Blood

TermDefinition
neutrophils - 3-5 lobed nucleus - phagocytize bacteria
lymphocytes - classic nucleus (oval/round shape) - specific immunity: B cells (make antibodies), T cells, natural killer cells (elevated in viral infections)
monocytes - ovoid, horseshoe, kidney shaped nucleus - phagocytize pathogens and debris - elevated in all kinds of infections
eosinophils - 2-4 lobed nucleus - kill parasites - elevated in allergies
basophils - U shaped nucleus (2 lobes) - secrete histamine and heparin (for inflammation)
sickle cell anemia abnormal hemoglobin within RBC causing sickled shape - unable to carry oxygen - sickled cells cannot pass through small capillaries = pain and ischemia
pernicious anemia vitamin B12 deficiency - reduced production of Intrinsic factor which decreases vitamin B12 absorption - causes large RBCs that don't hold oxygen well
iron deficient anemia inefficient RBC production = insufficient hemoglobin = decrease in O2 carrying capacity
eosinophilia excessive eosinophil production due to parasitic infection or allergies
lymphocytic leukemia DNA of B cell is damaged so it can't fight infection - crowds out healthy blood cells that normally fight infection

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

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.
