  1. CIRCULATORY SYSTEM37-1PG. 942-950 3/21/2011

  2. STANDARD 9A Know how the circulatory/respiratory systems provides cells with O2/nutrients and removes waste such as CO2.

  3. What is the purpose of the circulatory system? Bring O2 in and take CO2 out!

  4. CS Parts: Heart Blood vessels Blood

  5. BLOOD PLASMA 90% WATER PLATELETS WBC RBC HEMOGLOBIN-BINDS O2

  6. BLOOD VESSELS AORTA (HIGHWAY) BRINGS O2 -BLOOD FROM HEART TO BODY ARTERIES (BUSY STREETS) BRINGS O2-BLOOD TO BODY

  7. BLOOD VESSELS CONTD.. • CAPILLARIES ( DRIVEWAYS) • DROPS O2 TO CELLS • PICKS UP CO2 • VEINS (SLOW STREETS) • BRINGS CO2BLOOD TO HEART

  8. DID YOU UNDERSTAND? • WHAT IS THE BIGGEST SUPERHIGHWAY? • AORTA • WHAT ARE THE SMALLEST BLOOD VESSELS? • CAPILLARIES • WHICH VESSELS DROP OXYGEN OFF TO A CELL? • CAPILLARIES • WHAT DO VEINS CARRY? • CARBON DIOXIDE-BLOOD • WHICH VESSEL CARRIES BLOOD FROM HEART TO LUNG? • PULMONARY ARTERY

  9. SVC AORTA PULMONARY ARTERIES RIGHT ATRIUM LEFT ATRIUM PULMONARY VEINS VALVES LEFT VENTRICLE IVC PULMONARY-OF THE LUNG RIGHT VENTRICLE

  10. ATRIA/ATRIUM UPPER CHAMBERS COLLECTS BLOOD VENTRICLES -LOWER CHAMBERS PUMPS BLOOD THICKER MUSCLE

  11. VALVES 1-WAY DOORS KEEPS BLOOD FROM FLOWING BACKWARDS SEPTUM DIVIDES LEFT SIDE FROM RIGHT

  12. GET IT? • THE HEART HAS _______ CHAMBERS. • 4 • ARTERIES TAKE BLOOD WHERE? • AWAY FROM THE HEART • VEINS TAKE BLOOD WHERE? • TO THE HEART • WHAT DOES PULMONARY MEAN? • LUNG

  13. NOW ABOUT THE LUNGS…. CO2 EXCHANGED FOR O2

  14. CLASSWORK/HW • COPY FIGURE 37-3 ON PG. 945 • LABEL! • COLOR RED/BLUE • RED-OXYGEN RICH • BLUE-OXYGEN POOR
