Overview

Blood is a type of connective tissue. Blood transports gases, nutrients, waste products, and hormones. It is involved in the regulation of homeostasis and the maintenance of pH, body temperature, fluid balance, and electrolyte level. Blood protects against diseases and blood loss. Blood is composed of plasma and erythrocytes, leucocytes and blood platelets. The plasma is composed of water, amino acid, proteins, carbohydrates, lipids, vitamins, and hormones. The erythrocytes are the most numerous cellular elements of blood. Platelets are minute fragments of cells consisting of a small amount of cytoplasm surrounded by a cell membrane. The main function of red blood cells is to transport gases. White blood cells function primarily to control various disease conditions. Blood platelets help close breaks in blood vessels.
