associated with heart failure and inflammation, although the role of dystrphin in the heart is not understood as well as its role in the skeletal muscles. It has…

Without the heart, you wouldn't be able to basically live at all. The heart pumps blood through the body’s cardiovascular system. The blood gives oxygen and nutrients to the organs and tissues in the body and gives carbon dioxide to the lungs. We need the heart to survive and have a working cardiovascular system. The heart has four main parts: the left ventricle,the right ventricle, the left atrium, and the right atrium. A wall of muscle called the septum separates them. Oxygen-rich blood from…

The heart is considered the “engine of life” through its ability to rhythmically pump oxygen rich blood throughout the body to supply life. Unfortunately, this vital organ is vulnerable to damage through actions of everyday life ranging from smoking, diet, physical inactivity, and consumption of alcohol. Damage to the heart results in heart disease, also known as cardiovascular disease. Because of the vast complexity of the heart, heart disease branches off into various categories including…

are 78 organs in the human body in total, 12 organ systems, and 5 organs that are vital to our existence. Although the heart comes in at a close second to the most essential organ in our body (the brain), the role that it plays in or life is why it lands itself on the list of vital organs. So, what makes the heart so important to our survival? Located between the lungs and the middle of the chest the heart is no bigger than the size of a human fist. The main job of the heart is pump blood to all…

The heart is one of the strongest muscles in the human body. It is mostly made up of cardiac muscle, which causes the contractions of the heart, or heartbeat. The cardiac muscle works constantly to pump blood throughout the body and is one of the three major types of muscle. The cells in the heart are closely connected so that they all beat at the same time, and they form the thick middle layer of the heart, in between the outer epicardium and the inner endocardium layers. There are two main…

The heart is one of the busiest organs in the body. It pumps liters of blood non-stop during an animals's entire live, and any damage to its physical condition tends to be fatal. Myocardial infarctions are common and come in varying levels of severity. At their worst, they cause irreversible damage to the heart's tissue, jeopardizing the whole machinery. Currently, there is no way to restore lost heart function after a devastating heart attack in humans because the damaged tissue cannot be…

Humans and other mammals have a Diving Response, which can be also known as ‘The Mammalian Dive Response/Reflex. The Diving reflex consists of set of reflexes that are activated when our face is cooled or if we hold our breath. This is a clever psychological mechanism because it enables our bodies to manage and to tolerate a lower level of oxygen in an environment that we do not normally face every day. There are three main changes that occur in our body when our Dive reflex triggers;…

injury. The organs that can be donated are; hearts, lungs, kidneys, pancreas, lungs, liver, and intestine which must be used within 4-6 hours after removal depending on the organ. Most donated organs are from those who have previously passed, but living donors can donate as well. Living donors can donate a kidney or part of pancreas, lung, liver, or intestine. Tissues can also be donated, they can donate; corneas, ski, tendons, cartilages, bones, and heart valves which can be stored in tissues…
