Answer 1

Ans:

• Blood is a connective tissue made up of cellular elements callled formed elements and an extracllular matrix called plasma.
• Whole blood is composed of plasma i.e. fluid portion of blood and formed elements i.e. blood cells and platelets.
• Plasma is the fluid portion of blood that contains proteins, ions, nutrients, hormones, antibodies, metabolites, enzymes, clotting factors, etc. The formed elements of blood are the red blood cells (erythrocytes), white blood cells (leukocytes), and platelets (thrombocytes).
• Plasma is straw-colored and makes up approximately 55% of whole blood volume. Formed elements i.e. blood cells and platelets make up approximately 45% of whole blood volume.
• Because of the formed elements and the plasma proteins and other solutes, blood is sticky and more viscous than water. It is also slightly alkaline, and its temperature is slightly higher than normal body temperature.
• Plasma circulates dissolved nutrients, such as glucose, amino acids, and fatty acids (dissolved in the blood or bound to plasma proteins), and removes waste products, such as carbon dioxide, urea, and lactic acid.
• Red blood cells contain hemoglobin, an iron-containing protein, which facilitates oxygen transport by reversibly binding to this respiratory gas and greatly increasing its solubility in blood. White blood cells help to resist infections and parasites. Platelets are important in the clotting of blood.
