Heart Disease Prezi
Transcript of Heart Disease Prezi
Elijah Fenelon & Cyrus Contreras What is the heart and how does it work? As you should already know, your heart is one of your most important organ in your body. Its what helps keep you alive! Your heart is basically a living pump, and its the size of your fist. The heart pumps microscopic cells called blood cells around your body . Red blood cells carry oxygen and nutrients to the whole body. By doing this your heart keeps you alive and gives energy to your body to allow you to perform simple tasks like lifting a book, walking, and a lot of other things. The heart is like a battery, that recharges when you sleep. Prevention: The Basics: Commercial: Animation: Symptoms: In this presentation, we will teach you about the heart. You will also see the types of heart diseases and how it affects it. You guys will also learn a bit on how it can be prevented. Enjoy! The heart is like a pump in many ways, it pushes material in specific directions, and like all living things and objects, they can all break down. What diseases could you get
for your heart? How will it affect me? Now the heart can break down and one way
that happens is from heart disease. What is heart disease? Heart disease is the name given to all the different heart diseases. There are different diseases that can be found in the heart that may affect the whole thing, or just a few parts of it. All heart diseases belong to the category of cardiovascular diseases, because heart means 'cardio'. What is Heart Disease? There are two types of blood cells: red blood cells and white blood cells. for example the heart has several parts For example, the heart is made up of different parts. The heart is made of many tubes called veins and arteries. It has 4 main chambers, right atrium, right ventricle, left atrium, and left ventricle. The heart also has 3 layers. The smooth inside lining of the heart is called the endocardium. The middle layer of heart muscle is called the myocardium. It is surrounded by a fluid filled sac call the pericardium. Types of Heart Diseases and Causes -Coronary Artery Disease -Enlarged Heart (Cardiomegaly)
-Heart Attacks -Irregular Heart Rhythm
-Heart Valve Disease -Sudden Cardiac Death
-Marfan Syndrome -Heart Muscle Disease (Cardiomyopathy) There are five strategies of medications that help prevent heart disease. 1st: Do not smoke or use tobacco 2nd: Exercise for 30 minutes on most days of the week 3rd: Eat a heart-healthy diet 4th: Maintain a healthy weight 5th: Get regular health screenings Bibliography http://angioplasyexperts.com/types-of-heart-diseases.htm

Rate of age that might have heart disease:
8% of children between the ages of 2 and 15
30% of children between the ages of 16 and 20
50% of people between the ages of 21 and 25
69% of people between the ages of 26 and 39 Did You Know? Coronary heart disease is caused when the coronary arteries clog up. Your body is not use to having material blocking your arteries. When they become partly clogged there is an insufficient supply of oxygen and nutrients to the body, making it harder to perform physical tasks. When a person with this disease tries to perform energy consuming tasks they get chest pains. that person will experience this condition is called angina. Facts about the heart and heart disease. Did You Also Know?
The average weight of a healthy female human heart is 9oz (255g).
A man's heart is usually slightly bigger at around 10.5oz (300g). Did You (Also) Know? Tomatoes can prevent heart disease. Did You Also (Also) Know? Your heart beats 101,000 times a day. During your lifetime it will beat about 3 billion times and pump about 800 million pints (378 million litres) of blood. A normal heart beats 70 to 80 times a minute. Over 70 to 80 years, it gives a few billion beats. An enlarged heart (cardiomegaly) can have various causes. But it's usually caused by high blood pressure (hypertension) or coronary artery disease. An enlarged heart may not pump blood effectively, resulting in congestive heart failure. Cardiomegaly may improve over time. But most people with an enlarged heart need lifelong treatment with medications. The heart muscle requires a constant supply of oxygen-rich blood to nourish it. The coronary arteries provide the heart with this critical blood supply. If you have coronary artery disease, those arteries become narrow and blood cannot flow as well as they should. Fatty matter, calcium, proteins, and inflammatory cells build up within the arteries to form plaques of different sizes. The plaque deposits are hard on the outside and soft and mushy on the inside.
When the plaque is hard, the outer shell cracks (plaque rupture), platelets (disc-shaped particles in the blood that aid clotting) come to the area, and blood clots form around the plaque. If a blood clot totally blocks the artery, the heart muscle becomes "starved" for oxygen. Within a short time, death of heart muscle cells occurs, causing permanent damage. This is a heart attack. Arrhythmias may be caused by many different factors, including:
-Coronary artery disease.
-Electrolyte imbalances in your blood (such as sodium or potassium).
-Changes in your heart muscle.
-Injury from a heart attack.
-Healing process after heart surgery.
-Irregular heart rhythms can also occur in otherwise normal, healthy hearts. According to the American Heart Association, about 5 million Americans are diagnosed with heart valve disease each year. When the ventricles are full, the tricuspid and mitral valves shut. This prevents blood from flowing backward into the atria while the ventricles contract. As the ventricles begin to contract, the pulmonic and aortic valves are forced open and blood is pumped out of the ventricles. Blood from the right ventricle passes through the open pulmonic valve into the pulmonary artery, and blood from the left ventricle passes through the open aortic valve into the aorta and the rest of the body. When the ventricles finish contracting and begin to relax, the aortic and pulmonic valves shut. These valves prevent blood from flowing back into the ventricles. This pattern is repeated over and over with each heartbeat, causing blood to flow continuously to the heart, lungs, and body. Sudden cardiac death (SCD) is a sudden, unexpected death caused by loss of heart function (sudden cardiac arrest). It is the largest cause of natural death in the U.S., causing about 325,000 adult deaths in the U.S. each year. SCD is responsible for half of all heart disease deaths. Marfan syndrome is an inherited disease that affects the body's connective tissue, which provides the strength, support and elasticity to tendons, cartilage, heart valves, blood vessels, and other vital parts of the body. For people with Marfan syndrome, the connective tissue lacks strength due to its abnormal chemical makeup. The syndrome affects the bones, eyes, skin, lungs, and nervous system, along with the heart and blood vessels. The condition is fairly common, affecting 1 in 5,000 Americans. It is found in people of all races and ethnic backgrounds. Cardiomyopathy, or heart muscle disease, is a type of progressive heart disease in which the heart is abnormally enlarged, thickened, and/or rigid. As a result, the heart muscle's ability to pump blood is weakened, often causing heart failure and the backup of blood into the lungs or rest of the body. The disease can also cause abnormal heart rhythms. Usually, cardiomyopathy begins in the heart's lower chambers (the ventricles), but in severe cases can affect the upper chambers, or atria. Now how you can prevent it from happening We hope that this lesson has your hearts all
'fired up'! We also hope that you kids know
how important the heart is and we your
hearts are full of 'heat' and kindness, instead of cold and rudeness. Thanks for watching
