  1. Cardiovascular System Essentials Created by S. Falwell Permission granted for teachers to use with link to http://comelearnmore.com/

  2. Get in the groove to move(your Blood That is) http://www.youtube.com/watch?v=LqhvmUEdOYY

  3. The heart has 4 chambers Atrium (top) Atrium (top) Ventricle (bottom) Ventricle (bottom)

  4. Remember: images show what the doctor sees when looking at the patient (so the patient’s right side is on your left) Left Atrium Right Atrium Left Ventricle Right Ventricle

  5. Divided by the septum, valves Septum

  6. Path of Blood Flow 1. Blood flows from body through Veins 6. Back to Heart through Pulmonary Vein 2. Into Right Atrium 7. Into Left Atrium 3. Into Right Ventricle 8. Into Left Ventricle 4. Through Pulmonary Artery 9. Out to body through Artery 5. To Lungs 10. Gas exchange (O2 and CO2) at capillaries

  7. 3 kinds of blood vessels Memory Tricks Arteries = flow A-Away from the heart Veins = think of the V like an arrow shape pointing to the heart Capillaries = gets a couple other blood vessels to join together (biggest word but smallest blood vessel)

  8. How do the nutrients and gases get into the blood? Osmosis is diffusion through a membrane Diffusion is the movement of molecules from an area of high concentration to an area of low concentration

  9. Blood Carrying Facts • Hemoglobin (iron-containing protein in red blood cells) carries oxygen • Sickle Cell Anemia (recessive genetic disease) results in cresent-shaped red blood cells that do not carry oxygen as well

  10. What’s in Blood? Red Blood Cells Platelets White Blood Cells Plasma

  11. Blood TypesA,B, AB,O+ or – RH factor
