Document Summary
The cardiovascular system: heart and blood & the senses. Monocytes (2 8% of the wbcs: erythrocytes (red blood cells rbc) (99. 9% of formed elements) - transport oxygen and carbon dioxide. Allows the cell to be flexible as it travels through the circulatory system. Allows for more room for hemoglobin: significance of a lack of mitochondria: Without mitochondria, oxygen can be transported to the tissues instead. Neutrophils (normal range is 50 70%: granules contain chemicals to kill bacteria, typically the first wbc at the bacterial site, very active phagocytic cells, nucleus is multilobed. Eosinophils (normal range is 2 4%: granules release chemicals that reduce inflammation, attack a foreign substance that has reacted with circulating antibodies (such as an allergic reaction or parasites, typically have a bilobed nucleus. Basophils (normal range less than 1%: granules release histamine and heparin, histamine dilates blood vessels, heparin prevents abnormal blood clotting, nucleus is usually hidden due to all the granules, agranulocytes.
