Cardiac anatomy

how different individuals respond to exercise, specifically how long they can work and how efficiently they work. We predicted that females who exercise will have a higher relative-VO2, higher a-vO2-difference, higher stroke volume(SV) and higher cardiac output(CO) at their peak work rate; than individuals who do not exercise. In addition, we predict that females who exercise their heart rate(HR) will be lower before and after exercise than in females who do not exercise. These subjects…

Introduction Some people believe that we have only one type of muscle in our bodies that help us with all different types of tasks, however; not only do our bodies have different muscle types, they also contain different muscle fibers that are used for different activities. Skeletal muscle contain three types of muscle fibers: slow twitch, fast twitch oxidative, and fast twitch glycolytic. Most muscles in our bodies have different combinations of these muscle fibers, although our body recruits…

exercise should be as rigorous as is safe for each patient. A medical doctor should probably be the one to determine this and to supervise the exercising in case of emergency or question of ability to perform a certain act. A physical therapist and a cardiac rehabilitation therapist should be consulted as well in order to…

diagnosis of DMD. By the age of 12, the ability to walk may be lost and children will probably need a wheelchair while also skeletal deformities such as scoliosis and lordosis start to appear. In the early teen years, progressive weakness of the cardiac and diaphragm muscles leads to the development of cardiomyopathy and respiratory disorders respectively. Males with DMD usually die at the age of 25 from respiratory infection or chronic cardiomyopathy but there are few individuals who survive…

For instance, cardiac muscle tissues which are only found in the heart are striated with one nucleus per cell. They are involuntary muscles and they have intercalated discs which allow the heart to contract. Like cardiac muscle tissues, skeletal muscle tissues are composed of striated tissues. However, they contain multiple nuclei and are usually connected to either…

The Cardiac Cycle The cardiac cycle is the sequence of events that occur in the heart during one heart beat. It is how the heart operates, and what exactly happens when it contracts and relaxes. The heart is equipped with four chambers and one-way valves that work with precision to pump blood to and from the body. The heart regulates blood volume to support efficient circulation to the cells, tissues, organs, and systems. It provides oxygen and nutrients to the bodies tissue while also…

such as corticosteroids, maximizing blood flow to muscle tissue, and prolonging the development of cardiomyopathy (“Duchenne Muscular Dystrophy”, 2016). Moreover, with the research and an increase in the availability of physical, respiratory, and cardiac treatments, patients with DMD are able to live longer than ever before. The average life expectancy of someone with DMD is currently only 27 years old, but survival into the late 30’s and early 40’s has become more common thanks to treatment…

Introduction: The importance of this research paper is to clarify, discuss and understand the issues that impacts beast meat quality in poultry. The three main issues the poultry industry has been faced with is white striping of breast muscle, woody breast, and deep pectoral myopathy. These issues is not a medical or health issue for humans’ consumptions but, a quality issue of consumption. The white strip of breast muscle is strips parallel to the muscle fiber. It is mostly found in breast…

A Possible Silent Killer On average, two out of every one thousand people have this medical condition (“Aortic Valve Stenosis”). What is this potentially deadly disorder and who does it affect? This disorder is called Aortic Valve Stenosis and it can affect anyone. Aortic Valve Stenosis, also known as AVS, happens when the aortic valve narrows. The narrowing keeps the valve from operating properly by not allowing the valve to fully open. With the aortic valve not working correctly, it causes…
