ANSWER: coranary system Aganulocytes ANSWER: are leukocytes that have such small granules in their cytoplasm. include both lymphocytes and moncytes. Granulocytes ANSWER: A group of leukocytes containing granules in their cytoplasm; neutrophils, eosinophils, basophils. The production of red blood cells. ANSWER: erythropo...

Know function and life span of RBCs and platelets. RBCs or erythrocytes: the most abundant cells of the blood – primarily responsible for tissue oxygenation Contains hemoglobin (carries the gases and electrolytes)  regulates diffusion through a cell’s plasma membrane. • Mature erythrocyte lacks a nucleus and cytoplasmic organelles (e.g., mitochondria),  cannot synthesize protein or carry out oxidative reactions (CANNOT UNDERGO MITOTIC DIVISION) • Has a limited life span of abo...

Which nursing role is not directly involved when providing family-centered approach to the pediatric population? 1. Advocacy 2. Case management 3. Patient education 4. Researcher - Answer 4. Researcher A nurse is working with pediatric clients in a research facility. The nurse recognizes that federal guidelines are in place that delineate which pediatrics clients must give assent for participation in research trials. Based upon the clients age, the nurse would seek assent from which child...

The locus control region (LCR) - correct answer coordinates expression of individual genes in the cluster (ex. the globin genes or 4 HOX gene clusters) The individual genes are activated in a temporal sequence (stage specific in development) (not spatially as in tissue specific) - correct answer tends to correspond exactly with their linear order in the chromosome Globin genes: - correct answer ...

What is hemoglobin composed of? - 4 heme, 4 iron, 4 globins What disorder does a defect in heme synthesis lead to? - Porphyria Porphyria - Deficiency in the enzymes of the porphyrin pathway leads to insufficient production of heme. The principal problem in these deficiencies is the accumulation of porphyrins, the heme precursors, which are toxic to tissue in high concentrations. What is methemoglobin? - Methemoglobin is a form of hemoglobin that contains ferric [Fe3+] iron and has a decrea...
