Human heart

because of many different factors. Heart muscle needs blood rich in oxygen to function and pump more blood throughout the circulatory system. If the blood does not carry enough oxygen, the veins will carry it away. Blood can only be delivered when the heart is relaxed; because once they contract they become narrow. These arteries are structured differently as opposed to many of the other arteries in the human body. The coronary arteries are bound on the outside of the heart walls and have…

Muscular System The human body is composed of 640 to 850 muscles each having a different function in helping the muscular system operate. The main function of the muscular system is movement. Muscles help provide strength, endurance, and help to keep the body warm. Muscles help keep the body warm by continuously pumping blood out of the heart and by body movement. There are three main categories of muscles in the human body: skeletal, cardiac, and smooth (non-striated) muscles. One…

The heart is the organ that pumps blood through the body. Together with the circulatory system it makes up the cardiovascular system (Anatomy of the Heart, 2015). The heart is oddly shaped, almost oval at the bottom but with a series of veins and arteries at the top and sides. It definitely is not “heart” shaped. It is made up of four chambers consisting of two atria (upper) and two ventricles (lower). These chambers are separated into right and left side by the septum, which is a wall of muscle…

The heart is the most important muscular organ in the human anatomy. It is located in the thoracic cavity medial to the lungs and posterior to the sternum. Its function is to pump the deoxygenated blood within the veins to the lungs for oxygen before pumping it to the rest of the body’s organs. Every cell in the body needs oxygen, without the oxygen, the cells will die. The heart works by following a sequence of electrical signals that cause the muscles in each chamber to contract in a specific…

Social Determinants of Rural Women’s Health for Heart Disease Introduction Heart disease is the leading cause of morbidity and mortality in Australian women (Crouch & Wilson, 2011) and is found to be highest for populations living in remote rural regions of South Australia (SA Atlas, 2015). This paper analyses the patterns and trends in this population group and the different social determinants and lifestyle behaviours that can affect women’s health. Heart disease remains the leading cause…

The subphylum Vertebrata includes all the familiar animals we tend to see everyday, and some rare and unusual ones (O’Neil, 2012). Scientists classify the seven different Vertebrates based on their skeletal system, general environmental adaptation, and reproductive systems. These seven Vertebrates include, Agnatha, Chondrichthyes, Osteichthyes, Amphibia, Reptilia, Aves, and Mammalia. During the lab dissection, the class dissected organism from only four of these classes. First, we dissected the…

dead until his heart stops beating. A machine inflates and deflates his lungs, however his heart continues to beat on its own thanks to a mix of intravenous drugs and adrenaline. The doctors say they have done all they can to save his life. Thesis: . The parents of the boy believe that a person is not dead until the heart and lungs stop functioning all together. Because of this, they wish for the hospital to continue giving medications and keep him on life support until his heart and lungs are…

Ella is diagnosed with cholelithiasis. 1. What is cholelithiasis? Choleithiasis is when the gallbladder becomes inflamed. In most cases it is caused by gallstones that form from bile collected in the gallbladder. Stones can consist of one large stone or several small stones. 2. Explain where the organ of diagnosis is, using the terminology of body organization from chapter 1. Be as detailed in your description as possible. The gallbladder is located in the right upper quadrant It is placed…

Heart failure is one of the leading causes in death among the human health system. Scientist is constantly finding ways to keep the cardiovascular system healthy so this casualty can be reduced. In order to do that, a solution has to be put in place to keep the cardiovascular system regulated. This means knowing how the heart functions and how to keep it working at a sustainable level so problems can be prevented. The cardiovascular system works on a homeostasis system. This is where the…

States. Each year approximately 600,000 people die from these heart related diseases. Cardiovascular disease is something that can be acquired at birth or over a period of time due to genetics or lifestyle. There hundreds of different types of cardiovascular disease. Cardiovascular disease can be detected through a series of blood test, blood pressure, or even an electrocardiograph. Electrocardiographs record the electrical activity of the heart. The main purpose of this essay is to inform the…
