has already been described, but there are a few additional details to consider. This chamber of the heart influences our blood pressure. When measuring pressure, the rapid contractions of the left ventricle are utilised. This is the heart’s strongest chamber.
This is the Left Atrium
After passing through the left atrium, blood flows into the left ventricle. The oxygenated blood that is pumped into the left atrium comes from the lungs.
The right ventricle is located in the lower portion of the right heart chamber. Its primary role is to carry very low-pressure blood to the pulmonary artery, which supplies the lungs. The right atrium sends deoxygenated blood to the right ventricle.
The Ideal Atrium
The systemic veins supply blood to the right atrium, which ultimately delivers it to the right ventricle. The remainder of the body supplies the right atrium with deoxygenated blood.
One coronary artery pumps blood to the left side of the heart, while the other pumps blood to the right side. The aorta gives rise to these arteries.
The pericardium serves as the heart’s defender. It is a thin sac that envelops and supports the heart. Its defensive characteristics do not end there. It also lubricates the beating heart to protect it from tissue friction. The pericardium prevents the heart from receiving an excessive amount of blood and protects it from infection that could spread from other organs.
