  3. 3. What is the heart ? The heart is a vital organ, that is responsible for for pumping oxygen rich blood, and the blood gives oxygen to the body and the body cells take the oxygen from the blood.
  4. 4. Blood Circulation Part 1 ★ The blood starts at the heart in the right atrium ★ then the blood pushes the tricuspid valve open ★ the blood goes to the right ventricle to get pumped to the lungs
  5. 5. Blood circulation part 2 ★ The oxygen rich blood goes through the left atrium ★ the blood then goes to the left mitral valve and into The left ventricle. ★ The blood gets pumped to the body ★ The body cells take the oxygen from the blood ★ Then when the blood is out of oxygen it starts this cycle all over again. this is called the circulation of blood.
  6. 6. The Layers of the Heart -The heart has three layers. The outer fluid filled sac layer is called the pericardium {It is Double layered membrane that cushions the heart helps the heart prevent friction} -The middle layer is the muscle -The inner layer is called the endocardium. {the inner tissue of the heart.}
  7. 7. Left valves The left side of the heart receives the blood with lots of oxygen. the blood fills up the atrium and builds pressure to open the mitral valve The mitral valve is there to keep blood going one direction Then the blood goes to the aortic valve. The aortic valve does the same thing as the mitral valve. Right Valves After the blood goes in the right atrium there is there is the tricuspid valve. How that Works. First the depleted blood goes into the Right atrium. When it is filled, the tricuspid valve opens up and lets the blood through to the right ventricle.Then the blood goes up the pulmonary valve. The valves open and close so the blood goes 1 direction.
  8. 8. The Four Valves
  9. 9. Heart disease ❖ The most common heart disease is called coronary artery disease. (When your coronary artery. gets narrowed by plaque. [plaque is waxy stuff.) So the heart can’t get enough blood. It causes: ❏ chest pains ❏ And most commonly HEART ATTACKS!!! ❖ cardiovascular disease is like coronary artery It causes: ❏ plaque ❏ It can cause blood clots (blood clots can cause heart attacks or stroke)
  10. 10. How heart attacks happen The most common way of heart attacks is coronary artery disease.heart does not pump In a heart attack the heart doesn’t pump for more than 20 minutes If it’s not treated the muscle stops pumping and dies Indications: ● ● ● ● ● Upper body pains Cold Sweat Nausea Puking Trouble Breathing
  11. 11. How to prevent a heart attack 1.Aerobatic Exercising is a great way to prevent a heart attack from happening{normal exercising is also fine} 2.Don’t smoke 3.Have a healthy the blood pressure 4.Have a healthy diet
  12. 12. Heart Diagrams
  13. 13. Fun Facts ★ Your heart is about the size of your fist. ★ Your heart is slightly to the left of the middle of your 2 lungs. ★ The ventricles are the main pump of the heart. ★ The septum is a layer that separates the 2 ventricles and atriums. ★ Your heart is a vital organ
  14. 14. How it connects to our unit The central idea: Systems have structures and processes which interact to sustain life. Our project connects the unit because the heart has an important system and structures that help the system and processes which we need to sustain life.By: ● pumping blood to the rest of our body ● and pumps oxygen and nutrients ● The blood that the heart pumps is full of oxygen which the body needs
