Explanation:
Blood is a specialized body fluid. It has four fundamental components that are plasma, red blood cells, white blood cells, and platelets.
Plasma is the largest part of blood. It is a light yellow liquid. It contains water, salts, and enzymes in it. The main role of plasma is to take nutrients, hormones, and proteins to the body parts needed. It also collects waste products from the cells.
Red blood cells are the biconcave cells without a nucleus that carries oxygen from and to various tissues and organs. These are also known as erythrocytes. RBCs contain hemoglobin which gives blood its color and is iron-rich.
White blood cells are also known as leucocytes. They are colorless. These are again classified into granulocytes and agranulocytes. These help in immunity and defense mechanism. Granulocytes include eosinophils, basophils, and neutrophils. Agranulocytes include monocytes and lymphocytes.
Platelets or thrombocytes are specialized blood cells produced from bone marrow. They help in the clotting of blood.
