Formed Elements

White Blood cell, Red blood cell, and platelet information

QuestionAnswer
Structure of erythrocytes Red blood cells; Biconcave; No nucleus or organelles; Hold hemoglobin protein
Function of erythrocytes Travel through capillaries from the lungs to different parts of the body
Structure of hemoglobin Globin protein that is made of 4 heme groups with an iron molecule at its center for oxygen binding; inside erythrocytes
Function of hemoglobin Carries almost 100% of our oxygen and 23% of our CO2
Structure of leukocytes White blood cells; Full cells; Divided into agranulocytes and granulocytes
Function of leukocytes Protect the body by fighting against pathogens and foreign debris for immunity
Structure of neutrophils Granulocytes; Most common leukocyte; Nucleus is pushed to the side; 50-70%; Picks up either stain; Multilobed nucleus
Function of neutrophils First phagocytic cells that arrive to attack pathogens and foreign debris; highly mobile
Structure of eosinophils Granulocyte; pick up the acidic stain (Eosin- acidophil); Multilobed nucleus; Appears more pink; 4th most common leukocyte (2-4%)
Function of eosinophils Phagocytic cells that are attracted to foreign debris to release the antigen-antibody complexes; stop the inflammatory response
Structure of basophils Granulocyte; Picks up the basic stain (purple and blue); Least common leukocyte (>1%)
Function of basophils Migrate to damaged tissue to release histamine and initiate inflammatory response
Structure of monocytes Largest leukocyte; Agranulocyte; 3rd most common leukocyte (2-8%)
Function of monocytes Once they leave the circulatory system and enter tissues they become macrophages; phagocytic cells
Structure of lymphocytes Smallest leukocyte; 2nd most common leukocyte (20-30%); Big nucleus compared to the cell; More common in the immune system
Function of lymphocytes B and T cells are involved in special immune functions against pathogens ; NK cells defend against cancers
Structure of platelets Cell fragments of megakaryocytic in red bone marrow
Function of platelets Blood clotting

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
