  3. Index CARDIOVASCULAR SYSTEM Cardiovascular system means the system of heart and blood vessels of human body. So the name itself indicates that

  4. Index COMPONENTS OF CARDIOVASCULAR SYSTEM Heart BloodVessels Blood

  5. Index THE HEART HAVE: • 2 atriums • 2 ventricles HAVE 4 valves: • Aorticvalve • Pulmonaryvalve • Mitral valve • Tricuspidvalve It`slocated in themiddle of thechest , calledthemediastinum

  6. Index PARTS OF THE HEART

  7. Index LOCALITATION OF THE HEART

  8. Index VALVES OF THE HEART

  9. Index Index THE HEART IT´S A muscular organ and its size is like a closed hand itsfunction is Bloodpumpingtoallparts of thebody. AND • Heart have three layers: • Pericardium • Myocardium • Endocardium.

  10. Index LAYERS OF THE HEART Endocardium Myocardium Pericardium

  11. Index THE ENDOCARDIUM • The endocardium is the innermost layer of tissue that lines the chambers of the heart.

  12. Index THE MYOCARDIUM • It`s the middle layer of the hearth , made of cardiac muscle, contracts to push out blood.

  13. Index THE PERICARDIUM • It`s a double walled sac that contains the heart and the roots of the great vessels.

  14. Index PHYSIOLOGY OF THE CARDIOVASCULAR SYSTEM HEART CONDUCTION SYSTEM CARDIAC CYCLE HEART SOUNDS

  16. Index CARDIAC CYCLE

  17. Index THE CARDIAC CYCLE Isdivided in to MinorCirculation MajorCirculation

  18. Index MinorCirculation • Therightventriclesendbloodtothepulmonaryartery. • Thepulmonaryarterysendthebloodtothelungswherebloodisoxygenated. • Thepulmonaryveinssendtheoxygenatedbloodtotheleftatrium.

  19. Index MajorCirculation • Theleftventriclecontracts and sendoxygenatedbloodtotheaorta. • The aorta passthebloodoxygenatedtothearterioles and thecapillaries. • The superior and inferior cava veinsreturnsthebloodtotherightatrium.

  20. Index CARDIAC SOUNDS THE HEART HAVE TWO SOUNDS SYSTOLE DIASTOLE It`sthesecoundsoundwhentheoutflow of thebloodtoeveryparts of thebody. It`sthefirstsoundbecauseindicatetheentry of blood in theventricles.

  21. Index THEY ARE THE ROUTES OF THE BLOOD CONDUCTION CALLED Capillaries Arteries Veins

  22. Index ARTERIES The principal functionistransporttheoxigenatedbloodtoallthebody Anarteryis a elasticbloodvesselsthattransportbloodaways of theheart.

  23. Index PRINCIPAL ARTERIES • AorticArch • Ascending Aorta

  24. DESCENDANT AORTA • thoracic aorta Index • Abdominal aorta

  25. Index CAPILLARIES Microscopicbloodvesselswhereexchange of nutrientswithtissues.

  26. Index VEINS • A veinis a vesselthatcarriesbloodlow in oxigencontentfromthebody back totheheart

  27. Index PRINCIPAL VEINS SUPERIOR CAVA VEIN INFERIOR CAVA VEIN

  28. Index It`s a specialized tissue of body that exists in fluid form. • Platelets

  29. Index RED BLOOD CELLS(RBCs) They are the mostcommontype of bloodcell • Theytransporttheoxygen and thenutrientstoallthetissues of thebody

  30. White Blood Cells (WBCs) They are cells of theimmunesysteminvolved in defendinthebodyagainstbothinfectiousdisease and foreignmaterials.

  31. Index White Blood Cells (WBCs) Isdivided in THE GRANULOCYTES THE AGRANULOCYTES Neutrophil Lymphocyte Eosinophil Monocyte Basophil

  32. Index Platelets, or thrombocyte are small irregular fragments of cell . THE PLATELETS They are important to the coagulation of the blood

  33. Index CHARACTERISTICS OF BLOOD PLASMA

  34. Index IMPORTANCE OF THE CARDIOVASCULAR SYSTEM • Transporting blood, nutrients and oxygen (O2) to all parts of the body. • Collect the waste products and carbon dioxide (CO2).
