Document Summary
Return fluid to circulatory veins near heart. The only fluid tissue in human body. Components of blood: living cells (formed elements), non-living matrix (plasma) Salts (electrolytes): largely responsible for osmotic buffering of cells (acid- base balance) Nitrogenous waste products of metabolism: urea and uric acid. Erythrocytes: red blood cells (transport oxygen and aid transporting carbon dioxide), regulated by erythropoietin. Leukocytes: white blood cells (defense and immunity), regulated by colony stimulating factor and interleukins. Contain hemoglobin, which gives it it"s bright red colour when oxygen rich. Granulocytes: granules in cytoplasm can be stained, lobed nuclei, include neutrophils, eosinophils, and basophils. Agranulocytes: lack visible cytoplasmic granules, oval nuclei, include lymphocytes and monocytes (macrophages) Basophils: produce and release histamine, as part of inflammatory response. Monocytes: turn into phagocytes (macrophages) in tissues. Important factors in the process of clot formation in wound repair (hemostasis) Unable to divide, grow or synthesize proteins.
