  1. 30.5 Blood 2.1 Atoms, Ions, and Molecules Set up Cornell Notes on pg. 77 • Topic: 30.5 Blood • Essential Question(s): • No EQ   

  2. Crabs have blue blood. Earthworms have green blood. Starfish have yellow blood. Humans have red blood. • Hypothesize what gives blood its color.

  3. Its components (what is inside of it) • In humans hemoglobin, a red pigment that is found in red blood cells, gives human blood its color

  4. KEY CONCEPT Blood is a complex tissue that transports materials.

  5. Director of the American Red Cross • Recruited 100,000 people to donate blood • Developed large scale blood banks during WWII • Resigned from his position when the U.S. military insisted that blood be segregated according to race • He argued that blood has no race.He was correct. Charles Richard Drew (1904-1950)

  6. plasma red blood cells, white blood cells, and platelets Blood is composed mainly of cells, cell fragments, and plasma. • Whole blood is made up of different materials. • plasma • red blood cells • white blood cells • platelets

  7. red blood cell platelet white blood cell • bone marrow manufactures most of the blood components • Red blood cells, white blood cells, and platelets Bone marrow

  8. On the rest of pg. 77, please create a Tree Map of the parts of blood and their functions from the class notes and videos. Blood PlasmaRedWhitePlatelets BloodBlood CellsCells

  9. plasma red blood cells, white blood cells, and platelets • Plasma is a key factor in maintaining homeostasis. • Liquid component of blood • mostly water (93% by volume) • contains dissolved proteins, glucose, mineral ions, hormones and carbon dioxide

  10. Predict what you think might happen to your blood if you become dehydrated. Because the blood contains so much water, being dehydrated would make the blood thicker, affecting blood flow, and homeostasis.

  11. transport oxygen to cells and carry away carbon dioxide • have no nuclei and contain hemoglobin • life span (120 days) • Determine blood type • Red blood cells make up 40-45 % of all blood cells.

  12. RBCs have surface protein markers that define your blood type • If you receive blood with a protein marker different from your own: • immune system will attack the foreign blood cells, causing them to clump- can result in death

  13. ABO blood group: A, B, AB, and O • O has no marker and can be donated to anyone • AB can accept any blood type • Rh factor: Rh+ or Rh- • Anyone can receive Rh- • Rh- cannot receive Rh+ • immune system will make Rh+ cells burst **Blood must be checked for both ABO and Rh factor • blood types must be compatible for transfusions

  14. Please copy down blood type table on pg. 76 For example I am A positive (A+)

  15. red blood cell platelet white blood cell • White blood cells fight pathogens and destroy foreign matter. • Contain no hemoglobin • Also part of the immune system

  16. platelets fibrin white blood cell red blood cell • Platelets help form clots that control bleeding. • Cluster around a wound • Blood above dries out to form a scab • Blood clots that form in blood vessels present serious risk to health- can cause stroke or heart attack • Inability to form clots is equally serious- Hemophilia

  17. Please add to your tree map with notes from the videos
