Document Summary
Blood performs a wide variety of functions, including: transporting elements throughout the body, regulating bodily functions, protecting the body through immune responses. Blood has predictable and stable characteristics that allow it to complete its functions. Accounts for 55% of the total volume of blood, and is made up of 92% water and 8% solutes. Solutes include plasma proteins (albumin, fibrinogen, and globulin), which account for. They also include inorganic salts (electrolytes such as sodium, potassium, and calcium), nutrients, and organic wastes, which account for the remaining 1% of blood. Contain hemoglobin to transport oxygen and carbon dioxide throughout the body. They are non true cells because they lack a nucleus. They are 8um in diameter and 2um thick. They are round or spindle shaped discs. They originate from megakaryocytes in the red bone marrow. Have a nucleus but do not contain hemoglobin. Neutrophils: the most abundant cell type as they make up 60-70% of all wbc"s.
