Document Summary
Blood: hemacrotic levels tells you oxygen carrying capacity of blood (people with, animals that hold their breath for long times typically have higher hematocrit anemia have low hematocrit levels) levels than humans (ie. diving seals have 64% hem. Levels need this for oxygen to travel to tissues as they"re diving) Erythrocytes: lack nuclei and mitochondria (most vertebrates except birds" rbcs are, relatively short lifespan (continually produced by stem cells in bone marrow) nucleated) Leukocytes: 2 types invade the body: wbcs have mitochondria and nuclei, amoeboid movement (involved in engulfing foreign microorganisms that, classified according to histochemical staining properties, granular - when stained, can see dark staining granules in cytoplasm of. Eosinophils pink staining granules in cytoplasm (mobilized during cells allergic reactions to site of infection) Basophils blue staining (produce histamine and heparin) Neutrophils most abundant (phagocytes, involved in defense against microbial invasions and inflammatory reactions: agranular.
