Document Summary
The cardiovascular system: heart and blood (based on chapter 21 and 22) Rbcs: hemoglobin, consists of four polypeptide subunits, each subunit contains a molecule of heme, heme is a porphyrin ring, each heme consists of an iron ion. Typically, the first wbc at the bacterial site. Nucleus is multilobed: eosinophils (normal range is 2 4%) 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%) Nucleus is usually hidden due to all the granules: agranulocytes, monocytes (normal range is 2 8%)3. Release chemicals to attract other phagocytic cells. Fibroblasts produce collagen fibers to surround an infected site. These collagen fibers can produce scar tissue. Nucleus is kidney-shaped or large oval-shaped: lymphocytes (normal range is 20 30%) Can differentiate to form t cells, b cells, and nk cells.
