  1. The Circulatory System!!!!!

  2. http://kidshealth.org/kid/htbw/CSmovie.html?tracking=81347_A

  3. What is it? The organ system the circulates blood throughout the body What does circulate mean? To move or flow in a circle

  4. Functions of The Circulatory System Blood Cells carry energy/glucose (from food person eats) and Oxygen (that person breathes in) to cells all over the body 2. Blood takes Carbon Dioxide and other waste out of cells

  5. We all know that oxygen is the key to living. It's in the air you breathe, in your lungs and in your blood. What you might not know is how oxygen gets into your blood and how the blood carries oxygen through your body.

  6. How does the oxygen get in the blood? You breathe air in through your nose and mouth. It then makes its way intoyour lungs . Oxygen then sticks to red blood cells as they pass through the lungs on their path throughout the body - now the oxygen is in the blood.

  7. How does energy/glucose from food get into you blood? Glucose: is the main sugar found in blood, taken from the food we eat. Once almost fully digested, food moves through the intestines, the nutrients are absorbed through the walls of the intestines and put into the blood.

  8. 3 Parts of Circulatory System • Heart • Blood vessels • Blood

  9. 3 Parts of Circulatory System • Theheartpumps the blood. • The blood vesselsare tubes that carry blood. • Thebloodcarries oxygen & nutrients to body cells.

  10. Parts of the Circulatory System HEART: Muscular organ that pumps blood all around the body. http://www.bostonscientific.com/templatedata/imports/HTML/CRM/heart/interact_6.html

  11. The Heart The heart has 4 chambers (sections)

  12. Remember Functions of Circulatory System? • Blood carries Oxygen to parts of the body • The lungs work with the heart to do this

  13. Blood with oxygen in it is shown as red Blood without oxygen is shown as blue Red = blood has oxygen in it Blue= blood without oxygen

  14. Blood Flow Visual • http://www.bostonscientific.com/templatedata/imports/HTML/CRM/heart/interact_5.html

  15. Step 1. Blood returns to your heart from your body and lungs Oxygen-poor blood from your body flows into your right atrium. At the same time, oxygen-rich blood from your lungs flows into your left atrium. Blood Flow Steps

  16. Step 2. Blood flows from the upper to the lower chambers. Blood flows from your right atrium into your right ventricle. At the same time, blood flows from your left atrium into your left ventricle.

  17. Step 3. Blood is pumped back out to your lungs and body. Your right ventricle pumps blood out of your heart to your lungs, where the blood's oxygen supply is replenished. At the same time, your left ventricle pumps blood — once again full of oxygen — out of your heart to your body. To body To lungs For oxygen

  18. Blood Flow Poster Task: create a poster on 8x11 paper explaining how blood flows between the heart, lungs and body

  19. Exit • Which of the following is not a function of the circulatory system? • Take oxygen to cells • Remove carbon dioxide from cells • Take energy to cells • Rake water to cells 2. Name the 1 of the 3 parts of the circulatory system

  20. Thursday Warm Up 1.

  21. Thursday

  22. Textbook 66B for Heart Foldable • Label each chamber on the outside

  23. Parts of the Circulatory System BLOOD VESSELS: Blood travels through your body in hollow tubes called blood vessels. • There are 3 types of blood vessels: arteries, veins, capillaries

  24. Arteries • A artery is a blood vessel that carries oxygenated blood away from the heart. • Biggest type of blood vessel

  25. Veins • A blood vessel that carries blood back to the heart.

  26. Capillaries • A narrow blood vessel that connects arteries with veins.

  27. Parts of the Circulatory System BLOOD: Special tissue that carries important gases and nutrients to and from all parts of your body. • Made up of 3 different types of cells that sit in a liquid called plasma

  28. Plasma • The liquid that makes up blood. Carries minerals and waste. • About 60% of blood is plasma.

  29. Red Blood Cells • Blood cells that pick up oxygen and transport oxygen throughout the body. • Hemoglobin is the compound that makes these cells red.

  30. White Blood Cells • Blood cells that help your body fight infections

  31. Platelets • Cell fragments that help to form clots when a blood vessel is damaged.
