1 what are the main functions of blood
1. What are the main functions of blood?

A. Transports O2, CO2, nutrients, wastes, & hormones

B. Regulates body temperature and pH

C. Protectionby: 1. stopping fluid loss by clotting

2. protects against disease

2 what is blood made of
2.What is blood made of?
  • Plasma
  • water
  • Plasma proteins
  • 1% carbs, lipids, vitamins, hormones, & electrolytes
  • Cells
3 name the 3 types of blood cells their function
3. Name the 3 types of blood cells & their function.

1. Red Blood Cells

  • transport gases

2. White Blood Cells

  • protect against disease

3. Platelets

  • clot blood
4 where are rbcs made what is their structure
4. Where are RBCs made? What is their structure?
  • Made in Red Bone Marrow by stem cells
  • No nucleus or organelles
    • bi-concave shape
    • so they are lighter & travel faster
    • also allows them to hold more O2
5 how do rbcs carry oxygen
5. How do RBCs carry oxygen?
  • RBCs contain hemoglobin - an oxygen carrying protein
    • Hemoglobin contains iron which has a positive charge that attracts oxygen which has a negative charge (Fe2+ & O2-)
    • gives blood its red color
did you know
Did YOU know??
  • An individual blood cell takes about 60 seconds to make a complete circuit of the body!
6 where are wbcs made what is their general structure function
6. Where are WBCs made? What is their general structure & function?
  • Made from stem cells in red bone marrow and in the spleen
  • Larger than RBCs and contains a nucleus
  • Short life-span (a few hours to a few days) due to their ‘rough job’ duties
  • Destroys foreign and dead cells as well as makes antibodies

WBCs are outnumbered

by RBCs 700 to 1!

7 what are platelets what do they do
7. What are platelets? What do they do?
  • Cell fragments that help clot blood
  • Super small with no nucleus
  • Lifespan = 5-9 days
did you know1
Did YOU know???
  • Feeling hot, Hot, HOT!!
      • Blood temperature is approximately 100oF! (about 1.5 degrees hotter than normal body temperature).
8 what is blood clotting what are the steps
8. What is Blood clotting? What are the steps?
  • STOP the bleeding! (aka blood clotting)
  • Steps to healing a broken blood vessel:
    • 1. Blood vessel spasm: to lessen blood loss
    • 2. Platelet Aggregation: platelets stick to broken portion of the vessel and to each other.
    • 3. Platelet Plug: All of the platelets form a plug that can stop blood loss
