The food is digested into the simplest of the forms in t he digestive system. Blood carries the digested food or the nutrients absorbed from the intestine to the liver and then to other parts of the body. The food transported includes glucose, fatty acids, amino acids, glycero..

They are small biconcave circular cells also called erythrocytes . They are thicker at the edges than in the centre. The erythrocytes are flexible so that they can pass through the narrow capillaries easily. They number 5 million per cubic mm in adult males and 4.5 million per cubic mm in..
