Blood Lab

Maybe stuff on Blood lab exam

TermDefinition
Erythrocyte An anucleate blood cell filled with hemoglobin that transports oxygen through the body
Leukocyte A type of blood cell that plays various roles in the immune system
Granulocyte A type of leukocyte that contains cytoplasmic granules that are visible with staining
Neutrophil A type of granulocyte with lilac-colored granules and multi-lobed nuclei; these cells are heavily involved in the phagocytosis of bacteria
Eosinophil A type of granulocyte with bilobed nuclei and red-stained granules; these cells are involved in allergy responses and fighting parasitic infections
Basophil A type of granulocyte with bilobed nuclei and dark purple-stained granules; these cells are involved in mediating inflammation
Agranulocyte A type of leukocyte that lacks visible cytoplasmic granules
T lymphocyte A type of agranulocyte that facilitates other functions of the immune response, kills cancer cells, and kills infected host cells.
B lymphocyte A type of agranulocyte that secretes antibodies when activated
Monocyte A type of agranulocyte with horseshoe-shaped nuclei that mature into macrophages, which are very active phagocytes.
Platelets Small cellular fragments involved in blood clotting
Antigen Unique glycoprotein on the surface of all cells and present on most biological molecules
Antiserum A solution containing antibodies that bind with specific antigens
Antibody Protein secreted by B lymphocytes; each antibody type binds to a specific antigen
Universal donor Type O– blood, which does not have A, B, or Rh antigens on the surface of its cells, so it can be accepted by a person of almost any blood type without triggering an immune response
Universal recipient A person with AB+ blood who has erythrocytes with A, B, and Rh antigens and so lacks anti-A, anti-B, and anti-Rh antibodies and can therefore accept all blood types without triggering an immune response
Erythrocyte Nucleus Shape,Cytoplasm and/or Granule Color,Function(s),Prevalence Anucleate; Red; Carry oxygen; 42–47% the volume of whole blood
Neutrophil Nucleus Shape,Cytoplasm and/or Granule Color,Function(s),Prevalence 3–5 lobes; Lilac cytoplasm, granules inconspicuous; Phagocytes active against bacteria; 50–70% of leukocytes
Eosinophil Nucleus Shape,Cytoplasm and/or Granule Color,Function(s),Prevalence Bilobed; Red; Defense against parasites and involved in allergy; 2–4% of leukocytes
Basophil Nucleus Shape,Cytoplasm and/or Granule Color,Function(s),Prevalence Lobed, often obscured by granules; Dark purple; Enhance inflammation; 0.5–1% of leukocytes
Lymphocyte Nucleus Shape,Cytoplasm and/or Granule Color,Function(s),Prevalence Spherical; Light blue; Attack foreign cells, make antibodies; 25–45% of leukocytes
Monocyte Nucleus Shape,Cytoplasm and/or Granule Color,Function(s),Prevalence U-shaped; Light blue; Active phagocytes; 3–8% of leukocytes
Platelet Nucleus Shape,Cytoplasm and/or Granule Color,Function(s),Prevalence Anucleate; Blue/purple, tiny fragments of cells; Clotting; < 1% of whole blood
A+ Antigens present; antibodies present A, Rh ; Anti-B
A- Antigens present; antibodies present A; Anti-B, Anti-Rh
B+ Antigens present; antibodies present B, Rh; anti-A
B- Antigens present; antibodies present B; Anti-A, Anti-Rh
AB+ Antigens present; antibodies present A, B, Rh; None
AB- Antigens present; antibodies present A,B; Anti-Rh
O+ Antigens present; antibodies present Rh; Anti-A, Anti-B
O- Antigens present; antibodies present None; Anti-A, Anti-B, Anti-Rh
T/F? The liquid portion of blood is known as plasma. True
T/F?Erythrocytes are generally involved in some aspect of the immune system. False: Leukocytes are involves
T/F? The granulocytes include the neutrophils, eosinophils, and basophils. True
T/F? Eosinophils are involved in mediating responses to parasitic worms and allergies. True
T/F? Lymphocytes leave the blood and become macrophages, very active phagocytes. False: Monocytes become macrophages
Erythrocytes carry oxygen on the protein.. hemoglobin
Antibodies are produced by ___ and bind to specific ____ on erythrocytes, causing ____ , or clumping of erythrocytes. B lymphocytes; antigens; agglutination

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.
