Similarities Between The Heart And The Human Body

In Falcon’s report “Heart Disease” he anatomically describes the heart as “a fist sized organ located in the lower left quarter of the chest…[consisting] of four chambers: the right and left atria on top and the right and left ventricles at the bottom” (Falcon). While the heart is one of the smaller organs in the body, it has an enormous and important job to do; deliver nutrient carrying blood to the tissues in the human body. In people with heart disease, the heart is impeded and cannot efficiently deliver nutrients and oxygen to structures such as our muscles or our brain. This is one of the reasons that heart disease is so deadly; when our body structures are deprived of necessary nutrients, they begin to breakdown. The term “heart disease” encompasses a wide variety of

The heart is what keeps the human body running. From the very first time someone presses their head up against their mothers chest or feels their own heart beat, they know that the pulse they feel means something important. It’s the rhythm that lets us keep on living. It’s strange to think that before I read this book, I barely knew anything about this absolutely vital organ in my body. Now, I probably know more history about the human heart than I ever thought I’d know. This book went totally in depth about the history of the human heart, and how modern medicine knows what it knows about this vital organ. It weaves history and information about the heart together in a way that keeps you interested until the last page, which is something I

Heart is associated to cardiovascular system, heart is also known as the blood-pump of the body. It pumps blood through the circulatory system to all parts of the body. The blood carries food and oxygen to the cells and carries

Once in coherence, the dominant voice in between heart-brain connection is always heart. Heart can convince brain, influence it and may be change it but brain hasn’t that strength to convince heart over something. Imagine how adventurous you feel when standing at top of any mountain, that adrenaline in your blood, that extra energy that just pumps up the body, your heart feels like it has achieved everything that moment, that moment is contagious for you and if let’s say there is a paragliding sort of activity, considering a fear of height and taking this risk would you be still trying it?

In cardiac muscle, a single nucleus is located in the middle of each fibre. The brain tissue also has a nucleus which is located in the middle of cell body. The cardiac muscle and brain tissue don’t have the exact same function. The cardiac muscle and the brain tissue don’t work together because the cardiac muscle doesn’t takes any instructions from the brain tissue (Neurones). This means that the cardiac muscle contracts automatically.

The heart is a very abstruse thing. Scientifically, know the differences between a human’s heart and a dog’s heart. They know how many hearts a worm has and how a bacterium has none. Doctors know how to perform surgery on the heart without killing a person while a scientist uses a dead person heart to figure out how to prevent premature death. But other than that, the heart is a mystery. Why does the heart hurt when we lose someone we love? Why does it grow when

This article will explore your heart's anatomy. We'll describe its exterior, including the arteries and veins that supply blood to the muscle. We'll also describe the organ's interior, including the chambers, valves, and blood flow. Lastly, you'll learn how its electrical system helps ensure its proper function.

The heart is controlled by an electrical system of the heart. This electrical system (Figure 1.1) of the heart includes several functions which hold the contraction of the heart muscles. The SA node starts the heartbeat by contracting the upper two chambers of the heart known as atria. This electrical impulse travels through bundle bunches and Purkinje fibers. This pathway of electrical impulse contracts the lower chamber of the heart called as ventricles. From

The heart is one of the main organs of the human body which is responsible for pumping blood throughout the body including the brain and other organs through the circulatory system.

The heart beats faster and works harder when you are active. It beats more slowly and works less hard when you are resting. Your brain sends signals to the heart to meet the needs of your body.

• autorhymicity- The heart is autorhythmic. This means it generates its own rhythmic action potential independent of the nervous system.

This table shows the similarities and differences between the cardiac and skeletal muscle. One of the main similarities is the fact both muscles are categorized as striated muscles. Striations are the main key to identifying the skeletal and cardiac muscle. The striated muscles are attached to the bone of the cells in which they produce all the movement in the body. Another similarity is that they can be electrically conducted because they both contain t-tubules. The t-tubules are the plasma membrane of both muscles. They allow depolarization of the membranes which then penetrate into the cell.

The heart is what keeps all living breathing species alive, animals or humans. If the heart was to shut down but the nervous system continued and was active, it would not matter. The entire body would shut down because once the supplier no longer delivers what is needed; organs will no longer function correctly, therefore causing irreversible damage. Arteries are what carried the rich oxygenated blood from the heart to the rest of the organs throughout the body. The Veins are what bring back the carbon dioxide blood to the heart. It then has to be put through a cycle so that it can be shipped back out. Blood travels from the right atrium through the tricuspid valve, to the right ventricle. From there, it is pumped to the lungs, the oxygen-rich blood goes to the left atrium and then through the mitral valve to the left ventricle where it goes to the aorta to be pumped around the body (Colombo 7). What looks to be a complicated process that would take hours or minutes is actually done in a matter a seconds.

The hearts role is to pump oxygenated blood to every cell in the body by having a continuous beat. Throughout time the heart has created mystery, however current technology has solved most of the mystery, there still remains an enchantment and eagerness to learn more.

In our world organisms occupy a sliding scale of complexity. On one hand we have the single cell organisms, where all necessary functions for their life are carried out within that one cell. At the other extreme we have extremely complex multicellular organisms, of which humans are perhaps the cardinal member. Obviously, with increased capacity comes increased abilities. Complex organisms are able to manipulate their environment to a greater extent then their simpler cousins. While this has a lot of advantages, it also presents interesting biological problems. With the increased complexity multicellular organisms must have systems to deliver nutrients, signaling molecules, and biochemical building blocks to every cell. In
