chapter 19: BLOOD VOCAB

hemopoiesis

production of blood

hematopoietic stem cell (HSC)

liver, sleep, marrow thymus

differentiate into multiple type of blood cell without deciding what type

anucleate

cell without nucleus, erythrocytes

oxyhemoglobin

form of hemoglobin that has oxygen bind to iron

carbaminohemoglobin

proteins of hemoglobin bind carbon dioxide

carboxyhemoglobin

forms when carbon monoxide binds to iron in hemoglobin’s heme group. it binds more strongly than oxygen, changing hemoglobin’s shape and preventing oxygen release to tissues.

erythropoiesis

hematopoietic process that produces erythrocytes form HSCs that takes 5-7 days

anemia

decrease oxygen carrying capacity of blood

antibody

a protein produced by the immune system by plasma cells that bind to specific antigens

antigens

any foreign substance that the immune system recognizes as “non-self” and can trigger an immune response

agglutination

the clumping that occurs when antibodies bind to multiple antigens

phagocyte

ingest and destroy bacterial cells

macrophage

phagocytic cells that ingest dead and dying cells, bacteria, antigens, and other cellular debris

leukopoiesis

production of leukocytes

leukopenia

leukocytes count under the normal range

seen in cases of viral infections, immunodeficiency disorders, medication and poisoning

leukocytosis

leukocyte counts above normal range

seen in cases of bacterial infections allergies and dehydration

thrombopoiesis

production of platelets
