Blood Composition and Functions

Blood is composed of about 55% plasma and 45% made up of three major types of cells: red blood cells (erythrocytes), white blood cells (leucocytes), and platelets (thrombocytes).

1. Respiration: carries O2 from the lung to the tissue and Co2 from the tissue to the lung. 2) Temperature regulation. 3) Nutrition: carries food absorbed from intestine to the cells which use them.

Blood transports leucocytes and antibodies, contributing to the body's immune response.
