Presentation Transcript


  1. Blood & Blood & circulation circulation

  2. Circulation Your body resembles a large roadmap, There are routes or arteries that take you downtown to the heart of the city.

  3. 3 Major Parts of the Circulatory system Blood Vessels - routes blood travels Heart pumps or pushes blood through body Blood carries important *stuff through body * Stuff includes oxygen, food, & waste

  4. # 1 Blood Vessels : One Way Streets Blood Vessels resemble very long and skinny tunnels that are all through your body.

  5. 3 Types of Blood Vessels Arteries Arteries Capillaries Capillaries Veins Veins * Click on each blood vessel to explore its function in circulation

  6. #2 The Heart 4 chambers ( or compartments ) 2 upper chambers : Left Atrium Right Atrium 2 lower chambers : Left Ventricle Right Ventricle

  7. Lub Dub If you listen to your heartbeat, it makes a lub dub sound. The lub is when blood is pushed out of the heart into the body and the dub is the reloading of the heart with more blood ready to push it out to the body

  8. Blood Flow through the Human Body Blood with little oxygen is pumped from the Right Atrium through a valve to the Right Ventricle and through another valve into the Pulmonary Vein. The Pulmonary Vein sends it to the Lungs to pick up Oxygen. It s sent from the Lungs through Pulmonary Arteries to the Left Atrium through a valve to the Left Ventricle. The Left Ventricle sends it through a valve to the Aorta. The Aorta is a series of branches that sends oxygenated blood throughout the body.

  9. Heart Rate can be determined using a Stethoscope Average Heart Rate of some Mammals 376 Heartbeats per 400 300 minute 200 200 70 50 40 100 28 30 9 0 camel human lion mouse cow cat elephant grey whale Mammals

  10. Heart Facts Hold out your hand and make a fist. If you're a kid, your heart is about the same size as your fist, and if you're an adult, it's about the same size as two fists. Your heart beats about 100,000 times in one day and about 35 million times in a year. During an average lifetime, the human heart will beat more than 2.5 billion times. Give a tennis ball a good, hard squeeze. You're using about the same amount of force your heart uses to pump blood out to the body. Even at rest, the muscles of the heart work hard--twice as hard as the leg muscles of a person sprinting.

  11. Your Blood is made of Plasma Liquid part of blood Red Blood Cells They carry oxygen to all parts of the body

  12. White Blood Cells Fight and kill germs that may enter your bloodstream

  13. Platelets Form scabs when you cut yourself Helps stop the bleeding

  14. Blood Types There are 4 main Blood Types: Type A, Type B, Type AB, and Type O Dr. Charles Drew* click on link for history of the Blood Bank
