Process of the Human Heart
The human heart has four chambers, the right atrium, left atrium, left ventricle, and right ventricle. The human heart has a ton of amazing features. The normal heart rate for adults is 120/80. The human heart weighs twelve ounces and beats at seventy-two beats per minute it is the size of a human fist. Its blood flow has many functions and is extremely vital to our bodies. We would not be able to survive without our heart. I will talk about the functions of our heart and the blood flow of our heart. I will go in detail to let you know things you probably have never heard. Our heart, its four chambers, and blood flow are very interesting and vital to our well-being. Many things can ruin the process of the heart and the way that it works. I will talk about all of the ways that ruin it and I will cover the valves of the heart as well, which are important to the blood flow of the heart.
The human heart has two ventricles and two atria making up four chambers. The heart includes the atria and ventricles. The left atrium and the left ventricle make up the left side of the heart and the right atrium and right ventricle make up the right side of the heart. Each side is important but the left ventricle and left atrium is the most important, and I will tell you why. The left ventricle receives blood from the left atrium and pumps into the aorta. The aorta pumps oxygenated blood to the rest of the body. If someone shot you in your left ventricle, you would most certainly die. That is why it is the most important. It pumps blood to the rest of your body. The right ventricle is important too. The right ventricle receives blood from the right atrium and pumps blood to the pulmonary artery. The pulmonary artery has two sides that branch off and into the lungs, which contain deoxygenated blood that picks up oxygen and return it back to the heart. The heart also has three layers, which protect it.
Three layers protect our heart. The pericardium is the outer layer, the pericardium is a sac that encases the heart and protects the heart. It holds it inside the chest. Between the outer layer is the inner layer and it shoots pericardial fluid. It lubricates the heart during contractions of the lungs and diaphragm. The heart's outer wall consists of three layers. The outer layer is epicardium. The middle layer is the myocardium. It contains the muscle that contracts. The inner layer is what connects the blood. The heart also has many valves. The valves help with the blood flow process and distribution of blood to the body.
The tricuspid valve is the first in the heart. It is one of two AV valves. It is made up of three parts that work together which start the blood flow. Attached to tiny muscles there are things called the papillary muscles, which strengthen the...
