Life Blood is composed of cells suspended in a liquid. The remaining liquid portion is the plasma, from which therapeutic fractions and derivatives are made. One pint of donated blood can be separated into several components to meet the needs of various patients.
Red cells transport oxygen to body cells and remove carbon dioxide.
Red cells need foods that contain iron such as meat, liver, eggs, green leafy vegetables and whole-grain bread to make them healthy. Red cells are produced in the bone marrow, at a normal rate of about 17 million cells per second. A disease related to red blood cells is Anemia . They attack bacteria by squeezing through capillary walls to reach the area of infection where they destroy bacteria. White blood cells are also made in the bone marrow, and are produced at twice the rate of red blood cells.
