Human Heart

Transcript: The Heart: More than 64 million Americans have heart problems. They don't always start at birth. When there are problems at birth its called Congenita. When they happen after birth it’s called Acquired. About eight out of every 1,000 newborns have heart defect(s.) Where does the blood go? There are 4 chambers in the heart: the biggest one is the right atrium, that has very thin walls. The left atrium that has thicker walls but is smaller than the right atrium. The left and right ventricles. The heart pumps about five liters per ventricle. The ventricles are hollow. Two ventricles pump blood out of the heart.Humans have two different circulatory systems. One is the Pulmonary circulation,that is short loop from the heart to the lungs and back. The other one is systemic circulation. That goes from the heart to everywhere else in the body and back. Thank You! Human Heart By:Karlie Koehler A little more about the heart: When at rest the heart only pumps a little bit because not much oxygen is needed. When exercising you need much more oxygen so the heart pumps much faster. It beats about 72 times a minute (10 liters), 100,000 times a day (120 liters), 30 million times a year (1440 liters), and 2.5 billion times in a 70 year life-time (100,800 liters). Each pump takes about eight tenths of a minutes. Veins: Heart Problems: Arteries: When blood is in the arteries it goes to smaller arterioles then to capillaries. When its in the capillaries blood stream it delivers oxygen and nutrients and picks up waste material. Then it goes back through capillaries then into venules. After that, it goes into larger veins until it reaches the vena cava. Blood from the arms and head go to the heart and then through the superior vena cava. The blood in the lower body goes through the inferior vena cava. Arteries carry blood away from the heart. The walls of the artery have three layers. The endothelium is on the inside and is smooth for the blood to travel through. The media is the middle and that is made of elastic tissue and muscle. Then, the adventitia is very thick so it that it can protect the artery. Veins carry blood back to the heart. They are not as muscular as arteries. Veins have the same three layers but are not are flexible and are thinner. Also, they have valves to make sure that the blood does not travel backwards. the two biggest veins are the superior and inferior. They are located above and below the heart.

Transcript: The Heart Arrhythimia This is an abnormal rhythm of the heart. There are various types of arrhythmias stenosis- when valves dont open properly regurgitation- when valves dont close mitral valve prolapse Treatments- Medications — clotbusters Coronary Angioplasty Coronary Artery Bypass Graft Surgery Heart Failure The Anatomy of the Heart The Human Heart by Ciara Bailey Heart Attack This doesn't mean that the heart stops beating. Heart failure, sometimes called congestive heart failure, means the heart isn't pumping blood as well as it should. treatments- Medications or Heart Valve surgery Tachycardia is when the heart rate is more than 100 beats per minute. Heart Valve Problems when the blood flow to a part of the heart is blocked by a blood clot. If this clot cuts off the blood flow completely, the part of the heart muscle supplied by that artery begins to die. Most people survive their first heart attack Treatments- Medications, Pacemaker, or Cardiac Defibrillation A kitchen faucet would need to be turned on all the way for at least 45 years to equal the amount of blood pumped by the heart in an average lifetime the average heart beats about 72 times a minute, 100,000 times a day, 3,600,000 times a year and 2.5 billion times in a lifetime Though weighing only 11 ounces on average, a healthy heart pumps 2,000 gallons of blood through 60,000 miles of blood vessels each day Interesting Facts The fetal heart rate is approximately twice as fast as an adult’s, at about 150 beats per minute. By the time a fetus is 12 weeks old, its heart pumps an amazing 60 pints of blood a day Diseases & Defects Bradycardia is when the heart rate is less than 60 beats per minute The heart is the organ that helps supply blood and oxygen to all parts of the body

Description Description Human resources specialists are responsible for recruiting, screening, interviewing and placing workers. They may also handle employee relations, payroll, benefits, and training. Human resources managers plan, direct and coordinate the administrative functions of an organization. Duties Duties Subtopic 1 you need good communication skills PICTURES The human resources department handles a range of different functions within an organization. The department is responsible for hiring and firing employees, training workers, maintaining interoffice relationships and interpreting employment laws. function Function TIMELINE 2018 MAP Location 2 Location 3 Location 1 Definitely collaborative and good relations should exist between HR and other Departments. HR, as you say, is responsible for a number of areas, but decisions are usually in conjunction with other functions. HR may have established policies and programs, but generally there would have been discussion and executive approval and areas like recruitment and compensation would have a great deal of functional management input whether in final selection of a candidate or job evaluation and performance management which usually impact on compensation.

Transcript: When you go for a checkup, your doctor uses a stethoscope to listen carefully to your heart. A healthy heart makes a lub-dub sound with each beat. This sound comes from the valves shutting on the blood inside the heart. Thank You! Keep Your Heart Happy How does the heart beat? Before each beat, your heart fills with blood. Then its muscle contracts to squirt the blood along. When the heart contracts, it squeezes — try squeezing your hand into a fist. That's sort of like what your heart does so it can squirt out the blood. Your heart does this all day and all night, all the time. The heart is one hard worker! Your heart is really a muscle. It's located a little to the left of the middle of your chest, and it's about the size of your fist. There are lots of muscles all over your body — in your arms, in your legs, in your back, even in your behind. We Got the Beat Working That Muscle It's Great to Circulate The heart is made up of four different blood-filled areas, and each of these areas is called a chamber. There are two chambers on each side of the heart. One chamber is on the top and one chamber is on the bottom. Pretty Cool — It's My Pulse! Human Heart Heart Parts Why do we have a heart? Listen to the Lub-Dub Most kids are born with a healthy heart and it's important to keep yours in good shape. Here are some things that you can do to help keep your heart happy You probably guessed that the blood just doesn't slosh around your body once it leaves the heart. It moves through many tubes called arteries and veins, which together are called blood vessels. These blood vessels are attached to the heart. The blood vessels that carry blood away from the heart are called arteries. The ones that carry blood back to the heart are called veins. Even though your heart is inside you, there is a cool way to know it's working from the outside. It's your pulse. You can find your pulse by lightly pressing on the skin anywhere there's a large artery running just beneath your skin. Two good places to find it are on the side of your neck and the inside of your wrist, just below the thumb. We have a heart because without it we would not be alive. Sure. But still, isn't it intriging that if you are shot in the heart and therefore the heart function immediately stops, that your brain and other vital organs still continue to function, to live, for a few more seconds? This would indicate that the heart is not the sole engine of our lives. There is something else that engages the heart and all other cells and organs and empowers them with life. This "something else" refers to the Life-force, the energy that is life itself and that mobilises our poor lifeless bodies into functioning. And the heart plays a vital role in that. 62 ECG bpm
