Heartclass

  1. 1. The Human Heart
  2. 2. Parts of the Internal Heart 6 1 7 2 8 9 3 4 10 5 11
  3. 3. Superior vena cava Receives oxygen poor blood from upper body. Pacemaker. Sends electrical signals to cause heart muscles to contract. Right atrium. Receives oxygen poor blood from the superior vena caba and i.vc.
  4. 4. Triscupid Valve Control blood flows into right ventricle. Right ventricle. Channels oxygen poor blood into the pulmonary arteries. Pulmonary arteries. Transport oxygen rich blood to the lungs.
  5. 5. Pulmonary Veins. Transport oxygen rich blood from lungs into the atrium. Left atrium. Receives oxygen rich blood from the pulmonary veins
  6. 6. Bicuspid valve Control blood flow into left ventricle. Left ventricle. Pumps oxygen rich blood into aorta.
  7. 7. Aortic Valve Prevents blood from going back into the left ventricle
  8. 8. Tricuspid Valve Prevents backflow of blood to the right atrium 3 cusps
  9. 9. Aorta Blood flows from the aorta throughout the entire body Largest vessel in the body
  10. 10. Descending aorta. Transport oxygen rich blood to lower body. Facts. Your heart pumps to 35L of blood each minute. When you are active. It can continues to beat during transplant surgery, after all nerves have been cut.
  11. 11. Right Atrium Collecting chamber Blood is forced to the right ventricle
  12. 12. Veins and arteries Jugular veins Subclavian artery and vein. Hepatic artery and veins Inferior vena cava. Tibial artery and vein. Caratoid artery. Descending aorta
  13. 13.  Renal artery and veins. Femoral artery and vein.
  14. 14. Path of Blood FlowPlace the following items in the correct sequence: body tissue, aorta, bicuspidvalve, left atrium, lungs, pulmonary trunk, pulmonary arteries, left ventricle,pulmonary veins, right atrium, right ventricle, tricuspid valve, aortic valve,pulmonary valve. Oxygen poor blood is collected from the inferior and __________________ ________. It is released into the _________ _______where it moves through the _________ valve into the __________________. When the right ventricle contracts, blood is forcedthrough the _________ valve into the ____________ _______ whichsplits into the left & right pulmonary __________. Blood is taken viathe arteries to the _____ where oxygen & carbon dioxide diffusethrough the simple squamous tissue. Oxygen-rich blood then returnsto the heart via the ___________ ________ which empty into the_________ ________. Once the atrium contracts, the blood passesthrough the __________ ________ into the _________ _________.Once the ventricle contracts blood is forced through the _________valve and out of the _________ to travel to the _______ ________ .
  15. 15. Right Ventricle Receives blood from the superior and inferior vena cava
  16. 16. Path of Blood Flow: Answer Sheet 1. Superior Vena Cava 2. Right Atrium 3. Tricuspid Valve 4. Right Ventricle 5. Pulmonary Valve 6. Pulmonary Trunk 7. Pulmonary Arteries 8. Lungs 9. Pulmonary Veins 10. Left Atrium 11. Bicuspid Valve/Mitral valve 12. Left Ventricle 13. Aortic Valve 14. Aorta 15. Body Tissue
