Why the blood is called a connective tissue.
Blood is called a fluid connective tissue because it develops from the mesoderm of the embryo like any other typical connective tissue and connects all the organ systems of the body by transporting oxygen, nutrients, hormones, etc., and removing wastes from these organs. Blood is a sticky fluid with a salty taste. It is bright red in arteries and darker and purple colored in the veins. Blood tissue is slightly alkaline and has a pH of 7.4
• It consists of a liquid matrix called the plasma, in which blood cells are present. So it can be said blood is an important lifeline.
• It travels all around the body in specialized blood vessels. Blood has many functions to play in the body. Primarily, it helps in the transport of gases, nutrients, hormones as well as the elimination of the waste materials.
• It has RBC and WBC. The RBCs have a pigment called hemoglobin, due to which blood appears red in colour. The WBCs help in protecting the body by attacking any foreign body that enters into the body, while the blood platelets are responsible for clotting of blood.

Each tissue has a specific function. The function of blood is to transport Oxygen and digested food to each cell and collect waste materials and carbon-dioxide. It also transports fats, and drugs molecules throughout the body, because of liquid nature it connects cells and tissues each other.
Blood is called a connective tissue because it carries with lots many digestive substances, Oxygen from lungs, foods from small intestine, and provides it to other tissues and organs of the body. Since, it connects heart, lungs and small intestine with other tissue of the body and works as a medium between them. Hence, it is called the connective tissue of the body.
