Summary Introduction
Introduction:
Blood is the fluid connective tissue, in which the formed elements (living blood cells) are suspended in a nonliving fluid matrix (plasma). The plasma is 90% water and remaining is dissolved hormones, proteins, and small molecules such as vitamins, fats, amino acids, carbohydrates, and
