Muscle Contraction is part of an organ in the body that is tensive. It may have a process of tensions that may be developed with muscle tissues. Contraction can be a meaning of shortening or long. Muscle Contraction can also produce a muscle cell that is for movement of the body. Myosin and Actin is an interaction protein to Muscle Contraction, it can be changed by shape but not by volume. Skeletal Muscle contraction is produce by heat. The muscles may receive signal from the brain. Once it receives signal it expands or contracts. Skeleton can provide muscle movement and frame work. This kind of muscle can be found attached your bones. Filaments there are only two types of sliding filaments. The Thick Filaments is called “Myofliaments”. Myofliaments produces myosin. Myosin is a protein and can be found in muscle tissue that makes a thick filament. A filament called actin forms a contract with Sarcomeres of skeletal muscle. With the Sarcomere, actin and myosin slides across each other for shortening of a muscle fiber. The thin filaments is called “actin” is a muscle protein. Actin is pulled by Myosin to cause a contact to a muscle. Actin sometimes forms bacteria to use for motility. The Roles of ATP is a shorten term of actin and myosin filament. ATP is a sort of fuel to give to the muscle during contractions; this type of energy is to make the muscle move.…
Right-sided heart failure is a consequence of left ventricular failure. When the fluid pressure increases in the left ventricle, but is too weak to pump the fluid out into the aorta, the fluid regurgitates into the left atrium and subsequently backs up into the lungs. In the same manner, the right ventricle pump deoxygenated blood to the pulmonic vein but is met with great resistance due to congested lungs, thereby pushing the fluid back into the right atrium, and into the vena cava. This backing up of blood causes swelling of the abdomen, legs and ankle.…
“Racism is man’s gravest threat to man- the maximum of hatred for a minimum of reason.” (Abraham J. Heschel, Jewish philosopher). Richard Beynon’s ‘The Shifting Heart’ was first published in 1960, and insightfully explores the impact of racism. It is based on the lives of the Bianchis, an Italian family living in the suburb of Collingwood, during the post World War II immigration boom. As a literary device, symbolism is the representation of a concept through underlying meanings of objects. Beynon portrays the message, ‘racism is a result of intolerance, not the specific races alone,’ through the use of symbolism as well as the various racial attitudes of characters. The set of the play, harmonica and Christmas Tree are all vital in depicting the play’s theme and message. The use of symbolism in ‘The Shifting Heart” strongly highlights the contrasting racial attitudes towards the cultural differences of characters.…

There are three types of muscle tissue—smooth, skeletal, and cardiac. Each has its own distinctive function, and therefore, its own distinctive structure, but all muscles allow movement of some kind.…
Cardiac muscle is essentially limited to the heart, though it extends slightly into the nearby blood vessels. It too, is striated, but it differs from skeletal muscle. As far as the features, the cells are much shorter, so they are called myocytes rather than fibers. Cardiac muscle is considered involuntary because it is not usually under conscious control; it contracts even if all nerve connections to it are severed.…
The muscular system is what is responsible for the way that we move. Without the muscular system, we wouldn't be able to participate in the normal activities that we do today. There are 700 known/named muscles that are attached to the human skeleton. There are three different types of muscle that can be found in the human body. The Visceral muscle which can be found inside organs such as the stomach. This type of muscle is controlled by the unconcious part of the brain. This muscle is also known as the involuntary muscle. Cardiac Muscle is the second type of muscle found in the human body, and you guessed it, you can find cardiac muscle in the heart! Cardiac muscles are responsible for pumping blood throughought the human body. And these muscles…
Congestive Heart Failure can be brought on by many conditions. These conditions include Coronary Artery Disease, Heart Attack, and lastly Cardiomyopathy. Coronary artery disease can develop in humans after years over time after years of fatty deposits in the vascular system (Arteriosclerosis). After a heart attack the heart muscles are weakened and cannot perform the way they could prior to the attack. Therefore, as the muscles lose their pumping ability the heart cannot work to its full potential causing for the heart to fail. Lastly in cardiomyopathy the heart fails because of other risk factors such as drugs, chemotherapy, and infections. Infections such as pericarditis where the pericardial sac becomes infected causes the heart to not pump effectively which leads to Congestive Heart Failure. The risks factors include hypertension, male gender, diabetes, a diet high in fats and a previous heart attack.…
Cardiac surgeons are people who do treatments and surgeries to treat people with heart and lung disease. They also deal with vessels and organs. There are a lot of different types of operations. There is heart valve repair and replacements, heart defect repair, coronary artery bypass, aneurysm repair, heart transplant, lungs (lung disease). They complete the most surgeries in their field. Grey’s Anatomy influenced me because in that show it’s a bunch of different types of surgeons and I liked cardio the best.…

Muscle contractions tend to be smooth and vary in strengths, depending on the demands placed on them. The variations of strength are called graded muscle responses. There are two ways a muscle contraction can be graded, either by changing the frequency of stimulation or by changing the strength of the stimulation.…
The focus of the investigation explored the fundamental properties of cardiac muscle on a cane toad’s (Bufo marinus) heart and the adaptive ability of the heart to produce a response when subject to different conditions of temperature, stretch on contractile force, substances of acetylcholine, adrenaline and atropine, and increased frequency of stimulus. Regarding Figure 1, the regular heartbeat and contraction force of the toad was identified to demonstrate the difference between atrial contractions and ventricular contractions in a normal environment. In cardiac, skeletal, and some smooth muscle tissue, contraction occurs through a spectacle known as excitation contraction coupling (Freeman et al., 2014). This process converts electrical stimulus from the neurons into a mechanical response, to facilitate muscle movement (McCorry, 2007). The spontaneous, rhythmic generation of action potentials in the intrinsic pacemaker centres of the heart is the basis of the autonomous heartbeat rhythm (Sarnoff et al., 1960).…
“The Tell Tale Heart” by Edgar Allan Poe is a traumatizing story about a person who murdered an innocent old man because he thought that his eye was evil. The story states that the narrator was afraid of the eye and that is why he wanted to rid himself of it. The narrator had many signs of being proven to go to jail or to go to a mental hospital.…
Smooth muscle is located in the walls of the intestines, the stomach and other hollow organs. We are unaware of them because they work automatically. The body uses them for many functions. We are able to push food through our body because of the muscular walls of the intestines contract. We get rid of urine from our body because the muscles in the bladder wall contract. These muscles are very useful. The smooth muscles in a woman's womb or uterus help to push babies out of the body during childbirth. Without these smooth muscles, giving birth would be much harder. We have a smooth muscle in our eye called a pupillary sphincter muscle, which shrinks the size of your…
