Answer:
Blood is both a tissue and a fluid. It is a tissue because it is a collection of similarly specialized cells that serve particular functions. These cells are suspended in a liquid matrix (plasma), which makes the blood fluid.
Step-by-step explanation:
A blood cell, also called a hematopoietic cell, hemocyte, or hematocyte is a cell produced through hematopoiesis and found mainly in the blood. Major types of blood cells include red blood cells (erythrocytes), white blood cells (leukocytes), and platelets (thrombocytes). Blood is a fluid connective tissue. It is different from other connective tissues as its matrix is fluid and has no fibres. The fluid matrix of blood is known as plasma. Other connective tissues have elastic and collagenous fibres, unlike blood which has none.
