BSC 2085C Lecture Notes - Whole Blood, Blood Plasma, Granulocyte
Document Summary
Whole blood all the components of the blood flowing through your vessels: whole blood makes up ~7-8% of your body weight, whole blood has a ph of ~7. 35-7. 45, whole blood has a temperature of 100. 4. Components of whole blood: plasma + formed elements. Erythrocytes make up 95% of formed elements and 40% of whole blood. Primary function is to transport oxygen (high with protein called hemoglobin which transports oxygen. They also transport nitric oxide and carbon dioxide) Leukocytes (wbcs) primary function is defense: neutrophils (granular) Physical features of blood (page 6 in lab manual for more details) Erythrocytes shape: 7-8 m in diameter, biconcave once fully mature (disc shaped) Platelets shape: are not cells at all, fragments of cells. The term granules are used in cell biology to refer to secretory vesicles. Granulocytes: neutrophils multi-segmented nucleus with very small granules in cytoplasm. Eosinophils bi-lobed nucleus, red colored granules in cytoplasm. Basophils bi-lobed nucleus with dark purple granules in cytoplasm.
