Complexity of the heart
From a young age we are taught what the heart is from pictures, books and even signs that the heart is the color red, shaped with two humps at top and comes to a point on the end. On the daily we see commercials like cheerios explain to us how important it is to take care of our heart. Yet in all actuality the heart is a complex organ that not all are fully aware of and if were to actually start explaining to children that the heart is actually spear shaped and does a lot more then pump I feel that a child would be amazed and confused maybe even grossed out all at once. The heart is a vital part of what makes us as humans and even
The heart has more dimensions and features and is not as flat as were taught at a young age. The heart a muscular organ about the size of a fist, located just behind and slightly left of the breastbone. The heart pumps blood through the network of arteries and veins called the cardiovascular system. The heart has four chambers; the left and right atrium, left and right ventricle and the coronary Arteries that run along the surface of the heart and provide oxygen-rich blood to the heart muscle (The Heart 2014).
The primary function of the human heart is an organ that pumps blood throughout the body via the circulatory system, supplying oxygen and nutrients to the tissues and removing carbon dioxide and other wastes (Lewis, T. 2015). When you restrict the blood flow to a certain area of the body it cause that part of the body to change colors for example tying a rubber band around a finger so it is tight you notice that your finger can go from the normal look to white to blue which is because the blood the heart is pumping it not reaching the area it needs to, to function
An organ is made of several types of tissue and therefore several types of cells. For example, the heart contains muscle tissue that contracts to pump blood, fibrous tissue that makes up the heart valves, and special cells that maintain the rate and rhythm of heartbeats. The eye contains muscle cells that open and close the pupil, clear cells that make up the lens and cornea, cells that produce the fluid within the eye, cells that sense light, and nerve cells that conduct impulses to the brain. Even an organ as apparently simple as the gallbladder contains different types of cells, such as those that form a lining resistant to the irrigative effects of bile, muscle cells that contract to expel bile, and cells that form the fibrous outer wall holding the sac together (Villa-Forte, A.
