  10. Check for Understanding Using your iPads, go to www.awwapp.com to get to the online whiteboard Write in the answer to question 1 and hold your iPads so I can see them. • What are the three main parts of the circulatory system? Now tap the menu button and tap clear to clear your whiteboard and answer question 2. Hold up your iPads when you are finished so I can see them. 2. What are the three types of blood vessels in the human circulatory system?

  11. Blood Vessels • ______________ • carry oxygen-rich blood away from the heart and to the body • have thicker walls to withstand higher blood pressure • ______________ • carry oxygen-poor blood to the heart • have valves to prevent blood from flowing back in the wrong direction • ______________ • are the smallest blood vessels • so narrow that blood cells pass through in a single file • deliver oxygen and nutrients to all cells of the body

  12. Blood Vessels • arteries • carry oxygen-rich blood away from the heart and to the body • have thicker walls to withstand higher blood pressure • ______________ • carry oxygen-poor blood to the heart • have valves to prevent blood from flowing back in the wrong direction • ______________ • are the smallest blood vessels • so narrow that blood cells pass through in a single file • deliver oxygen and nutrients to all cells of the body

  13. Blood Vessels • arteries • carry oxygen-rich blood away from the heart and to the body • have thicker walls to withstand higher blood pressure • veins • carry oxygen-poor blood to the heart • have valves to prevent blood from flowing back in the wrong direction • ______________ • are the smallest blood vessels • so narrow that blood cells pass through in a single file • deliver oxygen and nutrients to all cells of the body

  14. Blood Vessels • arteries • carry oxygen-rich blood away from the heart and to the body • have thicker walls to withstand higher blood pressure • veins • carry oxygen-poor blood to the heart • have valves to prevent blood from flowing back in the wrong direction • capillaries • are the smallest blood vessels • so narrow that blood cells pass through in a single file • deliver oxygen and nutrients to all cells of the body

  15. Check for Understanding Using awwapp again, answer these questions one at a time. • Why do arteries need to be thicker than veins? • Why do veins need to have valves? • Which blood vessels carry blood to the heart? • Which blood vessels carry blood away from the heart?

  16. Blood Blood is made of: • A liquid called ____________ • Red blood cells, also called ____________ • White blood cells, also called ____________ • ____________, also called thrombocytes

  17. Blood Blood is made of: • A liquid called plasma • Red blood cells, also called ____________ • White blood cells, also called ____________ • ____________, also called thrombocytes

  18. Blood Blood is made of: • A liquid called plasma • Red blood cells, also called erythrocytes • White blood cells, also called ____________ • ____________, also called thrombocytes

  19. Blood Blood is made of: • A liquid called plasma • Red blood cells, also called erythrocytes • White blood cells, also called leukocytes • ___________, also called thrombocytes

  20. Blood Blood is made of: • A liquid called plasma • Red blood cells, also called erythrocytes • White blood cells, also called leukocytes • Platelets, also called thrombocytes

  21. Blood Cells • Red blood cells have no __________.

There are many different types of white blood cells • Platelets are cell __________ that help with blood _______

  22. Blood Cells • Red blood cells have no nucleus. They contain a protein called ____________ that carries ____ to cells and ____ away from cells. • White blood cells help the body fight off ___________. There are many different types of white blood cells • Platelets are cell __________ that help with blood _______

  23. Blood Cells • Red blood cells have no nucleus.

  33. Blood Circulation Through the Body • The right side of the heart pumps blood from the heart to the lungs. This is called ________________ circulation. • In the lungs, CO2 in the blood is _______________ for O2 • Oxygen-rich blood flows from the lungs, into the left side of the heart, and to the rest of the body. This is called _______________ circulation.

  34. Blood Circulation Through the Body • The right side of the heart pumps blood from the heart to the lungs. This is called pulmonary circulation. • In the lungs, CO2 in the blood is _______________ for O2 • Oxygen-rich blood flows from the lungs, into the left side of the heart, and to the rest of the body. This is called _______________ circulation.

  35. Blood Circulation Through the Body • The right side of the heart pumps blood from the heart to the lungs. This is called pulmonary circulation. • In the lungs, CO2 in the blood is exchanged for O2 • Oxygen-rich blood flows from the lungs, into the left side of the heart, and to the rest of the body. This is called _______________ circulation.

  36. Blood Circulation Through the Body • The right side of the heart pumps blood from the heart to the lungs. This is called pulmonary circulation. • In the lungs, CO2 in the blood is exchanged for O2 • Oxygen-rich blood flows from the lungs, into the left side of the heart, and to the rest of the body. This is called systemic circulation.

  37. Check for Understanding Using awwapp, answer these questions one at a time • Which system carries oxygen rich blood – systemic or pulmonary? • Which system carries oxygen poor blood back to the heart?
