Travels of the Red Blood Cell – Pathway Lab

Objectives:

  • To identify vessels, chambers, and valves of the mammalian heart.
  • Trace pathway of blood through heart.
  • Sequence events occurring during heart beat.

Materials:

  1. Set of Pathway Cards (23 total)
  2. Student Lab Packet
  3. Textbook

Pre-Lab Questions (1 pt each):

  1. What does blood give to the body? ______
  2. Define arteries:______
  3. Arteries carry blood WITH/WITHOUT oxygen and arteries send blood TOWARD/AWAY FROM the heart.
  4. Define veins:______
  5. Veins carry blood WITH/WITHOUT oxygen and veins send blood TOWARD/AWAY FROM the heart.
  6. Define Haversian canals: ______

Directions:

Use the stack of cards at your table to recreate the pathway of a red blood cell as he travels through the circulatory system. Hint: The blood cell will begin inside the body and travel back to the heart. You must figure out the correct order. Place the cards on the table in the correct order and, when you have finished, call your teacher to check. Write the order of your cards below after it has been checked.
